About Flux Kontext Max
Flux Kontext Max is the premium tier of BFL's Kontext line, optimized for two things Pro struggles with: rendering legible text inside images and following complex multi-clause instructions without ignoring half of them. It costs more per edit than Pro, but the quality gap is most visible when your prompt has multiple constraints (e.g., "change the background AND swap the shirt color AND keep the brand text readable on the bag").
Heads up
The price jump from Pro is steep. Use Max only when text rendering or compound instructions actually matter — for simple edits, Pro is equivalent.
