Chinese startup Z.ai has launched GLM-5.2, a powerful AI model for complex coding projects. This new large language model boasts a massive 1 million token context window, allowing it to handle extensive software development tasks. GLM-5.2 is available under an open-source license, offering an alternative to proprietary AI systems. It performs strongly on industry benchmarks, rivaling top closed-source models.

Move underscores a trend of Chinese players seeking to capture users displaced by rising prices for top models from US rivals.

Z.ai released GLM-5.2 with a usable 1-million-token context window across all GLM Coding Plan tiers; MIT weights pending.
