The latest AI news and updates of Zhipu AI — AI lab behind the GLM model series and the Z.ai developer platform. Covering Zhipu AI's latest launches and product updates from the past 90 days.
Zhipu AIAug 28Z.ai released the open weights for GLM-5.3, its most capable model for agentic coding and cyber defense. The model is now available to download, run, and customize on Hugging Face. This release follows the completion of safety evaluation and hardening, fulfilling the commitment to publish the weights two weeks after the initial launch.
Zhipu AIAug 27Z.ai will release the open weights for its GLM-5.3 model on Hugging Face tomorrow, August 28, 2026. The model provides frontier coding performance and emergent cyber defense capabilities, including vulnerability discovery. This release makes the model weights publicly available for local deployment and self-hosting.
Zhipu AIAug 14Z.ai launched GLM-5.3, an open model post-trained on a 743B parameter base model. It delivers improved coding and agentic performance alongside emergent cyber defense capabilities, including vulnerability discovery. The model is available now through the GLM Coding Plan and ZCode, with open weights scheduled for release in two weeks.
Zhipu AIAug 11Z.ai reached 1 million users for its ZCode agentic coding harness. The platform reset usage limits for all GLM Coding Plan subscribers as a community thank-you. A new update improves engineering workflow intelligence and achieves a 98% cache hit rate, delivering approximately 1.8 times more usage capacity for the same computational resources.
Zhipu AIJul 1Z.ai launched ZCode, an official development environment optimized for the GLM-5.2 model. The desktop application supports long-horizon task planning, remote bot control, and multi-agent collaboration. GLM Coding Plan subscribers receive a 1.5x usage quota, and the environment supports bring-your-own-key configurations. ZCode is available now for macOS, Windows, and Linux.
Zhipu AIJun 19Z.ai is offering free inference for its GLM-5.2 model through Hugging Face Inference Providers for a five-hour window. Hugging Face is covering the costs across five providers, including Zai, Together AI, Novita, Fireworks, and DeepInfra. The model is available for immediate use through these platforms without setup or payment.
Zhipu AIJun 15Z.ai released GLM-5.2, a flagship coding model featuring a 1-million-token context window and two thinking-effort levels. The model is available immediately to all GLM Coding Plan users, with Max effort recommended for complex coding tasks. API services and an MIT-licensed open-source release follow next week.
