Model overview

Qwen3.5-2B-Claude-4.6-Opus-Reasoning-Distilled-GGUF is a compact reasoning model built on the Qwen3.5-2B architecture and trained through knowledge distillation from Claude-4.6 Opus. The model learns to structure its thinking process using formatted <think> tags before generating final responses, enabling transparent step-by-step problem solving in a lightweight package. Unlike its larger counterpart, the 27B version, this 2B model prioritizes efficiency while maintaining reasoning capabilities through distillation of high-quality reasoning trajectories. The model was enhanced with additional reasoning data from Jackrong/Qwen3.5-reasoning-700x, introducing superior reasoning patterns across science, instruction-following, and mathematics domains.


Model inputs and outputs

The model accepts text prompts and generates responses prefixed with structured reasoning blocks. It operates within a 16,384 token context window, allowing complex multi-step reasoning to fit comfortably in memory. The model outputs follow a consistent format with internal thinking presented in `` tags followed by a final answer, making its decision-making process transparent and verifiable.


Inputs

- Text prompts of variable length up to 16,384 tokens

- Problem statements requiring analytical or mathematical reasoning

- Code-related questions and debugging requests

- Instruction-following tasks with multiple steps or constraints


Outputs

- Structured thinking blocks enclosed in `` tags showing step-by-step reasoning

- Final answers following the reasoning process

- Formatted solutions for coding, math, and logic problems


Capabilities

The model demonstrates modular and structured thinking inherited from Opus-level reasoning patterns. It parses user prompts with confidence and establishes outlined plans in its thinking block rather than engaging in exploratory trial-and-error. The model excels at breaking down complex problems into clearly defined subcomponents, evaluating constraints and edge cases, and executing reasoning chains sequentially. Training focused on response-only optimization strengthened the model's ability to generate efficient reasoning trajectories that avoid excessive transitional or repetitive thinking on simpler queries. The 2B architecture still maintains analytical depth while reducing inference time compared to larger models.


What can I use it for?

This model suits offline analytical tasks where you need to follow the AI's reasoning transparently. Use it for math problem solving, coding tasks, logical deduction, and instruction-following scenarios that benefit from step-by-step breakdown. Students and researchers can leverage it for learning purposes and academic exploration. Content creators building explanation-heavy tools can integrate it to show working through problems. Since it is a test version intended for learning and demonstration, developers should reserve it for academic research and technical exploration rather than production systems. The related 14B reasoning model offers an alternative for scenarios demanding higher reasoning capacity.


Things to try

Test the model on problems where intermediate steps matter more than the final answer, such as explaining mathematical proofs or walking through debugging processes. Feed it questions requiring constraint evaluation and multi-part solution planning to see how it structures reasoning across domains. Try comparing its thinking blocks across simple versus complex queries to observe how it scales reasoning effort efficiently. Experiment with prompts in science and instruction-following domains since the model received specific enhancement training on these areas. Check how well it handles reasoning consistency when given partially specified problems or scenarios with implicit constraints.
