That feeling when you can’t tell if your lower bound should be higher or your upper bound should be lower

@jeffreygwang I wanted to get married 4/5/2025 this year (since 45 is the square root of 2025). It would have been 🔥! Was eventually shot down by family bc it was too close to 清明节 and thus inauspicious

The GPT-5 unicorn’s hair is almost as good as @rapha_gl’s

[Sebastien Bubeck @SebastienBubeck]

Here at @OpenAI we've cracked pretraining, then reasoning, and now we're experimenting with a new set of techniques that maximally leverage their interaction. GPT-5 is just the first step in this direction, and we're incredibly excited to see where scaling this up will lead us!

Can confirm Hansen is a walking cache of Google Maps in the Bay Area.

Cool eval work! 💪

[Hansen Qian @Hansenq]

🗺️ Can LLMs navigate San Francisco purely from memory, without Google Maps?

I tested spatial reasoning of the 19 top LLMs. Honestly...they were all pretty bad.

Best in cities: o3 (38%)
Best on highways: grok-4, o3, o4-mini (62-64%)

.@Lightskis is building Cursor for Engineering Docs.

Spend less time writing— their AI Agent searches through your codebase and existing docs to build a draft. Then, continue refining in their multiplayer editor.

I'm interested in complex dynamical systems such as ant colonies, slime molds, and new jersey

2x cheaper & faster is for English, but for other languages (especially non-latin-script) expect - thanks to our new tokenizer -- even up to 9x cheaper/faster!

GPT-4o is here! Stronger multimodal and multilingual capabilities, and most importantly, free!

[OpenAI @OpenAI]

Say hello to GPT-4o, our new flagship model which can reason across audio, vision, and text in real time: https://t.co/MYHZB79UqN

Text and image input rolling out today in API and ChatGPT with voice and video in the coming weeks.

Someone asked AI to create images of Taylor Swift working at Walmart on Black Friday. This is what it came up with.

Satya is a class act

[Satya Nadella @satyanadella]

At the end of the day, the greatest privilege of my job is working with people who are driven by mission. These last 5 days, I saw people across OpenAI remaining calm and resolute in driving their mission despite all that was happening around them. And I saw people across Microsoft remain focused on our mission and serving our customers and partners, stepping up to help in every way. This is what I’m especially thankful for going into the Thanksgiving holiday. Thank you for your resolve and for the work you do each day to advance AI safely and responsibly and distribute its benefits to all of humanity.

[Elizabeth Yang @eytyang]

Back at it tomorrow 🙌🙌

We have reached an agreement in principle for Sam Altman to return to OpenAI as CEO with a new initial board of Bret Taylor (Chair), Larry Summers, and Adam D'Angelo.

We are collaborating to figure out the details. Thank you so much for your patience through this.
