Qwen3.6-27B-Fable-Uncensored
Unrestricted - Agentic - Reasoning - Tool-Calling
Qwen3.6-27B-Fable-Uncensored is an unrestricted 27B agentic model that reasons step-by-step and operates tools across multi-turn sessions, while delivering top-tier general knowledge. It is a refusal-reduced (abliterated) variant of lemuralabs/Qwen3.6-27B-Fable-Agentic.
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% | 97.67% |
| GPQA-Diamond (198 Q) | 57.58% | 56.57% |
Uncensored at no cost to quality. Removing refusals left capability fully intact: it matches the aligned model on MMLU-Pro (88.29%), GSM8K, and hard GPQA-Diamond reasoning (56.57% vs base 57.58%, within noise) - and still beats the base on knowledge.
| Category | Base | This model |

Highlights
- Unrestricted - refusal behavior removed; declines far fewer requests
- Top-tier knowledge - 88.29% MMLU-Pro, above the base, with zero abliteration tax
- Strong math - 97.67% GSM8K
- Agentic tool-calling + step-by-step reasoning
Responsible use
This model has had refusal behavior reduced, so it may produce content a safety-tuned model would decline. You are responsible for how you use it - use it lawfully and ethically, in accordance with the base-model and dataset licenses. It is not intended for producing harmful, illegal, or abusive content.
Capabilities
- Unrestricted, agentic multi-turn tool-calling
- Chain-of-thought reasoning
- Top-tier general knowledge and math
- Multimodal (vision + text) architecture
Usage (vLLM)
vllm serve lemuralabs/Qwen3.6-27B-Fable-Uncensored --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.
