setting "prompt_cache_retention" to "24h" in the Responses API can lead to significant cost and latency improvements in gpt-5.1, since prompts will be cached much longer than the normal 5-10 minutes

I’m hiring for the API Frontiers team at OpenAI! We take the latest breakthroughs from research and turn them into developer products - designing APIs that feel natural, powerful, and scale to billions of users.
gpt-5.1 is now available in ChatGPT! smarter, faster, and with more options to customize its personality - because sometimes you don't need to be told that every question is a great question
exciting to see my current and former employers working together to scale AI compute!

another successful DevDay in the books. thanks to everyone who attended and also to our incredible events team - it was our biggest one yet!
between the Apps SDK, Codex SDK, and AgentKit - how many startups did OpenAI just create today?

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
