While the model size corresponds to an SLM (Small Language Model), it achieves performance on multi-turn tasks comparable to Gemini 2.5 Flash and GPT-4o. It significantly improves upon the original Qwen3-8B, recording MT-Bench 9.08 and JMT-Bench 8.87 scores.

It supports parallel processing of deep-thinking prompts using our Deep-Think technique and is compatible with the OpenAI API via vLLM deployment.

Although it was initially planned as a closed model for API-based access, we have decided to release it as an open model in light of our new policy to monetize only after further accuracy improvements.

BenchMark

Based on repeated evaluations of frequent outputs at temperatures 0.2 and 0.6, conducted on May 13, 2025, using GPT-4o and Gemini 2.5 Flash as judges. All tests were performed internally on a single A40 GPU. Results may vary under external or official benchmark conditions.

How to use:

Runs on a single A40 GPU.
