At Stanford this weekend, we built Nexus: a graph visualization software that helps you discover meaningful relationships at events
We scraped Slack data to extract interests and backgrounds, then using NLP to find similarities!

lol didn’t expect this many people to see this: these fields aren’t dying, just showing how startups that generalize will fail. huge believer in companies using openai architecture to provide NICHE use cases; a lot of companies just got created from this announcement

a few life updates:
- turned 19 today!
- interning
@hitachi
, train automation & signalling for nyc railroads
- working on end-to-end visual reasoning for humanoids
- will be open sourcing a lot of ML/AI experiments in the next few months
dm me! would love to connect :)

I use voice to voice every day when I’m walking the dog, driving or building new projects. It’s like having a podcast that you can talk to about literally anything — I highly recommend it over traditional podcasts or music when you are free
Very excited for Monday
We’ll be streaming live on at 10AM PT Monday, May 13 to demo some ChatGPT and GPT-4 updates.

gpt-4 has taken over twitter. take a breather & learn some new math:
4k lines of ML & 2 new algorithms later, I've identified a novel Fourier interpretation of seismic decay with 3D frequencies — with incredible potential to design affordable earthquake-resistant structures.

maybe the challenge isn’t about compression but the friends we make along the way
I have an update for those trying out Neuralink's compression challenge. I put some effort into calculating the legit theoretical max compression possible and.... tada it's 3.439

We ran 500 agents in parallel using census data to represent and model their interactions. We used chain of thought reasoning to model their movement
We use these patterns to optimize Los Angeles transit to maximize mobility at the lowest possible carbon cost using our own PPO!

One Sohu server runs over 500,000 Llama 70B tokens per second, 20x more than an H100 server (23,000 tokens/sec), and 10x more than a B200 server (~45,000 tokens/sec).
