> Small dense Llama baseline in the Qwen comparison, with fewer layers but more width.

| Property | Value |
| --- | --- |
| Lab | Meta (United States) |
| Released | 2024-09-25 |
| Decoder type | Dense |
| Family | Dense |
| Scale | 1B parameters |
| Context window | 128,000 tokens |
| Attention | GQA |
| Layer mix | 16 GQA |
| KV cache / token (bf16) | 32 KiB (Low) |

**Key detail:** Wider architecture with more heads than Qwen3 0.6B.

## Architecture concepts

- [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.

## Benchmark (Artificial Analysis Intelligence Index)

- AA Intelligence Index v4.3.2: total 4.8 (Scientific 2.7)
