@_arohan_ building agi that benefits all of humanity!

@tbpn wenda is french lmao

1/n I’m thrilled to share that our @OpenAI reasoning system scored high enough to achieve gold 🥇🥇 in one of the world’s top programming competitions - the 2025 International Olympiad in Informatics (IOI) - placing first among AI participants! 👨‍💻👨‍💻

@littmath my opinions here are very weak. i don’t know enough

[hunter @hunterlightman]

i agree! my take:
the first 90% of intelligence and reliability you can notice immediately in the chat app

the last 1% you will only notice in gdp growth

it is a very good model. it listens much better to what i want. i'm really proud of my coworkers who shipped it

[ben hylak @benhylak]

first of all, gpt-5 in ChatGPT != gpt-5 in API

but it gets more complicated. gpt-5 with minimal reasoning effort also behaves like a completely different model.

gpt-5 *is* a fantastic model with the right harness. and i believe we will see it fundamentally change products.

[hunter @hunterlightman]

@littmath i don’t think this is surprising
1. population growth would drive gdp growth even if only the 99.9th percentile people contributed
2. ai will drive massive growth if it can push out the quality of the highest skilled knowledge workers

[hunter @hunterlightman]

@littmath i think no

i think the initial chatgpt launch had economic impact that we can’t measure well. i think gpt-5 will have similar positive impact

i think you need a lot of 9s to get the growth i want to see

Dear OpenAI friends:

I'm sorry to be the one to tell you but I can say confidently now, as an ex-insider/current outsider, that the vagueposting is indeed off-putting to (most) outsiders. I *promise* you can enjoy launches without it -- you've done it before + can do it again.

@0xluffy @bryancsk @justinsunyt me too!!

@alexwei_ @MillionInt @tszzl alex go to sleep

[hunter @hunterlightman]

@HarriLEdwards @alexwei_ @SherylHsu02 @polynoamial truly! and of course we can’t have done it without standing on the shoulders of the giants before us harri :)

[hunter @hunterlightman]

huge congrats to @alexwei_, @SherylHsu02, and @polynoamial for an incredible achievement and the close of a big chapter!! onto p6 and other even harder problems 😎

alex: you’re the boss, man

[Alexander Wei @alexwei_]

1/N I’m excited to share that our latest @OpenAI experimental reasoning LLM has achieved a longstanding grand challenge in AI: gold medal-level performance on the world’s most prestigious math competition—the International Math Olympiad (IMO).

[hunter @hunterlightman]

@ryancohen25 this is so cool!!!

[hunter @hunterlightman]

@alth0u its good to publish negative results

[Noam Brown @polynoamial]

It's deeply concerning that one of the best AI researchers I've worked with, @kaicathyc, was denied a U.S. green card today. A Canadian who's lived and contributed here for 12 years now has to leave. We’re risking America’s AI leadership when we turn away talent like this.

@rapha_gl u mad bro?

[hunter @hunterlightman]

@andersonbcdefg been there :(
