Who shipped

Zhipu/Z.ai shipped GLM-4.5. Alibaba shipped Wan2.2. SenseTime shipped Wu Neng. China MFA shipped a Governance Action Plan.

Open-source pulse

GLM-4.5 + Wan2.2 + earlier Qwen3-Coder/Qwen3-235B-Thinking + Tencent Hunyuan3D World 1.0 amounts to the largest Chinese open-source release wave of the year, timed precisely to WAIC. All major Chinese labs released under permissive licenses (MIT/Apache 2.0).

Money, infra & hardware

Huawei unveiled CloudMatrix 384 / Atlas 900 A3 SuperPod at WAIC — 384 Ascend 910C chips linked into China’s largest-ever AI supercluster, positioned as a system-level rival to NVIDIA’s GB200 NVL72 (72 GPUs). Huawei’s bet: out-scale at the cluster level even while trailing per-chip. via DigiTimes

Quiet corners

WAIC showcased 150+ humanoid robots — China’s biggest ever — with 60+ global debuts and 80+ embodied-intelligence companies. Robot boxing matches and a Beijing-developed industrial multi-task humanoid debuted. America’s AI Action Plan reverberated through WAIC as the explicit backdrop. US frontier labs absent from stage — Anthropic’s Dario Amodei has been publicly lobbying for stricter China export controls. Mistral wrapped July with a code-completion model + “AI for Citizens” public-sector initiative with France’s army and job agency, plus Luxembourg’s government.

By the numbers

  • 355B / 32B / 106B / 12B — GLM-4.5 / GLM-4.5-Air total / active params
