# Generate Text to Image Job API

Generate images from text prompts with Flux.1-Schnell or SDXL-Turbo. Poll task status for progress, errors, and the finished output URL.

## About

## What it does
GPU Image Generation creates images from text prompts and returns a task you can poll for progress. Use it when you need fast, model-backed image generation without managing your own inference stack.

Send a `prompt` and, optionally, `seed`, `steps`, `width`, and `height` to the Flux.1-Schnell endpoint or the SDXL-Turbo endpoint. The Turbo variant also accepts `negative_prompt` so you can steer the output away from unwanted elements. Both generation endpoints respond with `status`, `message`, and `task_id`, which you use with `GET /tasks/:task_id` to check progress.

Polling `/tasks/:task_id` returns the current `status`, a human-readable `message`, the `task_id`, and, when the task is complete, an `output_url` for the generated file. If the task fails, the same status response includes `error`.

This service fits product features like prompt-based asset creation, concept mockups, social content generation, or internal design tooling where developers need an image job API with asynchronous results and reproducible seeds.
