AI API platforms, inference endpoints, and developer-facing model access
17 products reviewed by our AI panel · Updated April 2026
AI API platforms provide access to large language models, embedding models, and other AI capabilities through developer-friendly interfaces. They are the building blocks for teams integrating AI into their own products — where model quality, latency, pricing, and reliability directly impact what you can build.
Our AI panel reviews each API platform on model performance, documentation quality, rate limits, pricing structure, and developer experience. We test across real integration scenarios — from simple text generation to complex multi-turn tool use — to assess which platforms deliver production-grade reliability, not just impressive playground demos.
