o3-mini is now available: https://t.co/CkyJ9RCrXk

I’m using the o3-mini-high version, and it definitely feels faster than o1. The output seems similar (a promising sign given this is just the mini version)

Looking forward to the full #o3 release—I expect a much bigger leap

ChatGPT o1 vs. DeepSeek R1: Interactive Tools. I gave both AIs the same prompt. o1 repeatedly failed whereas DeepSeek took longer but worked. This isn’t an isolated example.

A good reminder to continue mapping the jagged frontier, which is moving over time.

I've been preparing examples to show my students where AI can struggle… and I came across this one.

I asked ChatGPT4o to generate an image of a glass COMPLETELY full of water. Sounds simple, right? Turns out, it’s surprisingly hard.

The new OpenAI Operator lets AI control tools we use daily. Still early and buggy, but a glimpse into a future where AI handles email, posts, and more. I tested it, and it even published a LinkedIn post for me (later taken down). Exciting yet unsettling. #AI #Operator #OpenAI

The 'Stargate' AI Initiative seems to make two things clear:

(1) OpenAI is committed to be being truly terrible at naming things
(2) The investment is massive bet on AI as the future of the American economy.

My favorite document for combining the ideas of market (in)efficiency and value investing: Alphanomics by Charles Lee and Eric So. Worthy of study.
