When to use FLUX.1 Kontext Pro

Updated 2026-07-31

Where this model earns its cost — and where it doesn't.

FLUX.1 Kontext Pro accepts text and image inputs to produce edited image outputs. It specializes in mask-based inpainting and targeted refinement, allowing you to modify specific regions while preserving the rest of the frame.

On Kyma, the model runs on the cheap tier with medium speed. Prompt caching applies to repeated instruction prefixes, and every request benefits from automatic failover if a serving path degrades. Response metadata includes exact costs in usage.cost and the active model in the X-Kyma-Model header.

This model does not support text generation, logical reasoning, or structured outputs. It is optimized for guided edits rather than generating images entirely from scratch, and token limits do not apply to its image-based workflow.

Masked Object Replacement

Swap specific regions of an image using a binary mask and a text prompt.

Iterative Image Refinement

Improve composition or details in an existing image through guided edits.

Targeted Detail Enhancement

Sharpen or adjust specific areas without altering the full frame.

Batch Asset Editing

Apply consistent text-guided modifications across multiple source images.

Not ideal for: Do not use this model for generating images from scratch, text generation, or tasks requiring logical reasoning or structured JSON outputs.

FAQ

Common questions about this model.

How much does FLUX.1 Kontext Pro cost?

$0.054 per image. Per image. Async generation; you only pay for successful renders.

How do I use FLUX.1 Kontext Pro?

Kyma is OpenAI-compatible: point your SDK's base URL at https://kymaapi.com/v1, use your Kyma API key, and set the model to flux-kontext-pro. Signing up is free and includes $0.50 of credit — no card required.

Does this model accept text-only prompts?

No. It requires an input image alongside a text prompt to perform edits or refinements.

How does prompt caching work with this model?

Repeated prompt prefixes are billed at 10% of the standard input rate, reducing costs for workflows with consistent instructions.

How do I verify which model processed my request?

Kyma returns the exact model identifier in the X-Kyma-Model header and reports precise costs in the usage.cost field.
