Help & Status

Fast answers when GLM or Z.ai is not doing what you expect. Start here if the chat app will not load, your API key is rejected, requests fail with 400, 401 or 429 errors, streaming stops halfway, or your Coding Plan tool reports an insufficient balance. The troubleshooting guide walks through a thirty-second status check and twelve proven fixes, from base URL mix-ups and model codes to thinking settings, content filters and rate limits. You will also find the complete list of real, official Z.ai links for the website, chat app, API console, documentation, GitHub and Hugging Face, so you can avoid look-alike sites and log in to the right place. If you just need an answer from a GLM model right now, the free GLM Chat on our homepage keeps working with no account, and the free GLM-4.7-Flash model is always available there as a fallback.
