Trust & security
Security

Review Stability AI's data handling policy. API images processed on Stability's infrastructure. Open source self-hosted deployment keeps data private.

Adobe enterprise security standards. SOC 2 Type II. ISO 27001. GDPR compliant. FedRAMP eligible. IP indemnification for commercial use.

Privacy notes

Review Stability AI's privacy policy and commercial licence terms for the specific model (open source licence varies by Stable Diffusion version). API usage subject to Stability's terms.

Adobe processes image generation prompts and inputs under Adobe's enterprise privacy terms. IP indemnification covers commercially generated images under eligible enterprise plans.

Verdict
Pros
  • $0.003/image pricing is among the most cost-efficient for high-volume commercial image generation
  • Open source Stable Diffusion 3.5 enables fully private self-hosted deployment
  • Largest community ecosystem of fine-tuned models for custom styles via Civitai and Hugging Face
  • ControlNet structure guidance provides advanced creative control not available in simpler APIs
  • IP indemnification is a decisive advantage for legal-risk-conscious enterprise and regulated industry marketing
  • Adobe Stock training data provides cleaner copyright provenance than web-scraped model competitors
  • Native Creative Cloud integration reaches the designers already using Photoshop and Illustrator
  • Firefly Image 3 quality is competitive with midrange image generation models for commercial use cases
Cons
  • Company financial and leadership instability creates product longevity uncertainty
  • Open source licence terms require review — commercial use has eligibility requirements by model version
  • API quality for photorealism below premium Midjourney and Imagen 3 for highest-quality outputs
  • Premium pricing reflects commercial safety positioning — significantly more expensive per image than Stability AI API
  • Creative quality below Midjourney v6 for artistic and stylised outputs targeting creative excellence
  • Enterprise API requires Adobe enterprise agreement — not accessible for individual developers without Creative Cloud
