Readme

refinedneuro/vibethinker-3b-hermes

A 3B reasoning model that calls tools. A LoRA fine-tune of WeiboAI/VibeThinker-3B (Qwen2-based) that adds Hermes-style function calling (<think>…</think> + <tool_call>…</tool_call>) while preserving its math/STEM reasoning.

Run

ollama run refinedneuro/vibethinker-3b-hermes

Tags

latest (=Q6_K), Q6_K, Q8_0, f16

Quant note. This is a tool-calling model, and quantization below Q6_K degrades tool-call fidelity (Q3/Q4/Q5 emit malformed/incomplete calls and can loop). For that reason the Q3_K_M / Q4_K_M / Q5_K_M tags now point to the Q6_K build — pulling any of them gives you the smallest good-quality model. Use Q6_K or higher; default latest = Q6_K.

Recommended settings (baked in)

temperature 0.6 · top_p 0.95 · repeat_penalty 1.1 · stops on <|im_end|>. For reliable single tool calls, also stop on </tool_call>.

Benchmarks (summary)

  • Reasoning (AIME 2024): base avg@4 0.842 → this model 0.783; pass@4 0.867 unchanged.
  • Tool-calling (BFCL single-turn, with stop fix): simple ~60%, multiple ~31%, relevance 87.5%.

Known limitations

Over-eager to call tools; can fall into repetition loops on out-of-distribution multi-turn input. Not production-ready. See the full model card: https://huggingface.co/RefinedNeuro/VibeThinker-3B-Hermes
