🚀 **GLM-5.2 is live · currently #1 open source, callable in the OpenAI-native format**

Zhipu Z.ai's `glm-5.2` launched on June 16 — fully MIT open weights with a 1M context window, topping multiple long-horizon coding leaderboards as the #1 open-source model. APIYI added it the day before yesterday (June 18); it has good word-of-mouth and you can call, test, and use it directly now.

Calling and pricing (FYI):

* Pricing: single top-ups over \$100 get 9% off and up, with lower rates for large accounts.
* Format: only the OpenAI-native format is supported for now.
* ClaudeCode: not yet supported (it needs Anthropic's native protocol endpoint); we'll announce promptly via `/live` once it is.

Try it out and send feedback — we keep operations running.
