Model capabilities

Updated

Every model in the catalog lists its capabilities, status, input limits and prices. Check that a model has the capability you need before calling it, or the request will be refused.

Capabilities and endpoints

Capability Meaning Endpoints
Text (chat) Chat and text generation /v1/chat/completions, /v1/responses, /anthropic/v1/messages, /v1beta/models/{model}:generateContent
Vision Understanding images in a chat Same as text, with images in the messages
Embedding Text embeddings /v1/embeddings, /v1beta/models/{model}:embedContent
Image Image generation and editing /v1/images/generations, /v1/images/edits
Audio Speech transcription /v1/audio/transcriptions
Speech Text to speech /v1/audio/speech
Video Asynchronous video generation /v1/modelhub/video/tasks, then poll the task endpoint

Embedding, image and audio endpoints check the model's capability first and return model.unavailable if it is missing. Image endpoints wait up to 120 seconds, then return 202 with a polling URL; video always runs as an asynchronous task.

Model status

Status Callable Notes
Available Yes Normal service
Degraded Yes May be slower or fail more often; see service status
Retiring Yes Stops on the retirement date, so migrate early
Maintenance No Returns model.unavailable
Retired No Returns model.unavailable and will not come back

When a model starts retiring, an announcement is published and users who called it in the last 30 days are emailed.

No silent replacement

The model ID you request is the model that runs. If it is unavailable the request fails with an error instead of being switched to another model, so you decide whether to fall back.

Input limits and parameters

The input limits (such as context length and maximum output) and parameter notes on a model page are curated for choosing a model. The model itself sets the real limits, and requests beyond them may be rejected by the model.

FAQ

How long can I use a retiring model?
Until the retirement date on its model page. After that calls return model.unavailable, so migrate before then.
Will a model in maintenance be swapped for another?
No. The platform never silently replaces the model you request; calls during maintenance return model.unavailable.
How do I know whether a model accepts images?
Check the capability tags in the catalog. Only models tagged Vision understand images in a chat.
