## Start a generation

`client.generations.create(GenerationCreateParamsbody, RequestOptionsoptions?): GenerationCreateResponse`

**post** `/generate`

Starts a model generation using type, prompt, workspace_id, project_id, optional model endpoint ID, and optional model parameters. Use type=image|video|audio|text and model IDs returned by GET /models or list_models. Poll the returned run_id via GET /runs/{runId} for progress and outputs. Mutating public API requests support an optional Idempotency-Key header for client retries; duplicate keys within two hours return idempotency_duplicate.

### Parameters

- `body: GenerationCreateParams`

  - `project_id: string`

    Project identifier. Use the public API ID returned by list projects; it must start with prj_.

  - `prompt: string`

    Generation prompt

  - `type: "image" | "video" | "audio" | "text"`

    Generation type. Use "image", "video", "audio", or "text"; do not pass model families such as "t2i" or "i2v".

    - `"text"`

  - `workspace_id: string`

    Workspace identifier. Use the public API ID returned by list workspaces; it must start with ws_.

  - `model?: string`

    Model endpoint ID, not a display name. Use list_models (or GET /models) to find accessible endpoint IDs for the requested type.

  - `params?: Record<string, unknown>`

    Model parameters
