Z.ai launches GLM-5.3 API

It is priced the same as GLM-5.2.

GLM-5.3 is built for coding, defensive cybersecurity, and long-horizon agentic tasks.
It is available through the official API and partner model gateways.

Developers can now use GLM-5.3 for coding, cybersecurity, and agentic workloads without paying more than for GLM-5.2.
