# Ling 2.6 (1T)

> Ling 2.5 successor that keeps the Lightning Attention and MLA hybrid stack while adding an MTP layer for multi-token prediction.

| Property | Value |
| --- | --- |
| Lab | InclusionAI (China) |
| Released | 2026-04-23 |
| Decoder type | Sparse hybrid |
| Family | Hybrid MoE |
| Scale | 1T total, 63B active (6.3% active) |
| Context window | 262,144 tokens |
| Attention | Lightning Attention plus MLA |
| Layer mix | 10 MLA + 70 Lightning Attention + 1 MTP layer |
| KV cache / token (bf16) | 11.2 KiB (Very low) |

**Key detail:** Keeps the 7:1 linear-attention/MLA ratio and adds one multi-token-prediction layer for speculative decoding.

## Architecture concepts

- [Multi-Head Latent Attention (MLA)](https://llm-atlas-7or.pages.dev/concepts/mla.md): Keys and values are compressed into a small latent vector that is cached instead of full K/V.
- [Hybrid Attention (Hybrid attention)](https://llm-atlas-7or.pages.dev/concepts/hybrid-attention.md): Mixes cheap linear-attention or state-space layers with a few full-attention layers.
- [Multi-Token Prediction (MTP)](https://llm-atlas-7or.pages.dev/concepts/mtp.md): Extra heads learn to predict several future tokens, and can draft tokens at inference.
