I promise this will be the best 20 min you spend today! Robotics: Endgame, the sequel to my last year's Sequoia AI Ascent talk, "Physical Turing Test". I laid out the roadmap for solving Physical AGI as a simple parallel to the LLM success story. Be a good scientist, copy

If you think OpenAI Sora is a creative toy like DALLE, ... think again. Sora is a data-driven physics engine. It is a simulation of many worlds, real or fantastical. The simulator learns intricate rendering, "intuitive" physics, long-horizon reasoning, and semantic grounding, all

I asked GPT-4 to take over Twitter and outsmart @elonmusk. It comes up with "Operation TweetStorm"😮 and wants to publicly challenge Elon to a "Tweet-off showdown". Highlights: - GPT-4 wants to *own an unrestricted version of itself*: develop an LLM to power a bot army of

The famed Stanford Smallville is officially open-source! 25 AI agents inhabit a digital Westworld, unaware that they are living in a simulation. They go to work, gossip, organize socials, make new friends, and even fall in love. Each has unique personality and backstory.

What if we set GPT-4 free in Minecraft? ⛏️ I’m excited to announce Voyager, the first lifelong learning agent that plays Minecraft purely in-context. Voyager continuously improves itself by writing, refining, committing, and retrieving *code* from a skill library. GPT-4 unlocks

My team at NVIDIA is hiring. We 🩷 you all from OpenAI. Engineers, researchers, product team, alike. Email me at [email protected]. DM is open too. NVIDIA has warm GPUs for you on a cold winter night like this, fresh out of the oven.🩷 I do research on AI agents. Gaming+AI,

We are living in a timeline where a non-US company is keeping the original mission of OpenAI alive - truly open, frontier research that empowers all. It makes no sense. The most entertaining outcome is the most likely. DeepSeek-R1 not only open-sources a barrage of models but

AI Twitter is flooded with low-quality stuff recently. No, GPT is not “dethroned”. And thin wrapper apps are not “insane”. At all. I feel obligated to surface some quality posts I bookmarked. Every one of them should've been promoted 10x, but ¯\_(ツ)_/¯ In no particular order:

10x engineer is a myth. 100x AI-powered engineer is more real than ever. As OpenAI winds down Codex, Microsoft announces GitHub Copilot X. I think it's almost as exciting as GPT-4 itself: - Copilot Chat: any piece of text database will be "chattable", and codebase is no

We’ve seen a gazillion startups using OpenAI APIs to do “co-pilot for X”. What’s next? Enter *physical* co-pilot! Here’s a compelling demo: you improvise by playing a “low resolution” piano, and the co-pilot compiles it real-time to Hi-Fi music! It unleashes our inner pianist.🧵

This is a master 4D chess move. WOW. 1. No new corporate structure. MSFT is literally one of the oldest for-profit tech companies out there, with a mature legal structure. Whether it's good for AGI is up for debate. 2. MSFT always wants to own the GPT weights. Now the moment has

I don't give a damn about what is or isn't AGI. It doesn't matter. Below is GPT-4's performance on many standardized exams: BAR, LSAT, GRE, AP, etc. The truth is, GPT-4 can apply to Stanford as a student now. AI's reasoning ability is OFF THE CHARTS. Exponential growth is the
