Field	Type	What it is
`id`	string	`gen_` and 24 letters and digits.
`object`	string	Always `generation`.
`status`	string	`queued`, `running`, `succeeded` or `failed`. See Statuses.
`model`	string	The model id.
`variant`	string	The priced option used, for example `720p` or `720p+audio`.
`units`	number	How many units the price counts (seconds, images, characters ...).
`price_usd`	number	The price: reserved while it runs, charged only on success. A failed generation is charged nothing, and `price_usd` still shows what it would have cost.
`outputs`	array	`{ url, mime }` for each file. Empty until `succeeded`. Download them with `/content`.
`error`	object	Only when `failed`: `{ code, message, retryable }`, and `reason` for a `content_policy` block. See Why a generation failed.
`created_at`	string	ISO 8601 time.
`finished_at`	string	ISO 8601 time, once final.
`outputs_kept_until`	string	Only when `succeeded`: we keep the files until then, 30 days after the generation finished. Every read gives fresh links.
`status_url`, `result_url`	string	Only on the submit answer: where to poll.
