FLUX.1 Kontext Max

FLUX.1 Kontext Max is Black Forest Labs's experimental maximum-fidelity editing tier. It prioritizes typography accuracy, precise prompt adherence, and edit consistency for tasks where exact instruction fidelity is the primary requirement.

Image Gen

import { experimental_generateImage as generateImage } from 'ai';


const result = await generateImage({
  model: 'bfl/flux-kontext-max',
  prompt: 'A red balloon on a wooden table.'

Frequently Asked Questions

  • What does Kontext Max improve over Kontext Pro?

    Black Forest Labs positions Kontext Max above Kontext Pro for prompt adherence and on-image text, at the same inference speed. Use Max when an edit instruction or on-image text must match the prompt more literally than Kontext Pro delivers.

  • Why is typography quality a differentiator for Kontext Max?

    Rendering legible, accurate text within images is difficult for many generative models. Kontext Max targets on-image text edits: it can change text in a sign, label, or UI element while preserving surrounding context. It scores higher on those tasks than Kontext Pro.

  • Is Kontext Max suitable for multi-turn editing sessions?

    Yes. Kontext Max shares the multi-turn iterative editing capability of the Kontext suite. Each output can serve as the reference image for the next editing step. That keeps character and style aligned across many sequential changes.

  • When should I choose Kontext Max over Kontext Pro?

    Choose Max when the exact language of the edit instruction must be followed with maximum fidelity, or when text within images must be rendered accurately. Choose Pro when speed and iteration throughput are the primary concerns and moderate prompt adherence is sufficient.

  • Does the experimental designation affect reliability?

    Black Forest Labs labels Kontext Max as experimental, meaning it's still being refined. The model is fully accessible through AI Gateway. Evaluate it on your specific editing tasks to confirm it meets your quality and consistency requirements before committing to a production integration.

  • What inference speed does Kontext Max achieve?

    Kontext models achieve fast inference speeds relative to many competing models, and Kontext Max's improvements come "without compromise on speed."

  • What does FLUX.1 Kontext Max cost per image?

    Current pricing is shown on this page. AI Gateway routes across providers, and rates may vary by provider.
