frequently asked questions
Which Z.AI models are available through Impossibl?
The directory lists 11 models from Z.AI available through the Impossibl API, including GLM-4.5, GLM-4.5 Air, and GLM-4.6. Open each model page for its API identifier, capabilities, and current pricing.
How much do Z.AI models cost?
Z.AI model prices vary by model and usage. All rates below are published base API rates in USD. For token-priced models, published input rates start at $0.15 per million input tokens. Published output rates start at $0.50 per million output tokens. Input and output minima may refer to different models. Individual model pages include published cache prices and billing units. Applicable fees and workspace-specific pricing can affect the amount paid.
What context windows do Z.AI models support?
Among Z.AI models with a published limit on Impossibl, the largest context window is 1,040,000 tokens, listed for GLM-5.2 Fast. Context limits vary by model and are separate from maximum output limits.
What inputs and capabilities do Z.AI models support?
Available model types include text generation. Published input support includes image and text; support varies by model. Tool-calling support is unspecified for 11 models.
How do I use Z.AI models through an API?
Use the exact model identifier from the model page with the Impossibl API. For example, select zai/glm-4.5 with /v1/chat/completions. Endpoint compatibility depends on the selected model. The API quickstart explains how to create an API key and send a request.
