Z.ai Upgrades 700-Billion-Parameter GLM-5.3 for Coding as China’s Open-Weight AI Race Intensifies

Summary
GLM-5.3 will be released within two weeks with stronger coding capabilities, as Z.ai pushes a new flagship model aimed at narrowing the gap with Anthropic and OpenAI.
The upgrade stays on the same 700-billion-parameter base model used for June’s GLM-5.2, signaling faster iteration rather than a full rebuild; Z.ai has not yet published benchmark scores for the new version.
GLM-5.2 had already won attention for strong performance at lower cost, and Z.ai plans to publish GLM-5.3’s weights under a permissive license to attract developers and expand market share.
That opening comes as Chinese rivals gain ground: DeepSeek, Kimi and Alibaba’s Qwen have ranked highly, while DeepSeek just raised some V4 prices by as much as fourfold.
Z.ai’s shares once lifted its market value to $137 billion after GLM-5.2; even after falling to about $80 billion, the company remains a prominent player in the US-China AI contest.
