Section 1
A family with one brand, three tiers
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.
Compare the options
| 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 |
Section 2
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.
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.
