Flux Schnell is the free, Apache-licensed speedster — 1-4 steps, runs on consumer GPUs, image in under two seconds. Flux Pro is the paid API flagship that tops quality benchmarks. Flux Dev sits in the middle (non-commercial license) for research and fine-tuning.

Tier	Schnell	Dev	Pro
License	Apache 2.0 (commercial OK)	Non-commercial	API only
Steps	1-4	20-50	20-50
Quality	Good	Great	Best
Speed	Fastest	Medium	Medium
Use case	Realtime, embedded	Fine-tuning, research	Production art

Decision tree

Need it free and commercial: Schnell.
Doing a custom LoRA or style fine-tune for personal work: Dev.
Shipping art to paying customers where quality matters: Pro.
Building a realtime UI (typing-to-image live): Schnell.

Text-in-image reality check

Flux Pro handles short text in images well — logos, single words, brand marks. Longer sentences still break. Use Ideogram or GPT Image 2 when text is the whole point of the image.

curl https://api.bfl.ai/v1/flux-pro-1.1 \ -H "x-key: $BFL_KEY" \ -d '{"prompt":"A minimalist poster of a mountain at dawn, risograph print style"}'Black Forest Labs' hosted API is the official Pro path.

A production recipe

Use Schnell to generate rough drafts during prompt iteration — fast feedback. Once the prompt is dialed in, run the final at Pro for the client deliverable. You pay for one Pro generation instead of twenty.
