Z.ai is the AI assistant and model platform of the GLM model family. In the web chat (chat.z.ai) it answers questions, writes and debugs code, builds websites and slides, and runs longer agent tasks with the current GLM-5.3 models. Developers use the same models through the Z.ai API or the GLM Coding Plan inside coding agents such as Claude Code, Codex, OpenCode, Cline and OpenClaw. Many GLM models are released as open weights on Hugging Face (for example GLM-5.3-Flash under the MIT license), so they can also be run on your own hardware.
