Z.ai Open-Sources GLM-5.3 Weights for Agentic Coding and Cybersecurity
Z.ai has released the open weights of GLM-5.3, its strongest model, tuned for agentic coding and defensive cybersecurity. The weights can be downloaded, run locally, and fine-tuned for custom tasks — a full weight release rather than API-only access, so developers and researchers can inspect the model deeply and integrate it into their own pipelines.
