GLM-5.2

Z.ai's coding-first GLM with a usable 1M-token context and High and Max effort levels. Exclusive to the GLM Coding Plan at launch, with a standalone API and MIT open weights promised to follow.

Z.ai published no benchmark scores at launch, so GLM-5.2 is not on our leaderboards yet and any 'beats X' comparison circulating online is an estimate, not measured data. It is also not on OpenRouter, and Z.ai expects the standalone API and the MIT open weights to land the week after the June 13 launch.
