- another realtime api trick i stumbled upon 💡 to prevent the model from "jumping in" to speak whenever you pause, you can give it a stay_silent() function that does nothing it'll call it when it knows you haven't finished your thought, even if you pause - full prompt below👇 -
00:00 - along with the gpt-oss launch 🎉 we shared some quality resources i'm surprised aren't getting more attention: - playground: gpt-oss [dot] com (!) - harmony: how we tokenize chat, CoT, tool calls - raw CoT - fine-tuning - ollama ...and so many cookbooks. links to all below 👇
- we're kicking off this year's @openai build hours! our first one – agentic tool calling, where i'll go over - CoT tool calling with o3 & o4-mini - long-horizon tasks - evaluating agentic tasks build hours are code-focused and practical, highly recommend. tune in on thursday!
- sharing our latest @OpenAI quickstart: realtime api + twilio 📞! build your own phone ai in 3min and start playing with voices, custom instructions, and functions (this is my favorite quickstart so far) happy calling! repo link 👇
00:00 - OpenAI is nothing without its people
- swarm -> agents sdk is my proud parent moment @_rohanmehta @stevenheidel did an awesome job making it production ready and adding tons of new features - tracing - guardrails - lifecycle events - provider agnostic go play, build, and deploy woth it! pip install openai-agents

- sharing a peek of the 4o demo we did at @openai’s New York tech week reception! met so many cool ny founders and builders – huge props to the team for making this happen!
00:00 - turns out you can use <xml/> tags with the realtime api to control tone with _super_ high granularity 🤷🏽♂️ @openai devday someone asked if our models could read a script with tone directions - e.g. laugh here, cough there, etc i shrugged and opened the playground... - prompt 👇 -
00:00 - small quality-of-life addition to our docs – easily copy any page to give your AI tools context on our latest features! (and no, this is not part of The 12)
00:00 - we're (finally) hosting an @OpenAI dev meetup in nyc! will have live demos, drinks, and cool builders & devs. sept 3 - space is limited, so apply below!
