A strong coding model at budget prices

GLM is a popular choice for Claude Code-style agents because it follows the Anthropic tool-use format well. Here it runs on the same Anthropic-compatible endpoint, so you can switch Claude Code to GLM with one environment variable.

Our prices are shown next to Z.ai's published list price, up to 72% below it on a blended basis.

Uncensored variants available

Community fine-tunes with fewer refusals (GLM Uncensored and Abliterated) are available on the same key for writing, research and red-teaming within our acceptable-use rules.

Questions

More answers in the docs, or contact us.

Can I use GLM inside Claude Code?+

Yes. Set ANTHROPIC_BASE_URL to our endpoint and ANTHROPIC_MODEL to a GLM model id from the table.

Is GLM Flash good enough for production?+

For high-volume tasks like summarising, tagging and extraction it is excellent value. Use GLM-5.3 when quality matters more than cost.

Do I need a Z.ai account?+

No, only an API key from us.
