Technical profile

What developers should know

01

Max within the FLUX.2 family

Black Forest Labs positions Max for maximum quality, editing consistency, prompt following, style representation, and world knowledge. The family overview distinguishes it from Pro for production scale, Flex for adjustable control, and Klein for high-volume or local use.[1]

02

References and grounding

The API comparison documents up to eight reference images for Max, while the browser playground supports up to ten. Max can invoke grounding search when prompted; workflows should record whether that changing external context was used.[1]

03

Asynchronous delivery

BFL’s generation API returns a request ID and polling URL. The resulting signed image URL is temporary, so production workflows should retrieve the asset promptly and store it under their own retention and access policy.[2]

Choose the artifact

Official checkpoints

Use the exact documented model or endpoint identifier and record input assets, parameters, output metadata, and failure states for reproducible media workflows.[1] [2]

Deployment note

Persist the polling URL returned by the submit response, fetch the signed result before it expires, and separate grounded generations from fixed-reference evaluations because live search can change the output context.[2] [1]
