Qwen3.6-27B-Fable-Agentic

Agentic - Reasoning - Tool-Calling - Top-Tier Knowledge

Beats its base model on knowledge - and acts like an agent.

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.

MMLU-Pro by category

Category	Base	This model
Biology	96.0%	94.0%
Business	78.0%	88.0%
Chemistry	84.0%	80.0%
Computer Science	84.0%	84.0%
Health	82.0%	86.0%
Math	94.0%	94.0%
Physics	90.0%	92.0%
Overall	86.86%	88.29%

Highlights

Top-tier knowledge - 88.29% MMLU-Pro, above the base model
Strong math - 97.33% GSM8K
Agentic tool-calling across multi-turn sessions
Step-by-step reasoning built in

Capabilities

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-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.
