Capability profile

Operator guidance

The modern open-weight workhorse: route here when you want current quality with open weights and a permissive (sub-$1M revenue) licence. Use the Turbo variant for speed/cost; step to FLUX [pro] or Imagen for the top closed-model fidelity.

Use cases

• Open-weight deployments wanting a current, strong model
• Commercial use under the Community Licence (free under $1M revenue)
• Fine-tuning / customisation on a modern flow-matching base

Limitations

• Community Licence has a revenue threshold for free commercial use
• Native resolution ~1MP; needs upscaling for large assets
• No SD3.5-Large-specific GenEval score cited here. For family context, the SD3 paper reported GenEval up to ~0.74 for the (predecessor) SD3 — not a SD3.5 Large number. An independent Elo does now exist: Artificial Analysis Text to Image Arena (artificialanalysis.ai/image/leaderboard/text-to-image, confirmed 2026-08-19, SCO-462 sweep) ranks 'Stable Diffusion 3.5 Large' #115 of ~147 models tracked, Elo 1034 — essentially tied with the Large Turbo variant on this arena. A different benchmark type than GenEval/T2I-CompBench, not a substitute for one
