GLM-5.2 is the current flagship language model from Zhipu AI (internationally known as Z.ai), released on June 13, 2026 under an MIT license as an open-weight model. It is built on a Mixture-of-Experts architecture with approximately 744–753 billion total parameters and around 40 billion active parameters per token. The model is primarily designed for long-horizon coding tasks, agent-based workflows, and software engineering, featuring a usable 1-million-token context window. It achieves 62.1% on SWE-bench Pro as the strongest open-weight model, trailing Claude Opus 4.8 (69.2%) but surpassing GPT-5.5 (58.6%).
