# Sarvam (105B)

> Larger Sarvam variant keeps the sparse MoE layout but switches from GQA to MLA.

| Property | Value |
| --- | --- |
| Lab | Sarvam AI (India) |
| Released | 2026-03-03 |
| Decoder type | Sparse MoE |
| Family | Sparse MoE |
| Scale | 105B total, 10.3B active (9.8% active) |
| Context window | 131,072 tokens |
| Attention | MLA with KV LayerNorm and NoPE + RoPE |
| Layer mix | 32 MLA |
| KV cache / token (bf16) | 36 KiB (Low) |
| License | Apache License 2.0 |

**Key detail:** Large vocabulary and strong Indic language support carried into the larger MLA-based sparse MoE variant.

## Architecture concepts

- [No Positional Embeddings (NoPE)](https://llm-atlas-7or.pages.dev/concepts/nope.md): Some or all layers drop explicit positional encodings and rely on the causal mask.
- [Grouped-Query Attention (GQA)](https://llm-atlas-7or.pages.dev/concepts/gqa.md): Several query heads share one key/value head, shrinking the KV cache with little quality loss.
- [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.
- [Mixture of Experts (MoE)](https://llm-atlas-7or.pages.dev/concepts/moe.md): Many feed-forward experts, but a router sends each token to only a few of them.
