Z.AI has released GLM-5.2, an open-source model with a 1M-token context window under an MIT license. On FrontierSWE, a long-horizon coding benchmark, GLM-5.2 trails Claude Opus 4.8 by 1% while outperforming GPT-5.5 by 1%, and achieves 81.0 on Terminal-Bench 2.1 compared to Opus 4.8's 85.0.

Z.ai has released GLM-5.1, a 754-billion parameter open-weight model matching the size of its predecessor GLM-5. The model demonstrates improved ability to generate complex, multi-part outputs like HTML pages with SVG graphics and CSS animations, available via Hugging Face and OpenRouter.

Z.ai has released GLM-5V Turbo, a native multimodal foundation model designed for vision-based coding and agent-driven tasks. The model supports image, video, and text inputs with a 202,752 token context window, priced at $1.20 per million input tokens and $4 per million output tokens.
