Z.ai launched GLM-5.2 with a 1 million-token context window, new reasoning controls, and support for long-horizon coding tasks across entire codebases. The company made the model available immediately to Coding Plan users and plans to release API access, chatbot support, technical details, and MIT-licensed open weights the following week. Z.ai positions GLM-5.2 as a coding-first upgrade focused on agentic software engineering, though it did not publish benchmark results at launch.
