UltraThinker-1.7b 🧠

UltraThinker-1.7b is a fine-tuned version of Qwen/Qwen3-1.7B designed to improve reasoning and output quality. Compared to the base 1.7 billion-parameter model, it’s optimized to “think better” — meaning it produces more coherent, context-aware responses and shows stronger problem-solving and understanding skills in general-purpose tasks.

• Increasing the context window seems to improve the model's performance.
