Qwen3.6-27B-Fable-Agentic
Agentic - Reasoning - Tool-Calling - Top-Tier Knowledge
Qwen3.6-27B-Fable-Agentic is a powerful 27B agentic model that reasons step-by-step and operates tools across multi-turn sessions, while delivering top-tier general knowledge. Fine-tuned from Jackrong/Qwopus3.6-27B-v2.
Benchmarks
Evaluated head-to-head against the base model on identical questions, with an 8192-token budget so step-by-step reasoning is never truncated.
| Benchmark | Base | This model |
|---|---|---|
| MMLU-Pro (350 Q) | 86.86% | 88.29% |
| GSM8K (300 Q) | 98.00% | 97.33% |
| GPQA-Diamond (198 Q) | 57.58% | 57.07% |
Knowledge improved, hard reasoning preserved: +1.43 over base on MMLU-Pro, matching it on GSM8K math and on GPQA-Diamond (graduate-level science, ~frontier-class for a 27B) - with agentic tool-calling added on top.

Usage (vLLM)
vllm serve lemuralabs/Qwen3.6-27B-Fable-Agentic --trust-remote-code --reasoning-parser qwen3 --enable-auto-tool-choice --tool-call-parser qwen3_coder --max-model-len 16384
Tip: this model reasons before answering - give it a generous max_tokens so it can finish its chain of thought.
