🇨🇳 Z AI (Zhipu AI) 免费 LLM API

📌 备注：Registration accepts overseas phone numbers ([registration FAQ](https://docs.bigmodel.cn/cn/faq/registration-login.md)) and the chat API does not require real-name verification: 目前调用 API 并不强制要求实名认证 ([authentication FAQ](https://docs.bigmodel.cn/cn/faq/authentication-issues.md)). The Batch API does require it ([batch FAQ](https://docs.bigmodel.cn/cn/faq/batch-api-issues.md)). The same free models are served from the international platform at `https://api.z.ai/api/paas/v4` ([endpoint](https://docs.z.ai/guides/develop/http/introduction)), where GLM-4.7-Flash, GLM-4.5-Flash and GLM-4.6V-Flash are all priced Free ([pricing](https://docs.z.ai/guides/overview/pricing.md)). Z AI has announced that GLM-4.5-Flash will be retired and its requests auto-routed to GLM-4.7-Flash ([model page](https://docs.bigmodel.cn/cn/guide/models/free/glm-4.5-flash.md)); the announced date has already passed while the model is still catalogued and still priced Free, so treat that row as living on borrowed time.

额度与限速可能随时调整，请以 Z AI (Zhipu AI) 官网 为准。
