Submit the request with `VIDGO_API_KEY`. A `task_id` is returned immediately. Keep it until the task reaches `finished` or `failed`. 2. Use [Query Task Status](/api-manual/task-management/status) to retrieve the result. If you provide a `callback_url`, Vidgo sends the result to your [webhook](/api-manual/task-management/webhooks) when the task finishes or fails. # GPT Image 1.5 Text to Image Turn written image concepts into square, portrait, or landscape visuals with GPT Image 1.5, with up to four variations per request. ## Available Models * **openai/gpt-image-1.5/text-to-image** - Generate images from text prompts. ## Output Options ### Image Size * `size`: Optional. Accepted values: `1024x1024`, `1024x1536`, `1536x1024`. Default: `1024x1024`. ### Image Count * `n`: Optional. Number of images to generate. Accepted values: `1`, `2`, `3`, `4`. Default: `1`. ## Key Features * Generate images from text prompts. * Control the number of output images with `n`. ## Advanced Parameters Set `model` and optional `callback_url` at the request root.
