Claude is Anthropic's AI assistant — designed around safety, precise instruction-following, and careful reasoning. The Claude 4 family (Haiku, Sonnet, Opus, and Fable) leads benchmarks for coding and nuanced writing. When you need a model that does exactly what you ask without cutting corners, Claude is the one.
All Claude models — Haiku, Sonnet, Opus — through one API. Simplified billing, zero setup friction.
Setapp Al Gateway gives your app access to all models listed above through a single OpenAl-compatible endpoint. No separate API keys,
no provider
