The Number

  • DeepSeek-Flash (DeepSeek-V4.1-Flash) lists at $0.15/M input, cache-miss, off-peak, with cache-hit input at $0.003/M, per DeepSeek's pricing docs as of 2026-09-14.
  • Qwen3-max sits at 2.5 yuan/M input for prompts under 32K tokens, its cheapest tier, per Alibaba DashScope pricing as of 2026-09-14.
  • qwen3.7-flash prices at $0.03/M input on OpenRouter, the cheapest China-lab model on the platform as of 2026-09-14.

Top of the Fold

  • Zhipu closes roughly $5B in funding for its next-gen GLM base model, full self-training, and compute buildout, a war chest that keeps it in the frontier-scale conversation, per 雷峰网.
  • ByteDance ships the consumer version of its Doubao phone assistant with cross-app task execution, debuting on the Nubia NaviX Ultra on 9月16日, moving the phone-agent fight from chat to getting things done, per 智东西.
  • DeepSeek is circling 高瓴's 90s-born partner 严文韬 as CFO, its first heavyweight non-technical hire, a signal it is staffing up as an IPO track forms, per 智东西 citing TOP华人科创社 (circulating/unconfirmed).

Untranslated

  • 夕小瑶's team hands-on-tested five domestic world models and found all of them still research-preview only, with no real consumer entry point despite a dozen teams shipping demos, one editor's read as recorded by 夕小瑶科技说.
  • Ant's AI Safety Lab shipped SingProbe, an inline guardrail that flags risk as the model generates rather than after, pitched at cutting the latency cost of external review, per 雷峰网 (company-stated).
  • 具脑磐石 released Cog-WM 1.0, billed as the first brain-inspired latent-space predictive world model, claiming SOTA-beating navigation without prebuilt maps, per 雷峰网 (company-stated, unverified).
  • Otherwise quiet across the Chinese community overnight.

The Backstory

  • The $399 Microduck robot duck going viral on X is built in Shenzhen by 潘昊's Seeed Studio, the same shop that manufactured Hugging Face's Reachy Mini, and 潘昊's read is the signal is not the hardware but what it lets someone build next, per 极客公园.

The Kicker

  • 太乙圣莲 is proposing to spend 3 billion yuan to revive bankrupt Neta Auto, prompting Chinese commenters to joke that saving Neta (哪吒) really does take 太乙真人, per 雷峰网.
