Synced 2026-11-04._ --- ## Concept: Multi-Head Attention (MHA) > The original transformer attention: every head has its own queries, keys and values. Category: Attention Self-attention lets every token build its representation from a weighted mix of all earlier tokens. The weights come from comparing a token's query with every key; the values are what gets mixed. Multi-head attention runs several of these attention operations side by side, each in a smaller subspace, so different heads can track different relationships (syntax, coreference, position) at once. Their outputs are concatenated and projected back. In a decoder, a causal mask hides future tokens. Because every head stores its own keys and values, MHA has the largest KV cache of the common variants. **Trade-off:** Maximum expressiveness per layer, but the KV cache grows with heads × layers × tokens. ## Models using MHA (4) - [OLMo 3 (7B)](https://llm-atlas-7or.pages.dev/models/olmo-3-7b.md) — Ai2, 2025-11-20 - [Ouro-Thinking (2.6B)](https://llm-atlas-7or.pages.dev/models/ouro-thinking-2-6b.md) — ByteDance, 2025-10-29 - [OLMo 2 (7B)](https://llm-atlas-7or.pages.dev/models/olmo-2-7b.md) — Ai2, 2024-11-25 - [GPT-2 XL (1.5B)](https://llm-atlas-7or.pages.dev/models/gpt-2-xl-1-5b.md) — OpenAI, 2019-11-05 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/mha/ Web page: https://llm-atlas-7or.pages.dev/concepts/mha/ ## Concept: Grouped-Query Attention (GQA) > Several query heads share one key/value head, shrinking the KV cache with little quality loss. Category: Attention GQA keeps many query heads but groups them so each group reads from a single shared key/value head. With 32 query heads and 8 KV heads, the cache is four times smaller than MHA. Multi-query attention (MQA) is the extreme case with one KV head for everyone; GQA sits between MQA and MHA and became the default for dense open models from Llama 2 onwards. It is simple to implement, plays well with existing kernels, and is often combined with sliding-window layers for further savings. **Trade-off:** Large memory and bandwidth savings at inference for a small modelling cost. ## Models using GQA (78) -

Category: Attention Instead of sharing KV heads (as GQA does), MLA down-projects each token's keys and values into a compact latent and stores only that latent in the cache. At attention time it is projected back up. Introduced with DeepSeek V2 and popularised by DeepSeek V3/R1, MLA reported quality on par with or better than MHA while caching far less per token. A decoupled RoPE path handles positional information. Many large MoE models released since 2025 (Kimi, GLM-5, Mistral Large 3 and others) adopted MLA or variants of it. **Trade-off:** Very small KV cache, at the price of extra projections and a more complex implementation. ## Models using MLA (28) - [Mistral Large 4 (1T)](https://llm-atlas-7or.pages.dev/models/mistral-large-4.md) — Mistral AI, 2026-10-29 - [Ling 3.1 Flash (560B)](https://llm-atlas-7or.pages.dev/models/ling-3-1-flash.md) — InclusionAI, 2026-10-13 - [Ember-1 (2.8T)](https://llm-atlas-7or.pages.dev/models/ember-1.md) — Fireworks AI, 2026-09-23 - [Tencent Hy4-preview (770B-A49B)](https://llm-atlas-7or.pages.dev/models/tencent-hy4-preview-770b-a49b.md) — Tencent, 2026-08-28 - [GLM-5.3-Flash (320B)](https://llm-atlas-7or.pages.dev/models/glm-5-3-flash.md) — Z.ai, 2026-08-26 - [Ling 3.0 Flash (124B)](https://llm-atlas-7or.pages.dev/models/ling-3-0-flash.md) — InclusionAI, 2026-08-04 - [Kimi K3 (2.8T)](https://llm-atlas-7or.pages.dev/models/kimi-k3.md) — Moonshot AI, 2026-07-27 - [Motif 3 Beta (314B)](https://llm-atlas-7or.pages.dev/models/motif-3-beta.md) — Motif Technologies, 2026-07-21 - [GLM-5.2 (744B)](https://llm-atlas-7or.pages.dev/models/glm-5-2.md) — Z.ai, 2026-06-17 - [Kimi K2.7 Code (1T)](https://llm-atlas-7or.pages.dev/models/kimi-k2-7-code.md) — Moonshot AI, 2026-06-12 - [DeepSeek V4-Flash (284B)](https://llm-atlas-7or.pages.dev/models/deepseek-v4-flash.md) — DeepSeek, 2026-04-24 - [DeepSeek V4-Pro (1.6T)](https://llm-atlas-7or.pages.dev/models/deepseek-v4-pro.md) — DeepSeek, 2026-04-24 - [Ling 2.6 (1T)](https://llm-atlas-7or.pages.dev/models/ling-2-6-1t.md) — InclusionAI, 2026-04-23 - [Kimi K2.6 (1T)](https://llm-atlas-7or.pages.dev/models/kimi-k2-6.md) — Moonshot AI, 2026-04-20 - [GLM-5.1 (744B)](https://llm-atlas-7or.pages.dev/models/glm-5-1.md) — Z.ai, 2026-04-07 - [Mistral Small 4 (119B)](https://llm-atlas-7or.pages.dev/models/mistral-small-4.md) — Mistral AI, 2026-03-16 - [Sarvam (105B)](https://llm-atlas-7or.pages.dev/models/sarvam-105b.md) — Sarvam AI, 2026-03-03 - [Ling 2.5 (1T)](https://llm-atlas-7or.pages.dev/models/ling-2-5-1t.md) — InclusionAI, 2026-02-15 - [GLM-5 (744B)](https://llm-atlas-7or.pages.dev/models/glm-5-744b.md) — Z.ai, 2026-02-11 - [LongCat-Flash-Lite (68.5B-A3B)](https://llm-atlas-7or.pages.dev/models/longcat-flash-lite-68-5b-a3b.md) — Meituan, 2026-01-28 - [Kimi K2.5 (1T)](https://llm-atlas-7or.pages.dev/models/kimi-k2-5.md) — Moonshot AI, 2026-01-27 - [GLM-4.7 (355B)](https://llm-atlas-7or.pages.dev/models/glm-4-7-355b.md) — Z.ai, 2025-12-22 - [Mistral Large 3 (673B)](https://llm-atlas-7or.pages.dev/models/mistral-large-3.md) — Mistral AI, 2025-12-02 - [DeepSeek V3.2 (671B)](https://llm-atlas-7or.pages.dev/models/deepseek-v3-2.md) — DeepSeek, 2025-12-01 - [Kimi Linear (48B-A3B)](https://llm-atlas-7or.pages.dev/models/kimi-linear-48b-a3b.md) — Moonshot AI, 2025-10-30 - [Kimi K2 (1T)](https://llm-atlas-7or.pages.dev/models/kimi-k2.md) — Moonshot AI, 2025-07-10 - [DeepSeek R1 (671B)](https://llm-atlas-7or.pages.dev/models/deepseek-r1.md) — DeepSeek, 2025-01-20 - [DeepSeek V3 (671B)](https://llm-atlas-7or.pages.dev/models/deepseek-v3.md) — DeepSeek, 2024-12-26 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/mla/ Web page: https://llm-atlas-7or.pages.dev/concepts/mla/ ## Concept: Sliding Window Attention (SWA) > Some layers only attend to a local window of recent tokens instead of the whole context. Category: Attention Local (sliding-window) layers restrict each token to the last N tokens, so their KV cache stops growing once the window is full. A few global layers are kept so information can still travel across the whole context. Gemma 3 made the pattern famous with a 5:1 local-to-global ratio and a 1,024-token window. The ratio and window size are the main knobs, and it is very often paired with GQA. **Trade-off:** Cheap long contexts; the risk is weaker long-range recall if too few global layers remain. ## Models using SWA (38) - [LFM3 (1.7B)](https://llm-atlas-7or.pages.dev/models/lfm3-1-7b.md) — Liquid AI, 2026-10-27 - [Recursive Flint (40B-A2.5B)](https://llm-atlas-7or.pages.dev/models/recursive-flint-40b-a2-5b.md) — Recursive, 2026-10-18 - [Reflection Beam (501B)](https://llm-atlas-7or.pages.dev/models/reflection-beam-501b.md) — Reflection, 2026-10-16 - [Dory1.0 (4B)](https://llm-atlas-7or.pages.dev/models/dory1-0-4b.md) — NVIDIA, 2026-10-16 - [Muse Spark Open (816B-A42B)](https://llm-atlas-7or.pages.dev/models/muse-spark-open-816b-a42b.md) — Meta, 2026-10-15 - [Kolibri-1 (78B)](https://llm-atlas-7or.pages.dev/models/kolibri-1-78b.md) — Aleph Alpha, 2026-10-03 - [Naive-N0.5-Flash (309B)](https://llm-atlas-7or.pages.dev/models/naive-n0-5-flash-309b.md) — NaiveAI, 2026-09-27 - [Xiaomi MiMo-V2.6-Flash-RL (309B)](https://llm-atlas-7or.pages.dev/models/xiaomi-mimo-v2-6-flash-rl-309b.md) — Xiaomi, 2026-09-21 - [Xiaomi MiMo-V2.6-Pro-RL (1.02T)](https://llm-atlas-7or.pages.dev/models/xiaomi-mimo-v2-6-pro-rl-1-02t.md) — Xiaomi, 2026-09-21 - [Step-5 Preview (600B)](https://llm-atlas-7or.pages.dev/models/step-5-preview-600b.md) — StepFun, 2026-09-20 - [DeepSeek V4.1-Flash (552B)](https://llm-atlas-7or.pages.dev/models/deepseek-v4-1-flash.md) — DeepSeek, 2026-09-10 - [Muse Glimmer (30B)](https://llm-atlas-7or.pages.dev/models/muse-glimmer-30b.md) — Meta, 2026-08-10 - [Laguna S 2.1 (118B)](https://llm-atlas-7or.pages.dev/models/laguna-s-2-1.md) — Poolside, 2026-07-21 - [Motif 3 Beta (314B)](https://llm-atlas-7or.pages.dev/models/motif-3-beta.md) — Motif Technologies, 2026-07-21 - [Inkling (975B)](https://llm-atlas-7or.pages.dev/models/inkling.md) — Thinking Machines Lab, 2026-07-15 - [Laguna XS 2.1 (33B)](https://llm-atlas-7or.pages.dev/models/laguna-xs-2-1.md) — Poolside, 2026-07-02 - [North Mini Code (30B-A3B)](https://llm-atlas-7or.pages.dev/models/north-mini-code-30b-a3b.md) — Cohere, 2026-06-05 - [Gemma 4 (12B)](https://llm-atlas-7or.pages.dev/models/gemma-4-12b.md) — Google, 2026-06-03 - [JetBrains Mellum2 Thinking (12B-A2.5B)](https://llm-atlas-7or.pages.dev/models/jetbrains-mellum2-thinking-12b-a2-5b.md) — JetBrains, 2026-06-01 - [Laguna XS.2 (33B)](https://llm-atlas-7or.pages.dev/models/laguna-xs-2.md) — Poolside, 2026-04-28 - [Xiaomi MiMo-V2.5 (310B)](https://llm-atlas-7or.pages.dev/models/xiaomi-mimo-v2-5-310b.md) — Xiaomi, 2026-04-22 - [Xiaomi MiMo-V2.5-Pro (1.02T)](https://llm-atlas-7or.pages.dev/models/xiaomi-mimo-v2-5-pro-1-02t.md) — Xiaomi, 2026-04-22 - [Gemma 4 (31B)](https://llm-atlas-7or.pages.dev/models/gemma-4-31b.md) — Google, 2026-04-02 - [Gemma 4 (26B-A4B)](https://llm-atlas-7or.pages.dev/models/gemma-4-26b-a4b.md) — Google, 2026-04-02 - [Gemma 4 (E2B)](https://llm-atlas-7or.pages.dev/models/gemma-4-e2b.md) — Google, 2026-04-02 - [Gemma 4 (E4B)](https://llm-atlas-7or.pages.dev/models/gemma-4-e4b.md) — Google, 2026-04-02 - [Tiny Aya (3.35B)](https://llm-atlas-7or.pages.dev/models/tiny-aya-3-35b.md) — Cohere, 2026-02-13 - [MiniMax-M2.5 (230B)](https://llm-atlas-7or.pages.dev/models/minimax-m2-5-230b.md) — MiniMax, 2026-02-12 - [Step 3.5 Flash (196B)](https://llm-atlas-7or.pages.dev/models/step-3-5-flash-196b.md) — StepFun, 2026-02-01 - [Arcee AI Trinity Large (400B)](https://llm-atlas-7or.pages.dev/models/arcee-ai-trinity-large-400b.md) — Arcee AI, 2026-01-27 - [Xiaomi MiMo-V2-Flash (309B)](https://llm-atlas-7or.pages.dev/models/xiaomi-mimo-v2-flash-309b.md) — Xiaomi, 2025-12-16 - [OLMo 3 (32B)](https://llm-atlas-7or.pages.dev/models/olmo-3-32b.md) — Ai2, 2025-11-20 - [OLMo 3 (7B)](https://llm-atlas-7or.pages.dev/models/olmo-3-7b.md) — Ai2, 2025-11-20 - [Gemma 3 (270M)](https://llm-atlas-7or.pages.dev/models/gemma-3-270m.md) — Google, 2025-08-14 - [GPT-OSS (120B)](https://llm-atlas-7or.pages.dev/models/gpt-oss-120b.md) — OpenAI, 2025-08-04 - [GPT-OSS (20B)](https://llm-atlas-7or.pages.dev/models/gpt-oss-20b.md) — OpenAI, 2025-08-04 - [Mistral Small 3.1 (24B)](https://llm-atlas-7or.pages.dev/models/mistral-small-3-1-24b.md) — Mistral AI, 2025-03-18 - [Gemma 3 (27B)](https://llm-atlas-7or.pages.dev/models/gemma-3-27b.md) — Google, 2025-03-11 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/swa/ Web page: https://llm-atlas-7or.pages.dev/concepts/swa/ ## Concept: Layer-wise attention budgeting (Attention budgeting) > Different layers get different attention budgets: head counts, windows or full context. Category: Attention Rather than giving every layer an identical attention setup, the model spends more attention capacity in some layers and less in others.

Category: Attention After the softmax attention is computed, a gate derived from the layer input multiplies the result element-wise. The gate can damp heads or channels that are not useful for the current token. Qwen3-Next and Qwen3.5 use it in their full-attention layers next to linear-attention layers; Trinity Large uses it in an attention-only stack. Reported benefits include better training stability and fewer attention-sink artefacts. **Trade-off:** A cheap extra projection that adds control and stability to the attention output. ## Models using Gated attention (21) - [LFM3 (1.7B)](https://llm-atlas-7or.pages.dev/models/lfm3-1-7b.md) — Liquid AI, 2026-10-27 - [Reflection Beam (501B)](https://llm-atlas-7or.pages.dev/models/reflection-beam-501b.md) — Reflection, 2026-10-16 - [Dory1.0 (4B)](https://llm-atlas-7or.pages.dev/models/dory1-0-4b.md) — NVIDIA, 2026-10-16 - [Muse Spark Open (816B-A42B)](https://llm-atlas-7or.pages.dev/models/muse-spark-open-816b-a42b.md) — Meta, 2026-10-15 - [Ling 3.1 Flash (560B)](https://llm-atlas-7or.pages.dev/models/ling-3-1-flash.md) — InclusionAI, 2026-10-13 - [Ember-1 (2.8T)](https://llm-atlas-7or.pages.dev/models/ember-1.md) — Fireworks AI, 2026-09-23 - [Step-5 Preview (600B)](https://llm-atlas-7or.pages.dev/models/step-5-preview-600b.md) — StepFun, 2026-09-20 - [Tencent Hy4-preview (770B-A49B)](https://llm-atlas-7or.pages.dev/models/tencent-hy4-preview-770b-a49b.md) — Tencent, 2026-08-28 - [Qwen3.8-Flash-Next (125B-A6B)](https://llm-atlas-7or.pages.dev/models/qwen3-8-flash-next-125b-a6b.md) — Alibaba Cloud, 2026-08-26 - [Ornith 1.5 (35B-A3B)](https://llm-atlas-7or.pages.dev/models/ornith-1-5-35b-a3b.md) — Ornith, 2026-08-23 - [Qwen3.8 (27B)](https://llm-atlas-7or.pages.dev/models/qwen3-8-27b.md) — Alibaba Cloud, 2026-08-14 - [Muse Glimmer (30B)](https://llm-atlas-7or.pages.dev/models/muse-glimmer-30b.md) — Meta, 2026-08-10 - [Ling 3.0 Flash (124B)](https://llm-atlas-7or.pages.dev/models/ling-3-0-flash.md) — InclusionAI, 2026-08-04 - [Kimi K3 (2.8T)](https://llm-atlas-7or.pages.dev/models/kimi-k3.md) — Moonshot AI, 2026-07-27 - [Solar Open 2 (250B)](https://llm-atlas-7or.pages.dev/models/solar-open-2.md) — Upstage, 2026-07-22 - [BTL-3 (27B)](https://llm-atlas-7or.pages.dev/models/btl-3-27b.md) — Bad Theory Labs, 2026-07-20 - [Qwen3.6 (27B)](https://llm-atlas-7or.pages.dev/models/qwen3-6-27b.md) — Alibaba Cloud, 2026-04-22 - [Qwen3.6 (35B-A3B)](https://llm-atlas-7or.pages.dev/models/qwen3-6-35b-a3b.md) — Alibaba Cloud, 2026-04-15 - [Qwen3.5 (397B)](https://llm-atlas-7or.pages.dev/models/qwen3-5-397b.md) — Alibaba Cloud, 2026-02-16 - [Arcee AI Trinity Large (400B)](https://llm-atlas-7or.pages.dev/models/arcee-ai-trinity-large-400b.md) — Arcee AI, 2026-01-27 - [Qwen3 Next (80B-A3B)](https://llm-atlas-7or.pages.dev/models/qwen3-next-80b-a3b.md) — Alibaba Cloud, 2025-09-09 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/gated-attention/ Web page: https://llm-atlas-7or.pages.dev/concepts/gated-attention/ ## Concept: Hybrid Attention (Hybrid attention) > Mixes cheap linear-attention or state-space layers with a few full-attention layers. Category: Attention Linear attention variants (Gated DeltaNet, Kimi Delta Attention, Lightning Attention) and state-space layers such as Mamba-2 keep a fixed-size recurrent state instead of a per-token KV cache, so their memory does not grow with context. Because they are weaker at precise retrieval, hybrids interleave them with a smaller number of full-attention layers, for example three linear layers per full-attention layer in the Qwen pattern. **Trade-off:** Much lower long-context memory and compute, trading away some exact recall in the linear layers. ## Models using Hybrid attention (24) - [Nemotron 3.5 Super VL (120B-A12B)](https://llm-atlas-7or.pages.dev/models/nemotron-3-5-super-vl-120b-a12b.md) — NVIDIA, 2026-10-15 - [Ling 3.1 Flash (560B)](https://llm-atlas-7or.pages.dev/models/ling-3-1-flash.md) — InclusionAI, 2026-10-13 - [Ember-1 (2.8T)](https://llm-atlas-7or.pages.dev/models/ember-1.md) — Fireworks AI, 2026-09-23 - [GLM-5.3-Flash (320B)](https://llm-atlas-7or.pages.dev/models/glm-5-3-flash.md) — Z.ai, 2026-08-26 - [Qwen3.8-Flash-Next (125B-A6B)](https://llm-atlas-7or.pages.dev/models/qwen3-8-flash-next-125b-a6b.md) — Alibaba Cloud, 2026-08-26 - [Ornith 1.5 (35B-A3B)](https://llm-atlas-7or.pages.dev/models/ornith-1-5-35b-a3b.md) — Ornith, 2026-08-23 - [Qwen3.8 (27B)](https://llm-atlas-7or.pages.dev/models/qwen3-8-27b.md) — Alibaba Cloud, 2026-08-14 - [Nemotron 3.5 Lightning (30B-A3B)](https://llm-atlas-7or.pages.dev/models/nemotron-3-5-lightning-30b-a3b.md) — NVIDIA, 2026-08-11 - [Ling 3.0 Flash (124B)](https://llm-atlas-7or.pages.dev/models/ling-3-0-flash.md) — InclusionAI, 2026-08-04 - [Kimi K3 (2.8T)](https://llm-atlas-7or.pages.dev/models/kimi-k3.md) — Moonshot AI, 2026-07-27 - [Solar Open 2 (250B)](https://llm-atlas-7or.pages.dev/models/solar-open-2.md) — Upstage, 2026-07-22 - [BTL-3 (27B)](https://llm-atlas-7or.pages.dev/models/btl-3-27b.md) — Bad Theory Labs, 2026-07-20 - [Soofi S (30B-A3B)](https://llm-atlas-7or.pages.dev/models/soofi-s-30b-a3b.md) — SOOFI Consortium, 2026-07-10 - [Nemotron 3 Ultra (550B-A55B)](https://llm-atlas-7or.pages.dev/models/nemotron-3-ultra-550b-a55b.md) — NVIDIA, 2026-06-04 - [Ling 2.6 (1T)](https://llm-atlas-7or.pages.dev/models/ling-2-6-1t.md) — InclusionAI, 2026-04-23 - [Qwen3.6 (27B)](https://llm-atlas-7or.pages.dev/models/qwen3-6-27b.md) — Alibaba Cloud, 2026-04-22 - [Qwen3.6 (35B-A3B)](https://llm-atlas-7or.pages.dev/models/qwen3-6-35b-a3b.md) — Alibaba Cloud, 2026-04-15 - [Nemotron 3 Nano (4B)](https://llm-atlas-7or.pages.dev/models/nemotron-3-nano-4b.md) — NVIDIA, 2026-03-16 - [Nemotron 3 Super (120B-A12B)](https://llm-atlas-7or.pages.dev/models/nemotron-3-super-120b-a12b.md) — NVIDIA, 2026-03-11 - [Qwen3.5 (397B)](https://llm-atlas-7or.pages.dev/models/qwen3-5-397b.md) — Alibaba Cloud, 2026-02-16 - [Ling 2.5 (1T)](https://llm-atlas-7or.pages.dev/models/ling-2-5-1t.md) — InclusionAI, 2026-02-15 - [Nemotron 3 Nano (30B-A3B)](https://llm-atlas-7or.pages.dev/models/nemotron-3-nano-30b-a3b.md) — NVIDIA, 2025-12-04 - [Kimi Linear (48B-A3B)](https://llm-atlas-7or.pages.dev/models/kimi-linear-48b-a3b.md) — Moonshot AI, 2025-10-30 - [Qwen3 Next (80B-A3B)](https://llm-atlas-7or.pages.dev/models/qwen3-next-80b-a3b.md) — Alibaba Cloud, 2025-09-09 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/hybrid-attention/ Web page: https://llm-atlas-7or.pages.dev/concepts/hybrid-attention/ ## Concept: Short Convolution (ShortConv) > A tiny causal depthwise convolution (kernel ≈ 4) that mixes each channel over the last few tokens. Category: Attention Each channel is convolved over a handful of recent positions with its own small kernel, and future positions are never seen. It is extremely cheap and gives layers a built-in notion of local order. Kimi Linear applies ShortConv to the queries, keys and values in its delta-attention layers; Inkling places several ShortConv modules in every block. LFM-style models use convolutions as the main token mixer. **Trade-off:** Near-free local mixing that complements linear attention, but it cannot see far by itself. ## Models using ShortConv (10) - [LFM3 (1.7B)](https://llm-atlas-7or.pages.dev/models/lfm3-1-7b.md) — Liquid AI, 2026-10-27 - [Ling 3.1 Flash (560B)](https://llm-atlas-7or.pages.dev/models/ling-3-1-flash.md) — InclusionAI, 2026-10-13 - [Ember-1 (2.8T)](https://llm-atlas-7or.pages.dev/models/ember-1.md) — Fireworks AI, 2026-09-23 - [GLM-5.3-Flash (320B)](https://llm-atlas-7or.pages.dev/models/glm-5-3-flash.md) — Z.ai, 2026-08-26 - [Ornith 1.5 (35B-A3B)](https://llm-atlas-7or.pages.dev/models/ornith-1-5-35b-a3b.md) — Ornith, 2026-08-23 - [Ling 3.0 Flash (124B)](https://llm-atlas-7or.pages.dev/models/ling-3-0-flash.md) — InclusionAI, 2026-08-04 - [Kimi K3 (2.8T)](https://llm-atlas-7or.pages.dev/models/kimi-k3.md) — Moonshot AI, 2026-07-27 - [Solar Open 2 (250B)](https://llm-atlas-7or.pages.dev/models/solar-open-2.md) — Upstage, 2026-07-22 - [Inkling (975B)](https://llm-atlas-7or.pages.dev/models/inkling.md) — Thinking Machines Lab, 2026-07-15 - [Kimi Linear (48B-A3B)](https://llm-atlas-7or.pages.dev/models/kimi-linear-48b-a3b.md) — Moonshot AI, 2025-10-30 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/shortconv/ Web page: https://llm-atlas-7or.pages.dev/concepts/shortconv/ ## Concept: DeepSeek Sparse Attention (DSA) > A lightweight indexer scores past tokens and each query attends only to its top-k picks. Category: Sparse & compressed attention DSA adds a small, fast indexer that estimates how relevant each earlier token is to the current query. A selector keeps the top-k tokens (2,048 in DeepSeek's code), and full attention is computed only over those. Unlike a fixed sliding window, the selection is learned and can reach anywhere in the context. It was introduced with DeepSeek V3.2 on top of MLA and later adopted by GLM-5. **Trade-off:** Long-context attention cost grows with k instead of the full sequence length. ## Models using DSA (10) - [Mistral Large 4 (1T)](https://llm-atlas-7or.pages.dev/models/mistral-large-4.md) — Mistral AI, 2026-10-29 - [Naive-N0.5-Flash (309B)](https://llm-atlas-7or.pages.dev/models/naive-n0-5-flash-309b.md) — NaiveAI, 2026-09-27 - [Tencent Hy4-preview (770B-A49B)](https://llm-atlas-7or.pages.dev/models/tencent-hy4-preview-770b-a49b.md) — Tencent, 2026-08-28 - [GLM-5.3-Flash (320B)](https://llm-atlas-7or.pages.dev/models/glm-5-3-flash.md) — Z.ai, 2026-08-26 - [GLM-5.2 (744B)](https://llm-atlas-7or.pages.dev/models/glm-5-2.md) — Z.ai, 2026-06-17 - [DeepSeek V4-Flash (284B)](https://llm-atlas-7or.pages.dev/models/deepseek-v4-flash.md) — DeepSeek, 2026-04-24 - [DeepSeek V4-Pro (1.6T)](https://llm-atlas-7or.pages.dev/models/deepseek-v4-pro.md) — DeepSeek, 2026-04-24 - [GLM-5.1 (744B)](https://llm-atlas-7or.pages.dev/models/glm-5-1.md) — Z.ai, 2026-04-07 - [GLM-5 (744B)](https://llm-atlas-7or.pages.dev/models/glm-5-744b.md) — Z.ai, 2026-02-11 - [DeepSeek V3.2 (671B)](https://llm-atlas-7or.pages.dev/models/deepseek-v3-2.md) — DeepSeek, 2025-12-01 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/deepseek-sparse-attention/ Web page: https://llm-atlas-7or.pages.dev/concepts/deepseek-sparse-attention/ ## Concept: IndexShare (IndexShare) > Nearby layers reuse the token selection computed by one DSA indexer. Category: Sparse & compressed attention Computing a DSA indexer in every layer still costs time. IndexShare computes the top-k selection once and lets the following layers (three, in GLM-5.2) reuse it. The goal is to keep most of the quality of per-layer selection while cutting the indexer overhead. **Trade-off:** Fewer indexer passes; the selection is slightly less tailored to each layer. ## Models using IndexShare (3) - [Mistral Large 4 (1T)](https://llm-atlas-7or.pages.dev/models/mistral-large-4.md) — Mistral AI, 2026-10-29 - [Tencent Hy4-preview (770B-A49B)](https://llm-atlas-7or.pages.dev/models/tencent-hy4-preview-770b-a49b.md) — Tencent, 2026-08-28 - [GLM-5.2 (744B)](https://llm-atlas-7or.pages.dev/models/glm-5-2.md) — Z.ai, 2026-06-17 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/indexshare/ Web page: https://llm-atlas-7or.pages.dev/concepts/indexshare/ ## Concept: Qwen Sparse Attention (QSA) > Like DSA, but the indexer picks whole four-token blocks rather than single tokens. Category: Sparse & compressed attention The indexer averages keys within each complete four-token block, scores the pooled keys against the query, and expands the winning blocks back into their tokens. The current incomplete block is always visible. Selecting contiguous blocks is friendlier to memory access patterns than scattering over individual token positions. **Trade-off:** Hardware-friendlier sparse reads at a coarser selection granularity. ## Models using QSA (1) - [Qwen3.8-Flash-Next (125B-A6B)](https://llm-atlas-7or.pages.dev/models/qwen3-8-flash-next-125b-a6b.md) — Alibaba Cloud, 2026-08-26 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/qwen-sparse-attention/ Web page: https://llm-atlas-7or.pages.dev/concepts/qwen-sparse-attention/ ## Concept: Compressed Sparse & Heavily Compressed Attention (CSA / HCA) > Pool groups of older tokens into fewer KV entries, compressing along the sequence axis. Category: Sparse & compressed attention MLA shrinks each token's cache entry; CSA and HCA reduce how many entries there are. Groups of past tokens are pooled into compressed entries. CSA compresses moderately and reads a sparse selection of entries; HCA compresses aggressively and reads all of them. DeepSeek V4 combines both to reach million-token contexts. **Trade-off:** Drastically smaller long-context caches, with some loss of token-level detail in the far past. ## Models using CSA / HCA (2) - [DeepSeek V4-Flash (284B)](https://llm-atlas-7or.pages.dev/models/deepseek-v4-flash.md) — DeepSeek, 2026-04-24 - [DeepSeek V4-Pro (1.6T)](https://llm-atlas-7or.pages.dev/models/deepseek-v4-pro.md) — DeepSeek, 2026-04-24 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/csa-hca/ Web page: https://llm-atlas-7or.pages.dev/concepts/csa-hca/ ## Concept: Compressed Convolutional Attention (CCA) > Attention computed directly in a compressed latent space, with convolutional mixing. Category: Sparse & compressed attention Where MLA uses a latent mainly as a compact cache format and decompresses it for attention, CCA performs the attention operation itself in the compressed space and adds convolutions to mix information. ZAYA1-8B by Zyphra uses CCA together with grouped-query attention. **Trade-off:** Saves both cache memory and attention FLOPs; still a young technique. ## Models using CCA (1) - [ZAYA1-8B (8.4B)](https://llm-atlas-7or.pages.dev/models/zaya1-8b.md) — Zyphra, 2026-05-06 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/compressed-convolutional-attention/ Web page: https://llm-atlas-7or.pages.dev/concepts/compressed-convolutional-attention/ ## Concept: Mixture of Experts (MoE) > Many feed-forward experts, but a router sends each token to only a few of them. Category: Feed-forward & experts The single feed-forward block is replaced by many expert blocks. A router picks a small number (often 8) per token, so the model has a huge total parameter count while each token only touches a fraction of them, the active parameters. Many designs add a shared expert that every token uses, and keep the first few layers dense. DeepSeek V3 is the template much of the 2025–2026 wave followed. **Trade-off:** More knowledge capacity per unit of compute, but all experts must still fit in memory. ## Models using MoE (79) - [Mistral Large 4 (1T)](https://llm-atlas-7or.pages.dev/models/mistral-large-4.md) — Mistral AI, 2026-10-29 -

Category: Feed-forward & experts Tokens are projected down before they enter the routed experts and projected back up afterwards. Experts become cheaper, so a model can afford more of them or activate more per token. Nemotron 3 Super and Ultra, Kimi K3 and Muse Spark Open use this layout with different compression ratios and normalization details. **Trade-off:** Cheaper experts and communication; the bottleneck must be sized carefully. ## Models using Latent MoE (5) - [Muse Spark Open (816B-A42B)](https://llm-atlas-7or.pages.dev/models/muse-spark-open-816b-a42b.md) — Meta, 2026-10-15 - [Nemotron 3.5 Super VL (120B-A12B)](https://llm-atlas-7or.pages.dev/models/nemotron-3-5-super-vl-120b-a12b.md) — NVIDIA, 2026-10-15 - [Ember-1 (2.8T)](https://llm-atlas-7or.pages.dev/models/ember-1.md) — Fireworks AI, 2026-09-23 - [Kimi K3 (2.8T)](https://llm-atlas-7or.pages.dev/models/kimi-k3.md) — Moonshot AI, 2026-07-27 - [Nemotron 3 Super (120B-A12B)](https://llm-atlas-7or.pages.dev/models/nemotron-3-super-120b-a12b.md) — NVIDIA, 2026-03-11 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/latent-moe/ Web page: https://llm-atlas-7or.pages.dev/concepts/latent-moe/ ## Concept: PolyNorm (PolyNorm) > A learned activation mixing normalised linear, quadratic and cubic terms. Category: Feed-forward & experts Feed-forward blocks moved from GELU to SwiGLU-style gating with a fixed SiLU. PolyNorm replaces that fixed function with a learned combination of separately RMS-normalised powers of the pre-activation. Motif 3 Beta uses a grouped PolyNorm inside each expert. **Trade-off:** A more flexible nonlinearity for a little extra compute and tuning. ## Models using PolyNorm (1) - [Motif 3 Beta (314B)](https://llm-atlas-7or.pages.dev/models/motif-3-beta.md) — Motif Technologies, 2026-07-21 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/polynorm/ Web page: https://llm-atlas-7or.pages.dev/concepts/polynorm/ ## Concept: Manifold-constrained Hyper-Connections (mHC) > Several parallel residual streams with learned, constrained mixing between them. Category: Residual stream The single residual stream is widened into several streams (four in DeepSeek V4). Learned mappings decide how sublayer inputs are read from, and outputs written back to, these streams. Unconstrained hyper-connections can amplify signals and destabilise training; mHC constrains the mixing matrix to a well-behaved manifold so information is mixed without blowing up. DeepSeek V4.1 introduced a cheaper single-pass variant. **Trade-off:** A richer residual path for a modest training overhead. ## Models using mHC (6) - [DeepSeek V4.1-Flash (552B)](https://llm-atlas-7or.pages.dev/models/deepseek-v4-1-flash.md) — DeepSeek, 2026-09-10 - [Tencent Hy4-preview (770B-A49B)](https://llm-atlas-7or.pages.dev/models/tencent-hy4-preview-770b-a49b.md) — Tencent, 2026-08-28 - [GLM-5.3-Flash (320B)](https://llm-atlas-7or.pages.dev/models/glm-5-3-flash.md) — Z.ai, 2026-08-26 - [Motif 3 Beta (314B)](https://llm-atlas-7or.pages.dev/models/motif-3-beta.md) — Motif Technologies, 2026-07-21 - [DeepSeek V4-Flash (284B)](https://llm-atlas-7or.pages.dev/models/deepseek-v4-flash.md) — DeepSeek, 2026-04-24 - [DeepSeek V4-Pro (1.6T)](https://llm-atlas-7or.pages.dev/models/deepseek-v4-pro.md) — DeepSeek, 2026-04-24 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/mhc/ Web page: https://llm-atlas-7or.pages.dev/concepts/mhc/ ## Concept: Gated Residuals (GR) > Gated read/write modules over four residual streams, without mHC's mixing matrix. Category: Residual stream Before a sublayer, a GR Read module normalises each of four residual streams, gates them element-wise and averages them into a normal-width input. Afterwards, GR Write adds the output back to all four streams with learned gates. It was introduced with Qwen3.8-Flash-Next and is related in spirit to mHC. **Trade-off:** Wider residual capacity with simple gating instead of a constrained mixing matrix. ## Models using GR (1) - [Qwen3.8-Flash-Next (125B-A6B)](https://llm-atlas-7or.pages.dev/models/qwen3-8-flash-next-125b-a6b.md) — Alibaba Cloud, 2026-08-26 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/gated-residuals/ Web page: https://llm-atlas-7or.pages.dev/concepts/gated-residuals/ ## Concept: Attention Residuals (AttnRes) > Learned, attention-style weights over earlier layer outputs replace the plain residual sum. Category: Residual stream A standard residual connection adds every earlier update with weight one. AttnRes lets each layer attend over earlier layer outputs and weight their contributions. Full and block variants exist; Kimi Linear already used the idea. Reported gains are consistent but modest, for a few percent extra training and inference cost. **Trade-off:** Smarter depth-wise information flow for a small overhead. ## Models using AttnRes (3) - [Ember-1 (2.8T)](https://llm-atlas-7or.pages.dev/models/ember-1.md) — Fireworks AI, 2026-09-23 - [Kimi K3 (2.8T)](https://llm-atlas-7or.pages.dev/models/kimi-k3.md) — Moonshot AI, 2026-07-27 - [Kimi Linear (48B-A3B)](https://llm-atlas-7or.pages.dev/models/kimi-linear-48b-a3b.md) — Moonshot AI, 2025-10-30 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/attention-residuals/ Web page: https://llm-atlas-7or.pages.dev/concepts/attention-residuals/ ## Concept: Looped Transformer (Looped depth) > The same blocks are applied several times, reusing weights across depth. Category: Residual stream With L distinct blocks applied T times, the model gets L × T effective layers for the parameter cost of L. It is depth-wise weight tying, sometimes called recurrent depth. Nanbeige 4.2 uses two fixed passes, Ouro uses four passes with a learned exit gate, and Dory1.0 loops a shared middle stack. **Trade-off:** More compute per parameter; extra passes add latency and, depending on the design, KV cache. ## Models using Looped depth (3) - [Dory1.0 (4B)](https://llm-atlas-7or.pages.dev/models/dory1-0-4b.md) — NVIDIA, 2026-10-16 - [Nanbeige 4.2 (3B)](https://llm-atlas-7or.pages.dev/models/nanbeige-4-2-3b.md) — BOSS Zhipin, 2026-07-21 - [Ouro-Thinking (2.6B)](https://llm-atlas-7or.pages.dev/models/ouro-thinking-2-6b.md) — ByteDance, 2025-10-29 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/looped-depth-sharing/ Web page: https://llm-atlas-7or.pages.dev/concepts/looped-depth-sharing/ ## Concept: QK-Norm (QK-Norm) > RMSNorm applied to queries and keys before attention to keep logits well-behaved. Category: Positions & normalization Normalising queries and keys (usually before RoPE) prevents attention logits from growing too large, a common source of loss spikes in large-scale training.

Category: Positions & normalization Because a decoder's causal mask already prevents tokens from seeing the future, the model can infer order implicitly. NoPE layers omit RoPE entirely. Studies suggest this can help length generalisation. SmolLM3 removes RoPE from every fourth layer; Kimi K3 goes NoPE throughout. **Trade-off:** Potentially better extrapolation to longer contexts; less explicit positional signal. ## Models using NoPE (18) - [Mistral Large 4 (1T)](https://llm-atlas-7or.pages.dev/models/mistral-large-4.md) — Mistral AI, 2026-10-29 - [Recursive Flint (40B-A2.5B)](https://llm-atlas-7or.pages.dev/models/recursive-flint-40b-a2-5b.md) — Recursive, 2026-10-18 - [Reflection Beam (501B)](https://llm-atlas-7or.pages.dev/models/reflection-beam-501b.md) — Reflection, 2026-10-16 - [Muse Spark Open (816B-A42B)](https://llm-atlas-7or.pages.dev/models/muse-spark-open-816b-a42b.md) — Meta, 2026-10-15 - [Kolibri-1 (78B)](https://llm-atlas-7or.pages.dev/models/kolibri-1-78b.md) — Aleph Alpha, 2026-10-03 - [Ember-1 (2.8T)](https://llm-atlas-7or.pages.dev/models/ember-1.md) — Fireworks AI, 2026-09-23 - [GLM-5.3-Flash (320B)](https://llm-atlas-7or.pages.dev/models/glm-5-3-flash.md) — Z.ai, 2026-08-26 - [Muse Glimmer (30B)](https://llm-atlas-7or.pages.dev/models/muse-glimmer-30b.md) — Meta, 2026-08-10 - [Kimi K3 (2.8T)](https://llm-atlas-7or.pages.dev/models/kimi-k3.md) — Moonshot AI, 2026-07-27 - [Solar Open 2 (250B)](https://llm-atlas-7or.pages.dev/models/solar-open-2.md) — Upstage, 2026-07-22 - [Soofi S (30B-A3B)](https://llm-atlas-7or.pages.dev/models/soofi-s-30b-a3b.md) — SOOFI Consortium, 2026-07-10 - [North Mini Code (30B-A3B)](https://llm-atlas-7or.pages.dev/models/north-mini-code-30b-a3b.md) — Cohere, 2026-06-05 - [Command A+ (218B-A25B)](https://llm-atlas-7or.pages.dev/models/command-a-218b-a25b.md) — Cohere, 2026-05-20 - [Sarvam (105B)](https://llm-atlas-7or.pages.dev/models/sarvam-105b.md) — Sarvam AI, 2026-03-03 - [Tiny Aya (3.35B)](https://llm-atlas-7or.pages.dev/models/tiny-aya-3-35b.md) — Cohere, 2026-02-13 - [Arcee AI Trinity Large (400B)](https://llm-atlas-7or.pages.dev/models/arcee-ai-trinity-large-400b.md) — Arcee AI, 2026-01-27 - [Kimi Linear (48B-A3B)](https://llm-atlas-7or.pages.dev/models/kimi-linear-48b-a3b.md) — Moonshot AI, 2025-10-30 - [SmolLM3 (3B)](https://llm-atlas-7or.pages.dev/models/smollm3-3b.md) — Hugging Face, 2025-06-19 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/nope/ Web page: https://llm-atlas-7or.pages.dev/concepts/nope/ ## Concept: Cross-Layer KV Sharing (KV sharing) > Later layers reuse key/value states produced by earlier layers. Category: Efficiency & sharing GQA shares KV heads across query heads within a layer; cross-layer sharing goes further and lets whole layers reuse another layer's keys and values, so fewer layers add to the cache. Gemma 4 E2B and E4B are prominent examples of the idea from cross-layer attention research. **Trade-off:** Smaller cache and less compute for long contexts, with less per-layer flexibility. ## Models using KV sharing (4) - [Mistral Large 4 (1T)](https://llm-atlas-7or.pages.dev/models/mistral-large-4.md) — Mistral AI, 2026-10-29 - [DeepSeek V4.1-Flash (552B)](https://llm-atlas-7or.pages.dev/models/deepseek-v4-1-flash.md) — DeepSeek, 2026-09-10 - [Gemma 4 (E2B)](https://llm-atlas-7or.pages.dev/models/gemma-4-e2b.md) — Google, 2026-04-02 - [Gemma 4 (E4B)](https://llm-atlas-7or.pages.dev/models/gemma-4-e4b.md) — Google, 2026-04-02 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/kv-sharing/ Web page: https://llm-atlas-7or.pages.dev/concepts/kv-sharing/ ## Concept: Per-Layer Embeddings (PLE) > Each layer gets its own token-specific embedding signal from a large lookup table. Category: Efficiency & sharing Lookup tables are cheap to run and can live outside fast memory, so small models can store extra token-specific information per layer without making the transformer stack itself more expensive. It is why Gemma 4 E2B is described as 2.3B effective parameters but 5.1B including embeddings. The “E” stands for effective. **Trade-off:** More capacity for small on-device models at very low compute cost. ## Models using PLE (3) - [Qwen3.8-Flash-Next (125B-A6B)](https://llm-atlas-7or.pages.dev/models/qwen3-8-flash-next-125b-a6b.md) — Alibaba Cloud, 2026-08-26 - [Gemma 4 (E2B)](https://llm-atlas-7or.pages.dev/models/gemma-4-e2b.md) — Google, 2026-04-02 - [Gemma 4 (E4B)](https://llm-atlas-7or.pages.dev/models/gemma-4-e4b.md) — Google, 2026-04-02 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/per-layer-embeddings/ Web page: https://llm-atlas-7or.pages.dev/concepts/per-layer-embeddings/ ## Concept: Multi-Token Prediction (MTP) > Extra heads learn to predict several future tokens, and can draft tokens at inference. Category: Training objectives Besides the next token, small additional modules predict tokens further ahead. DeepSeek's version keeps a causal chain where each module conditions on the previous prediction. The extra targets give a denser training signal, and at inference the MTP modules act as a built-in draft model for speculative decoding. **Trade-off:** Denser training signal and faster decoding, for some extra parameters. ## Models using MTP (34) - [Nemotron 3.5 Super VL (120B-A12B)](https://llm-atlas-7or.pages.dev/models/nemotron-3-5-super-vl-120b-a12b.md) — NVIDIA, 2026-10-15 - [Ling 3.1 Flash (560B)](https://llm-atlas-7or.pages.dev/models/ling-3-1-flash.md) — InclusionAI, 2026-10-13 - [Xiaomi MiMo-V2.6-Flash-RL (309B)](https://llm-atlas-7or.pages.dev/models/xiaomi-mimo-v2-6-flash-rl-309b.md) — Xiaomi, 2026-09-21 - [Xiaomi MiMo-V2.6-Pro-RL (1.02T)](https://llm-atlas-7or.pages.dev/models/xiaomi-mimo-v2-6-pro-rl-1-02t.md) — Xiaomi, 2026-09-21 - [Step-5 Preview (600B)](https://llm-atlas-7or.pages.dev/models/step-5-preview-600b.md) — StepFun, 2026-09-20 - [Tencent Hy4-preview (770B-A49B)](https://llm-atlas-7or.pages.dev/models/tencent-hy4-preview-770b-a49b.md) — Tencent, 2026-08-28 - [GLM-5.3-Flash (320B)](https://llm-atlas-7or.pages.dev/models/glm-5-3-flash.md) — Z.ai, 2026-08-26 - [Qwen3.8-Flash-Next (125B-A6B)](https://llm-atlas-7or.pages.dev/models/qwen3-8-flash-next-125b-a6b.md) — Alibaba Cloud, 2026-08-26 - [Ornith 1.5 (35B-A3B)](https://llm-atlas-7or.pages.dev/models/ornith-1-5-35b-a3b.md) — Ornith, 2026-08-23 - [Qwen3.8 (27B)](https://llm-atlas-7or.pages.dev/models/qwen3-8-27b.md) — Alibaba Cloud, 2026-08-14 - [Nemotron 3.5 Lightning (30B-A3B)](https://llm-atlas-7or.pages.dev/models/nemotron-3-5-lightning-30b-a3b.md) — NVIDIA, 2026-08-11 - [Ling 3.0 Flash (124B)](https://llm-atlas-7or.pages.dev/models/ling-3-0-flash.md) — InclusionAI, 2026-08-04 - [Motif 3 Beta (314B)](https://llm-atlas-7or.pages.dev/models/motif-3-beta.md) — Motif Technologies, 2026-07-21 - [Inkling (975B)](https://llm-atlas-7or.pages.dev/models/inkling.md) — Thinking Machines Lab, 2026-07-15 - [DeepSeek V4-Flash (284B)](https://llm-atlas-7or.pages.dev/models/deepseek-v4-flash.md) — DeepSeek, 2026-04-24 - [DeepSeek V4-Pro (1.6T)](https://llm-atlas-7or.pages.dev/models/deepseek-v4-pro.md) — DeepSeek, 2026-04-24 - [Ling 2.6 (1T)](https://llm-atlas-7or.pages.dev/models/ling-2-6-1t.md) — InclusionAI, 2026-04-23 - [Tencent Hy3-preview (295B-A21B)](https://llm-atlas-7or.pages.dev/models/tencent-hy3-preview-295b-a21b.md) — Tencent, 2026-04-23 - [Xiaomi MiMo-V2.5 (310B)](https://llm-atlas-7or.pages.dev/models/xiaomi-mimo-v2-5-310b.md) — Xiaomi, 2026-04-22 - [GLM-5.1 (744B)](https://llm-atlas-7or.pages.dev/models/glm-5-1.md) — Z.ai, 2026-04-07 - [MiniMax M2.7 (230B)](https://llm-atlas-7or.pages.dev/models/minimax-m2-7-230b.md) — MiniMax, 2026-03-18 - [Nemotron 3 Super (120B-A12B)](https://llm-atlas-7or.pages.dev/models/nemotron-3-super-120b-a12b.md) — NVIDIA, 2026-03-11 - [MiniMax-M2.5 (230B)](https://llm-atlas-7or.pages.dev/models/minimax-m2-5-230b.md) — MiniMax, 2026-02-12 - [GLM-5 (744B)](https://llm-atlas-7or.pages.dev/models/glm-5-744b.md) — Z.ai, 2026-02-11 - [Step 3.5 Flash (196B)](https://llm-atlas-7or.pages.dev/models/step-3-5-flash-196b.md) — StepFun, 2026-02-01 - [GLM-4.7 (355B)](https://llm-atlas-7or.pages.dev/models/glm-4-7-355b.md) — Z.ai, 2025-12-22 - [Xiaomi MiMo-V2-Flash (309B)](https://llm-atlas-7or.pages.dev/models/xiaomi-mimo-v2-flash-309b.md) — Xiaomi, 2025-12-16 - [DeepSeek V3.2 (671B)](https://llm-atlas-7or.pages.dev/models/deepseek-v3-2.md) — DeepSeek, 2025-12-01 - [MiniMax M2 (230B)](https://llm-atlas-7or.pages.dev/models/minimax-m2-230b.md) — MiniMax, 2025-10-23 - [Qwen3 Next (80B-A3B)](https://llm-atlas-7or.pages.dev/models/qwen3-next-80b-a3b.md) — Alibaba Cloud, 2025-09-09 - [GLM-4.5 (355B)](https://llm-atlas-7or.pages.dev/models/glm-4-5-355b.md) — Z.ai, 2025-07-28 - [GLM-4.5-Air (106B)](https://llm-atlas-7or.pages.dev/models/glm-4-5-air.md) — Z.ai, 2025-07-28 - [DeepSeek R1 (671B)](https://llm-atlas-7or.pages.dev/models/deepseek-r1.md) — DeepSeek, 2025-01-20 - [DeepSeek V3 (671B)](https://llm-atlas-7or.pages.dev/models/deepseek-v3.md) — DeepSeek, 2024-12-26 Full explainer with figures by Sebastian Raschka: https://sebastianraschka.com/llm-architecture-gallery/mtp/ Web page: https://llm-atlas-7or.pages.dev/concepts/mtp/
