OpenThaiGPT R1 32B — GGUF

Official GGUF quantizations of openthaigpt/openthaigpt-r1-32b-instruct

Website · Discord · Paper

</div>

A Thai reasoning model that shows its work — and beats 70B models at less than half their size. These are the official quantizations, built from the source weights by the OpenThai team.

Quants

Usage

llama.cpp

llama-cli -m openthaigpt-r1-32b-instruct.Q4_K_M.gguf \
  -p "อธิบายความแตกต่างระหว่างสัญญาซื้อขายกับสัญญาเช่าซื้อ" \
  -n 4096 --temp 0.6 --top-p 0.95

Ollama

ollama run hf.co/openthaigpt/openthaigpt-r1-32b-instruct-GGUF:Q4_K_M

⚠️ Chat template

This model uses the DeepSeek-R1 template (<｜User｜> / <｜Assistant｜>), not ChatML. Serving it with ChatML produces degraded output that looks superficially correct. The template is embedded in these GGUF files, so llama.cpp and Ollama pick it up automatically — but if you build your own prompt string, use the DeepSeek format.

Recommended sampling: temperature=0.6, top_p=0.95, top_k=40. The upstream card recommends no system prompt for this model.

Benchmarks

Quantization costs some accuracy; these figures are from the full-precision model.
