Reviewer scorecard
“The most mature AI API with the largest ecosystem. Function calling, JSON mode, and assistants API cover every use case.”
“Build admin panels in hours instead of weeks. SQL queries, API connections, and components just work together.”
“Reliability has improved significantly. The ecosystem and tooling around OpenAI's API remain unmatched.”
“For internal tools that don't need to be beautiful, Retool eliminates weeks of dev time. Genuinely useful.”
“OpenAI set the standard for AI APIs. The Assistants API and real-time API point toward increasingly capable agent platforms.”
“AI-generated internal tools will commoditize this space, but Retool's head start and enterprise adoption provide a moat.”
