FLUX.1 Kontext API Limits, Inputs and Production Checks on APIMART

The public APIMART description states: Edit images with context or generate from text using FLUX.1 Kontext Pro and Max on APIMart. Use up to 4 reference images, 9 aspect ratios, and a unified asynchronous API.

Source-backed production checks

• What is FLUX.1 Kontext? FLUX.1 Kontext is Black Forest Labs' context-aware image model family. It is designed primarily for image editing from text instructions and can also generate images from text alone.
• What is the difference between Pro and Max? flux-kontext-pro is the faster, lower-cost option at the standard price of $0.04 per image and measured at about 6 seconds for one request. flux-kontext-max targets higher output quality at $0.08 per image and measured at about 9 seconds.
• How is Kontext priced? Each variant has a fixed standard price per generated image, independent of aspect ratio and reference-image count: $0.04 for Pro and $0.08 for Max. Your account's multiplier or discount may change the actual charge; check the task result for the recorded cost.

Validate every request field against the linked API reference. Persist task identifiers for asynchronous routes, use bounded polling and backoff, and do not count submission as completed output.

FAQ

What public evidence was checked for FLUX.1 Kontext?

The live APIMART model page and its linked API reference were checked on September 2, 2026.

Where are accepted inputs and options defined?

Use the linked API reference as the source of truth for request fields, enumerations and incompatible combinations.

How should asynchronous work be measured?

Persist the returned task identifier and count success only after the final task status reports a completed output.

Which failures need separate handling?

Treat validation, authentication, balance, rate-limit and server failures as distinct operational states.

Can public constraints change?

Yes. Recheck the live model page and API reference before shipping or changing a production preset.
