Flux

Black Forest Labs' photorealistic image models, priced per image.

About

Flux is the image model family from Black Forest Labs, known for photorealistic detail, strong prompt following and accurate text rendering. The current FLUX 3 models run through the company's API and playground on a pay-per-image credit system, while a smaller Klein model is also available as open weights for self-hosting.

Key features

• Text-to-image generation with detailed, photorealistic results
• Image editing and multi-reference generation from one endpoint
• Structured scene layouts for placing elements precisely
• Resolution options from small drafts up to 4K output
• A smaller open-weights Klein model for local use
• Playground access with the same pricing as the API

Limitations to know

AI-generated images can contain errors and artefacts, so check details before publishing. There is no free tier for the flagship models, costs rise steeply with resolution, and licensing terms differ between the API models and the open-weights Klein model.
