Operator guidance
Route here when budget and throughput matter more than peak fidelity; step up to SD 3.5 Large (or FLUX.1 [dev]/[pro]) for higher quality.
Use cases
- Cost-sensitive, higher-volume generation where Large's fidelity isn't needed
- Local / self-hosted use (open weights, smaller footprint than Large)
Provenance notice
- Open weights; free commercial use capped by annual revenue, enterprise licence required above the threshold
- Training set filtered to reduce unsafe content
Limitations
- Lower fidelity and detail than SD 3.5 Large
- No separately published GenEval/T2I-CompBench scores tracked yet
