✨Key takeaways:
SPAR: align RL credit to where decisions happen — optimize stage-wise, not via one noisy end reward.
Fact-Aware RL: verify atomic claims with retrieval → make hallucination measurable & optimizable🧐
Rubric Evolution: auto-mine & patch adversarial reward hacks.

We have officially open-sourced the new-generation medical LLM Baichuan-M3, which scored 65.1 on HealthBench and claimed the championship with 44.4 on HealthBench Hard. It has comprehensively outperformed GPT-5.2 across the board in the medical field. @OpenAI @claudeai

[Baichuan AI @BaichuanAI]

Evaluation shows that the medical hallucination rate of M2 Plus is significantly lower than that of general LLMs, about three times lower than DeepSeek.

Now it’s available on web (https://t.co/ouTDSkFvsK) and in mobile app stores.

[Baichuan AI @BaichuanAI]

We have just launched our enhanced evidence-based medical model, Baichuan-M2 Plus, while simultaneously upgrading its supporting application Baixiaoying and opening the API.
