Reviewer scorecard
“Mature API, excellent SDKs, and the content model is flexible. The enterprise choice for headless CMS.”
“The most mature AI API with the largest ecosystem. Function calling, JSON mode, and assistants API cover every use case.”
“Expensive for what it is. Sanity and Payload offer better DX at lower cost. Only justified for enterprise compliance needs.”
“Reliability has improved significantly. The ecosystem and tooling around OpenAI's API remain unmatched.”
“The editor experience is functional but uninspiring. Sanity's customizable studio is more pleasant to work in.”
“OpenAI set the standard for AI APIs. The Assistants API and real-time API point toward increasingly capable agent platforms.”
