Zhipu AI to Open Source GLM-5.2 Under MIT License: Million-Token Usable Context, Free for All Commercial Use

On June 13, Zhipu AI announced its latest GLM-5.2 large model is now fully available to GLM Coding Plan subscribers, and will be fully open sourced under the MIT license next week with free commercial use across all scenarios. Positioned as Zhipu's most capable open-source model to date, its core highlight is a genuinely usable 1 million token context window, excelling at long-document understanding, codebase analysis and long-cycle agent tasks. The announcement comes amid US export controls on Anthropic's flagship models; Zhipu stated "cutting-edge intelligence should not belong only to a few, nor be revoked at will by a few rules", widely interpreted as a counter-openness strategy amid global AI restrictions. The model will launch simultaneously on Hugging Face and ModelScope, expected to dramatically lower barriers for global developers to access top-tier large models.
