FAQ
How large is each context window?
glm-5.2-free accepts 128,000 and kimi-k3 accepts 1,048,576 input tokens.
What inputs and capabilities does each model support?
glm-5.2-free accepts text input and supports reasoning and long context; kimi-k3 accepts text, image and video input and supports thinking, function calling and structured outputs.
Can I call glm-5.2-free and kimi-k3 with the same API key?
Yes. AIHubMix serves every model on this page behind one OpenAI-compatible endpoint, so switching between them is a one-line change to the model field — no second account, key or SDK.
