OpenThaiGPT 1.5 7B — GGUF

Official GGUF quantizations of openthaigpt/openthaigpt1.5-7b-instruct

Website · Discord · Paper

</div>

The smallest OpenThai model and the easiest place to start — a 7B Thai chat model that runs on a laptop. Fine-tuned on over 2,000,000 Thai instruction pairs, with multi-turn conversation, RAG and tool-calling support.

If you want reasoning, use R1 32B. If you want Thai law, use OpenThai 2.0 Legal.

Usage

Ollama

ollama run hf.co/openthaigpt/openthaigpt1.5-7b-instruct-GGUF:Q4_K_M

llama.cpp

llama-cli -m openthaigpt1.5-7b-instruct.Q4_K_M.gguf \
  -p "ช่วยสรุปข้อดีข้อเสียของรถยนต์ไฟฟ้าในบริบทประเทศไทย" -n 2048 --temp 0.7

This model uses the ChatML template (<|im_start|> / <|im_end|>), embedded in the GGUF. Recommended sampling: temperature=0.7, top_p=0.9.

Capabilities

• Multi-turn conversation
• Retrieval-Augmented Generation — pair with OpenThaiRAG
• Tool calling
• Up to 131,072 input tokens in the full-precision model

Limitations

At 7B this is the least capable model in the family — it trades accuracy for the ability to run anywhere. For anything where correctness matters more than convenience, use a larger model. Not safety-tuned for open consumer deployment without your own guardrails.
