Stable Image Ultra, SD3 Large and Stable Image Core on Amazon Bedrock

Stability AI has released new image generation models, with a new high end model called Stable Image Ultra.

Three of Stability AI’s most advanced text-to-image models – Stable Image Ultra, Stable Diffusion 3 Large and Stable Image Core – are now live in Amazon Bedrock, providing high-speed, scalable, AI-powered visual content creation.

Stable Image Ultra is presented as ideal for “Ultra-realistic imagery for luxury brands and high-end campaigns”. With that description I expected it to be even more expensive than it is. Here is the on-demand per-image cost from their pricing page (US$):

This may be Stability AI backing away from open source releases, but honestly that seemed like it had to happen at some point. We’re in a bubble where companies are spending up to billions of dollars training models and giving them away for free. That can’t last forever.
