why we built the Responses API developers.openai.com/blog/respons...

just popped a bunch of tylenol so i can understand LLMs better

i was privileged to become american thanks to the h-1b visa. the program has its flaws, but adding a $100k "bribe" (which can be arbitrarily waived if you please the right people) is not the answer

first they came for the immigrants, then they came for the comedians - but it’s fine since i’m not any of those things

ChatGPT now fully supports MCP tools, including write actions! just turn on the new "developer mode" in the settings

for every step forward the US takes in AI, we take two steps backwards somewhere else. this week it's destroying a perfectly good satellite and canceling funding to one of the most promising technologies for beating cancer

ensuring that AGI benefits all of humanity requires accepting a simple fact: that not all of humanity will have access to the internet all of the time. that's why local, open source models are so important.

this is going to be an exciting week!

Trump's war on numbers continues: after firing the head of labor statistics he's now cut funding to one of America's greatest mathematicians

you can't trust the economic data coming out of Venezuela these days. any time President Maduro sees a report he doesn't like he'll just fire whoever wrote it

you think you're locked in? my deadbolt is broken and i literally can't open the door

new version of image generation in the API with improved preservation of input images - much better for editing!

those $100M offers might sound compelling now, but if Trump fires Powell that won’t even be enough for a cup of coffee

OpenAI developers: have you tried out Remote MCP servers in the Responses API? what can we improve?

lots of excitement for MCP in Paris this week!

the OpenAI API is back to running at 100% again, plus we dropped o3 prices by 80% and launched o3-pro - enjoy!

happy pride!

a large part of why MCP has been so successful is due to how open the Anthropic team has been to collaboration. it's been great working with them, and congrats to their team on the launch of Claude 4!

we built the MCP + Responses API integration in record time, largely thanks to Codex. i personally kicked off over 50 tasks and merged thousands of lines of Codex-written code

you're now just one API call away from connecting with hundreds, and soon thousands, of tools across the web

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 🤖

structured outputs in the API just got even more structured! platform.openai.com/docs/guides/...

google has achieved state of the art in another benchmark

the new 2.5 Flash evals are seriously impressive - congrats to the Gemini team!

what are some cool remote MCP servers you've seen? and what are you building with them?

i’ve used codex internally for a few months and have cut days or weeks off several projects on the API team. software engineering will truly never be the same openai.com/index/introd...

we just released reinforcement fine-tuning on o4-mini! 🚀
