The Number

Top of the Fold

  • Lenovo's self-built code agent TianxiCode tops SWE-bench-Live at a 71% resolve rate, putting a hardware house at the front of the agent-coding board, per 量子位.
  • DiffuSpace closes two rounds totaling several hundred million yuan, the largest diffusion-LLM raise on record, led by Matrix, Shunwei and Legend Capital with Huawei Hubble following, per 智东西.

Untranslated

  • Shenzhen's Kunwei Technology raises 400M yuan led by XVC and Sequoia China to build low-frequency ultrasound that images through the skull in real time, framed by its founder as the brain-science equivalent of Nvidia, per 极客公园.
  • ByteDance researchers trace DeepSeek's uneven answers to token position in the prompt rather than the question itself, circulating as a reproducibility finding, per 量子位.
  • Tsinghua-linked 星动纪元 claims the top embodied-model spot by decoupling video prediction from action learning rather than training them together, company-stated, per 量子位.
  • openJiuwen open-sources an enterprise AgentOS pitched at multi-agent coordination with self-evolution, a drop not a capability proof, per 量子位.
  • Otherwise quiet across the Chinese community overnight.

The Backstory

  • Tian Keyu, the Peking University PhD once sued by ByteDance in the 2024 intern-sabotage case who also took a NeurIPS 2024 best-paper award, has quietly raised near $30M at a $2B valuation from Wuyuan and IDG for a 10-person world-model lab, per 雷峰网.

The Kicker

  • GeekPark spent ten days living with Today AI, a China personal-assistant app from Teambition founder 齐俊元, after noting the US versions all speak Gmail and Slack and go mute on domestic apps, per 极客公园.
