Details

Chinese AI lab Z.ai has released a new large language model, GLM-5.1. This is a massive model with 754B (75.4 billion) parameters, weighing in at 1.51TB, and is an open-weight model released under the MIT License.

GLM-5.1 emphasizes its ability to perform Long-Horizon Tasks, and excels at generating animations that combine complex HTML, CSS, and SVG. Notably, when the code generated by the model contains errors, it has demonstrated excellent self-correction ability, precisely identifying the cause of the problem (e.g., a conflict between CSS transform and SVG attribute) and immediately rewriting code to resolve it.
