Z.ai releases GLM-5.2 with 1M context window, beats GPT-5.5 on coding

By PulseAugur Editorial · [1 sources] ·

Z.ai, the international arm of Zhipu AI, has released GLM-5.2, a 753B parameter Mixture-of-Experts model. This new model boasts a stable 1 million token context window, a significant increase from its predecessor, and is MIT-licensed with open weights available on Hugging Face. GLM-5.2 has demonstrated superior performance on coding benchmarks, outperforming GPT-5.5 on SWE-bench Pro, and offers competitive pricing for its API and subscription plans, making it a potentially more cost-effective alternative to models like Claude Opus. AI

IMPACT This release offers a significantly larger context window and competitive pricing, potentially enabling more complex coding tasks and agentic workflows.
