DeepSeek招土木工程师；腾讯参投！林俊旸深夜官宣新公司：做下一代AI智能体；宇树科技中签号出炉：共19414个丨雷峰早报

TL;DR - A Chinese tech-news daily digest covering AI industry moves: DeepSeek hiring civil/electrical engineers to build its own datacenter capability, Qwen's former tech lead Lin Junyang launching agent startup Pragmatik Labs (p7k), plus Anthropic watermarking Claude output and OpenAI's $7B tender offer at an $852B valuation.

• DeepSeek moves down the stack: job posts for IDC datacenter teams in Hangzhou, Beijing and Ulanqab span electrical, HVAC, automation, energy, comms and civil engineering — signaling a model company building its own compute infrastructure rather than renting it. It also opened a "DeepSeek Harness team" account, an internal code-agent effort benchmarked against Claude Code.
• Agent startups draw big money: Lin Junyang (ex-Alibaba Qwen tech lead) founded Pragmatik Labs in Shanghai to build "next-generation agents spanning digital and physical worlds," led by Gaorong and Sequoia China with Tencent participating; reported $2B pre-money, possibly >$5B next round. Separately, ex-Huawei "Genius Youth" Lou Yihang left to found Gravity Blueshift for a 200B+ parameter "embodied brain."
• Anthropic adds invisible text watermarks to Claude models released on/after Aug 2, framed as EU AI Act transparency compliance; watermarks survive copy-paste and possibly partial edits, with third-party detection tools planned.
• Other signals: Google reportedly shelved Gemini 3.5 Pro (ranked 8th on Artificial Analysis index) and may pivot to Gemini 4; SpaceX's ~$60B Cursor acquisition may retire the Cursor brand; miHoYo shut its AI-companion product BSide: Olivia Lin after under a month, citing inference cost and no monetization path.
