A starting point.

Explore an alternative text-to-image composition with Kontext Max. For a comparison with Kontext Pro, reuse the same brief and frame rather than changing both the model and the scene.

Before you publish.

Compare requested objects, spacing and text at the same displayed size. Keep the actual quotes and results; a model name is not evidence that it wins your specific task.

Review the quote before running. A failed generation releases its reserved credits. Download the results you want to keep; stored media is retained for 30 days.

Inputs and settings

Send prompt and choose aspect_ratio. This endpoint creates a new image; it does not accept a source photograph.

Keep num_images, enhance_prompt, guidance_scale, seed and output_format consistent when comparing variants. Request a fresh quote for this endpoint.

Open this operation in the studio

Use FLUX.1 Kontext [max] through the API.

Start with this model ID for the endpoint featured on this page:

flux-pro/kontext/max/text-to-image

Input requirements belong to this model ID. Check a different mode’s schema separately when switching modes.

Available modes

Check the current model schema for supported inputs and options. Other tasks may use different model IDs.

From quote to result.

Request a credit quote for your input and settings before submitting a generation. A sample output or the price of another model is not a quote for your request.

Follow the generation workflow, then poll the job for its status and result. The API and studio use the same balance.
