Decision notes
Official-document research
Based on the cited documentation. We did not use the product, purchase a plan, or run quality, speed or reliability tests in this review.
Consider it for
- Developers able to manage model-specific deployment and rights
Choose another approach if
- Assuming every generation has a permissive open-source license
- Factual images or production results without review
Pricing and conditions
Documented terms
Download access is not the total cost. For direct commercial use/distribution of SD3.5 Large materials, bundled-license §III requires registration and separate permission above USD1 million aggregate annual revenue for you/affiliates; enterprise pricing is custom. §III does not apply when a Licensee supplies materials/derivatives as part of an integrated end user product; this is not an exemption for every API or hosted service. SDXL1.0 has different terms. Local GPU, electricity and storage cost extra. API rates, credit conversion, currency, tax, region and billing remain unconfirmed; no consumer-plan price is substituted.

Pricing or terms sourceCode, model and service licensing
SDXL1.0 uses CreativeML OpenRAIL++-M with use restrictions and downstream notices; its card's research intent is not an unconditional commercial warranty. SD3.5 Large's bundled §III registration/revenue rules concern direct commercial use/distribution. §III does not apply to recipients obtaining materials/derivatives from a Licensee as part of an integrated end user product; do not extend this to all APIs/hosting. Other applicable terms include attribution/Powered by duties and a ban on using materials/outputs to improve unrelated foundational generative models. Lawful output ownership is not third-party clearance. UI/code, fine-tunes and other generations have separate terms; hosted training/retention policies remain unconfirmed.
Basis and limits of the recorded score
The existing 4.6 score is retained without its original worksheet. No output, speed, compatibility or competing-cost test was performed and no new score was assigned.
Overview
Stable Diffusion names several model generations, not a single product with one license. SDXL1.0 documents a base model with an optional refiner and image-to-image workflow; SD3.5 Large is a separate release with its own implementation and Community License. Match the model, interface and editing components before planning a workflow.
Consider downloadable weights when you can manage compute and model permissions. The model cards identify limits in factual representation and, for SDXL, text, faces and composition. This directory did not test those limits or compare newer models. Self-hosting does not eliminate hardware costs or establish what a hosted API does with inputs.
