Stability AI
Developer of Stable Audio and managed Stable Image services. Downloadable Stable Diffusion, Stable LM, Stable Code, audio and 3D releases are separated from this closed-weight subset.
Four Stable Audio generations and sixteen named managed image services reviewed, with current direct API rates and two Bedrock access records. SD3 Large/Turbo history, SD3.5 Flash classification, legacy alpha services, complete cloud hosting and private custom releases remain unresolved.
Start with the job your model needs to do. Then narrow by capabilities, provider and price.
Compare every model with the same request.
Estimate = (input tokens × input price + output tokens × output price) / 1,000,000. Include conversation history in input and billed reasoning in output. Input-only decision models ignore the output setting; enter all billed input for one decision, including its question and criteria. Media, tools and discounts are separate.
