We are starting to see some nuanced discussions of what it means to work with advanced AI In this case, GPT-5 Pro was able to do novel math, but only when guided by a math professor (though the paper also noted the speed of advance since GPT-4). The reflection is worth reading.

My annoying middle ground theory of AI adoption is that many enthusiasts dont take into account that real organizations introduce huge complexity that AI models struggle with But skeptics don’t take into account that AI may assist with its own adoption by solving some complexity

I think congrats again to OpenAI for cooking with GPT-5 Pro. This is the third time I've struggled on something complex/gnarly for an hour on and off with CC, then 5 Pro goes off for 10 minutes and comes back with code that works out of the box. I had CC read the 5 Pro version

We tested our controllers in hardware on the real LIGO system. Our results show that Deep Loop Shaping: 🔹controls noise up to 30-100 times better than existing controllers. 🔹can eliminate the most unstable, difficult feedback loop as a meaningful source of noise on LIGO for

I really hope to verify this in my house soon!!
Today we posted a short write-up on the website The same Helix model that folded towels and sorted packages can now load a dishwasher No new algorithms, no special-case engineering, just new data https://t.co/xJ4S9JXtsJ

At @OpenAI, we believe that AI can accelerate science and drug discovery. An exciting example is our work with @RetroBiosciences, where a custom model designed improved variants of the Nobel-prize winning Yamanaka proteins. Today we published a closer look at the breakthrough. ⬇️

We have data on the environmental impact per AI prompt: Gemini: 0.00024 kWh & 0.26 mL water ChatGPT: 0.0003 kWh & 0.38 mL ...the same energy as one Google search in 2008 & 6 drops of water. Seems to be improving, too: Google reports a 33x drop in energy use per prompt in a year.

Claim: gpt-5-pro can prove new interesting mathematics. Proof: I took a convex optimization paper with a clean open problem in it and asked gpt-5-pro to work on it. It proved a better bound than what is in the paper, and I checked the proof it's correct. Details below.
