Official GGUF quantizations of iapp/openthai2.0-legal-thaillm-nemotron-3-nano-30b-a3b

Website · Announcement · Live demo · Discord

An open-weight Thai legal LLM that recalls Thai statutes and cites the exact law name and section (มาตรา) as structured JSON. 30B Mixture-of-Experts with only ~3B parameters active per token — which is why a 30B model runs comfortably on modest hardware.

Use it with retrieval. Open-book citation accuracy is 0.99 versus 0.07–0.40 from pure memory. Pair it with OpenThaiRAG or your own retrieval over authoritative statute text.

The chat template is embedded in the GGUF. Recommended sampling: temperature=0.3, top_p=0.9. Architecture is a hybrid Mamba2-Transformer MoE (NVIDIA Nemotron-3-Nano-30B-A3B base) — use a recent llama.cpp build.

⚠️ Responsible use

Outputs are decision support, not legal advice. Verify every citation against the current statute text. Near-miss rejection — telling the governing section from a closely related one — is the hardest task for every model tested, this one included.
