Models

Model	ID	Supports
Tazo Large	`tazo-large`	One `choice` or `noul` question. A `choice` has 2 to 32 options.
Tazo Small	`tazo-small`	One `choice` question with 2 to 32 options, including a `NO_TOOL` option.

tazo-large is the default when model is omitted.

Check capabilities at runtime

Call GET /v1/models to see each model’s capabilities and whether it is ready. Use this instead of hard-coding limits.

curl https://api.tazolabs.com/v1/models \
  -H "Authorization: Bearer $TAZO_API_KEY"

Capability	Meaning
`question_types`	Question types the model accepts.
`max_questions`	Most questions allowed in one request.
`max_choice_options`	Most options in a `choice` question.
`requires_no_tool_choice`	Whether the request must include a `NO_TOOL` choice.
`max_audio_seconds`	Longest audio accepted, if limited.
`required_sample_rate_hz`	Required sample rate, if any.

Legacy model names

Older internal model IDs and the previous general and specialised aliases are still accepted as input during migration. Responses and /v1/models always use tazo-large and tazo-small. If you compare the request model with the response model, switch your requests to the new names. Aliases are resolved before idempotency checks, so a retry that uses an alias or its legacy ID reuses the same job.
