How GLM-5.2 pricing works
GLM-5.2 is billed per token: a lower input price of $0.950 per million tokens for everything you send, and a higher output price of $3.00 per million for everything the model generates. To turn that into a real GLM-5.2 bill, multiply by your monthly request volume and average prompt/response length — the calculator above does exactly that.
GLM-5.2 does not list a separate cached-input rate, so every input token bills at $0.950 per million. If repeated context is a big part of your prompts, a model with prompt caching may end up cheaper in practice.
List prices move fast — always confirm the current numbers on the official Zhipu AI (GLM) pricing page before relying on them for budgeting.
