## 🚀 Major Updates
- **WeChat's native AI assistant 'Xiao Wei' begins grayscale testing** [3]: First-ever deep system-level integration of AI capabilities—eliminating reliance on third-party OCR/screen-reading solutions
- **Tsinghua University open-sources Spatial-TTT, a spatial intelligence model accepted to ECCV 2026** [6]: Leverages test-time training (TTT), achieving superior performance over GPT-5 and Gemini-3-pro on long-video spatial understanding tasks—despite using only 2B parameters
- **DeepSeek's Harness division urgently recruits full-stack Agent engineers** [4]: Lead engineer Cui Tianyi publicly posted recruitment ads, emphasizing that Harness serves as the critical middleware layer for building Agents—distinct from foundation models themselves
- **Alibaba's Joseph Tsai reaffirms AI strategy in VivaTech keynote** [5]: Projects the global AI market to reach **$50 trillion**, urging China to significantly ramp up investment in foundational infrastructure—including chips and open-source models
- **Optical communications stocks enter historic bull run** [7]: Fueled by surging fiber-optic demand from North American AI data centers, Longfly Optical Fiber & Cable's Hong Kong-listed shares have surged over **15× in one year**
- **Third-party AI products face business model crises** [8]: High costs tied to official API dependencies are pushing developers toward local Claude Code deployments or self-hosted proxy services as viable alternatives
- **Motorola Razr Fold pivots focus to international markets** [0]: Though hardware specs lead competitors, its rough near-stock Android experience and premium pricing hinder traction in China's mainstream market
