# aksarallm-1.5b-v2-checkpoint

Earlier 1.5B Qwen2-based Indonesian checkpoint. Superseded by
[`AksaraLLM/AksaraLLM-Qwen-1.5B-v5-public`](https://huggingface.co/AksaraLLM/AksaraLLM-Qwen-1.5B-v5-public)
which has measurably better perplexity and lower English leak.

## Measured baseline (Devin audit, CPU bf16, 50 short Indonesian sentences)

| Metric | Value |
|---|---|
| Perplexity | **9.9** (vs 8.4 for v5-public) |
| English-stopword ratio in ID-prompted output | 3.6% (vs 0.9% for v5-public) |
| Indonesian-stopword ratio in ID-prompted output | 26.8% |
| Parameters | 1777.1 M |
| Architecture | Qwen2ForCausalLM |

## Status

Kept for historical reference / reproducibility. **For new downstream work,
use `AksaraLLM-Qwen-1.5B-v5-public` instead.**
