How FLUX.1 [schnell] rates across core capability dimensions, with the task-level evidence behind each rating.
Designed for 1-4 step generation; sub-second to ~1s on a fast GPU.
Good for a fast model; below FLUX.1 [dev]/[pro] and top realism models.
Inherits FLUX-class adherence, slightly reduced by distillation.
No schnell-specific GenEval score is published. As a proxy, FLUX.1 [dev] — which schnell is timestep-distilled from — scores ~0.66 on GenEval (automated compositional alignment: object presence, counting, colours, position, attribute binding; 0–1 = fraction of checks passed), i.e. roughly 1 generation in 3 misses a requested attribute; schnell should sit at or slightly below that given the distillation tradeoff. This is NOT schnell's own measured score. Independent proxy (third-party getimg.ai comparison of FLUX.1 [dev], 2026-06); see the benchmarks block and limitations for the proxy caveat and schnell's own Arena Elo.
Better than SDXL-era models; weaker than dev/pro and DALL·E 3.
Targets roughly 0.1-2 megapixels; upscale for larger.
Benchmarks
| Benchmark | Score | Config | Source |
|---|---|---|---|
| GenEval | ≈0.66 | Schnell-specific GenEval is not published; this is the FLUX.1 [dev] figure it is distilled from (third-party comparisons report ~0.66-0.71 depending on sampling). Schnell should be expected to score at or slightly below dev. | independent ↗ |
Operator guidance
Route here when speed and cost per image dominate and top-tier fidelity isn't required. Step up to FLUX.1 [dev]/[pro] for higher fidelity, or to DALL·E 3 for the strongest prompt following and in-image text.
Use cases
- Rapid iteration and concepting where throughput beats peak fidelity
- High-volume, low-cost generation (thumbnails, option sets, feeds)
- Interactive / near-real-time UX
Provenance notice
- Open weights with no built-in content-provenance metadata (no C2PA/watermark by default)
- Base training-data composition not publicly disclosed by Black Forest Labs
Limitations
- Distillation trades away some fine detail and diversity versus FLUX.1 [dev]
- Weaker than DALL·E 3 on complex compositions and legible text
