Jackrong/Qwen3.5-9B-Claude-4.6-Opus-Reasoning-Distilled-v2

This model is the second iteration of a 9 billion parameter Qwen3.5 fine-tune by Jackrong, engineered to significantly enhance the efficiency and accuracy of chain-of-thought reasoning. It was trained using 14,000 Claude 4.6 Opus-style general reasoning samples, with a focus on distilling concise and reusable reasoning patterns rather than just maximizing raw benchmark scores.

Key Capabilities & Differentiators

  • Efficient Reasoning: Drastically improves reasoning speed and reduces token consumption (over 20% fewer characters/tokens) while increasing absolute accuracy.
  • General Reasoning Scaffold: Primarily trained on general-domain reasoning data (mathematics, word problems, logical deduction, general knowledge), leading to a robust and transferable reasoning logic.
  • Cross-Task Generalization: Achieves high performance on HumanEval and HumanEval+ benchmarks, demonstrating strong generalization despite not being code-centric in training.
  • Optimized for Economy: Explicitly designed to trim overhead from verbose reasoning, making it ideal for scenarios where reasoning efficiency per unit of inference budget is crucial.

Good For

  • Resource-constrained local deployment: Reduces latency and memory pressure on consumer GPUs or lower-memory setups.
  • Agentic workflows: Improves throughput and lowers cumulative inference costs in multi-step agent systems.
  • Open-source tool use and agent stacks: Highly practical for lightweight reasoning systems and autonomous agent projects.
  • Offline analytical tasks, coding, math, and heavy logic-dependent prompting: Provides transparent internal logic for users to follow.
