## Create a generation

`$ luma-agents-cli generations create`

**post** `/generations`

Submit an image generation or edit job. Returns immediately with an opaque job ID to poll via GET /generations/{id}.

### Parameters

- `--prompt: string`

  Text prompt

- `--aspect-ratio: optional "3:1" or "2:1" or "16:9" or 6 more`

  Output aspect ratio

- `--image-ref: optional array of object { data, media_type, url }`

  Reference images for style/content guidance. Up to 9 for type 'image', up to 8 for type 'image_edit'.

- `--model: optional "uni-1" or "uni-1-max"`

  Model identifier. `uni-1` is the default tier; `uni-1-max` produces higher-quality output than `uni-1` at a higher per-image price. Both models are available to all accounts — see Pricing for per-image rates.

- `--output-format: optional "png" or "jpeg"`

  Output image format

- `--source: optional object { data, media_type, url }`

  Reference image for guided generation. Provide either url or inline base64 data (not both).

- `--style: optional "auto" or "manga"`

  Style preset (auto, manga)

- `--type: optional "image" or "image_edit"`

  The kind of generation to perform

- `--user-id: optional string`

  Your end-user's stable opaque identifier (no PII). Forwarded to upstream model providers as their per-user tagging field so trust & safety violations can be attributed to a specific end-user rather than the whole API account. Also used for per-end-user usage breakdowns in /v1/usage. Strongly recommended for partner integrations.

- `--web-search: optional boolean`

  Enable web search grounding — the agent can search the web and download reference images before generating.

### Returns

- `generation: object { id, created_at, model, 5 more }`

  Generation status and output

  - `id: string`

    Generation identifier

  - `created_at: string`

    Creation timestamp

  - `model: "uni-1" or "uni-1-max"`

    Model used

    - `"uni-1"`

    - `"uni-1-max"`

  - `state: "queued" or "processing" or "completed" or "failed"`

    Current state of the generation

    - `"queued"`

    - `"processing"`

    - `"completed"`

    - `"failed"`

  - `type: "image" or "image_edit"`

    The kind of generation to perform

    - `"image"`

    - `"image_edit"`

  - `failure_code: optional "content_moderated" or "generation_failed" or "budget_exhausted" or 6 more`

    Machine-readable failure code for programmatic handling

    - `"content_moderated"`

    - `"generation_failed"`

    - `"budget_exhausted"`

    - `"output_not_found"`

    - `"image_too_large"`

    - `"unsupported_format"`

    - `"corrupt_input"`

    - `"invalid_request"`

    - `"rate_limited"`

  - `failure_reason: optional string`

    Human-readable failure description

  - `output: optional array of GenerationOutput`

    Generated outputs (populated on completion)

    - `type: string`

      Media type (e.g. image)

    - `url: string`

      Presigned URL (1hr expiry)
