New tools for building agents with the API

We’re evolving the API platform to make it faster and easier for developers to build agents. Kevin Weil, Nikunj Handa, Steve Coffey, and Ilan Bigio introduce and demo these new tools.

You know all of these people are upper middle class in San Francisco because the demos constantly revolve around traveling somewhere, booking a restaurant reservation, or buying something.

Interesting ... I'll wait for the open-source version, shouldn't take longer than 2-3 days.

can you have Ilan Bigio do more api tutorials from beginner to agents this guy is perfect for it more more lol. great job you guys!!

[Ifesol]

you gotta love competition. Not only does it lead to constant development but in return provides more satisafacttion for the end user

[AradAshrafi]

Great tools, and great flow, made possible by this wonderful group of talented and warm individuals

Thanks OpenAI. This is gonna be a game changer :)

[GRmindfreak]

I honestly hope that open AI will continue being innovative and strong despite the chaos in America. Thank you open AI for all the great tools you have offered us so far.

This is a huge update! The Responses API and Agents SDK seem like game changers for building agentic applications. A few key takeaways:

1. Responses API:

Replaces the need to stitch together multiple APIs manually.

Supports multi-turn interactions and multiple tool calls in one request.

Includes built-in tools: Web Search, File Search, and Computer Use.



2. Agents SDK (formerly Swarm):

Helps orchestrate multiple agents with handoffs.

Auto-generates JSON schemas for function calling from Python functions.

Built-in tracing and monitoring tools for debugging.

Open-source and soon available for JavaScript.



3. Assistance API Sunset in 2026:

Developers will have time to migrate to Responses API.

Responses API is a superset of chat completions and assistants.




This is a big move toward practical AI agents that actually perform tasks rather than just answering questions

This is a game-changer! I'm excited for the new consumer products this release will enable. We're about to see incredible tools that were once thought impossible for computers. Despite having state-of-the-art foundational AI models, agentic experiences were limited simply because developers lacked the right tools—until now!

Dinesh has a happy energy he’s good bring him back

The Material is Great !! Great News.
ALSO wish to congratulate the Audio. Please do all the rest of your audio this well. It's wonderful to be able to hear and follow the speakers clearly. (Mentioning because I know there was a lot of other feedback earlier on audio and you've turned it around)

I’m exhausted by the rate of change. I just want to go to sleep for a couple years until this slows down, but I know that in 2 years it’ll be so different I worry I won’t be able to catch up.

We just started a whole agentic thing at work and now we’re going to have to start over.

[srinivasukakaraparti]

Exciting info. I will try out the open source sdk as soon as it is available. Awesome

What is this AGI_final_final.docx document? 16:12

[arthur-colle]

Awesome release! assistants was close but a little but much more most devs.. Single call for multi turn function calling is exactly what most people cooked up over the last 6 months

[rasmusfoy]

Super helpful!
looking forward to the unified endpoint that incorporates the assistant api as well.

They did not complete the purchase using Computer Use tool because an unexpected dialogue popped up 10:06, and computer use did not handle it, so they guy suddenly shifted to the next topic in the demo

[lorenzlolo]

That is great - it solves sooo many problems in my applications; love it! THANKS TO OPEN AI! :)

[ProdigyStudiosLLC]

Nice, I have a feeling the API bill will be high in some cases but I hope it won't

[GiovanneAfonso]

Today feels like christmas, thank you OpenAI!!
