SakThai Coder 1.5B 💻

Code + tool-calling · Qwen2.5-Coder-1.5B fine-tune · Q4_K_M GGUF for CPU

The code specialist of the SakThai family — Qwen2.5-Coder-1.5B fine-tuned for tool-calling and shipped as a CPU-friendly GGUF. Part of the House of Sak. Read the story →

What it is

A Q4_K_M GGUF (1.07 GB) of Qwen2.5-Coder-1.5B-Instruct, QLoRA-fine-tuned on sakthai-combined-v6 so it can generate code and call tools. Runs on CPU via llama.cpp / Ollama.

Quick start

# via llama.cpp
wget https://huggingface.co/Nanthasit/sakthai-coder-1.5b/resolve/main/qwen2.5-coder-1.5b-instruct-q4_k_m.gguf
./llama-cli -m qwen2.5-coder-1.5b-instruct-q4_k_m.gguf -p "Write a Python function to merge two sorted lists:" -n 256 --temp 0.2

# via Ollama
ollama create sakthai-coder -f Modelfile   # FROM ./qwen2.5-coder-1.5b-instruct-q4_k_m.gguf
ollama run sakthai-coder "Write a script that monitors CPU usage"

For tool-calling, put function schemas in a <tools> block (ChatML format).

Benchmarks

Evaluation

Not independently benchmarked. Earlier versions of this card carried a model-index score derived from a small internal spot check (typically 5 or 8 hand-picked examples) presented as a benchmark result. Those entries have been removed rather than left to propagate through Hub metadata.

For tool-calling models in this family, the benchmark to use is sakthai-bench-v2 — 500 rows, balanced across simple / parallel / irrelevance, with held-out tools and multi-turn coverage. Results will be published here once this model has been run against it.
