the OpenAI Responses API is now the first truly agentic API 🚀 developers can combine MCP servers, code interpreter, reasoning, web search, and RAG - all within a single API call - to build the next generation of agents 🤖
OpenAI DevDay 2025 registration is now open - see you there!
DevDay registration is open! → devday.openai.com Spots are limited, so we’ll draw attendees by lottery (rather than first-come, first-served).
new version of image generation in the API with improved preservation of input images - much better for editing!
We've improved image generation in the API. Editing with faces, logos, and fine-grained details is now much higher fidelity with features preserved. 🔍 Edit specific objects, create marketing assets with your logo, or adjust facial expressions, poses, and outfits on people.
those $100M offers might sound compelling now, but if Trump fires Powell that won’t even be enough for a cup of coffee
