Z.ai Launches GLM-5.2 With a Usable 1M-Token Context, Two Thinking-Effort Levels, and No Benchmarks at Launch

Zhipu AI has released GLM-5.2, an open-source model featuring a one-million-token context window and two selectable tiers for processing effort. The update is now accessible across the company's coding platforms via an Anthropic-compatible API, allowing developers to integrate the model into existing workflows. While the release lacks performance benchmarks, the increased context capacity enables users to process significantly larger datasets in a single prompt. This development provides engineers with an alternative for managing extensive codebases and complex documents using established development tools.
