Happy to announce that I’ve won runner’s up for the Vesuvius Challenge — an incredible initiative to read ancient Roman scrolls using AI. Taking home $50,000 as the only solo team! Read more about it below:
Ten months ago, we launched the Vesuvius Challenge to solve the ancient problem of the Herculaneum Papyri, a library of scrolls that were flash-fried by the eruption of Mount Vesuvius in 79 AD. Today we are overjoyed to announce that our crazy project has succeeded. After 2000 years, we can finally read the scrolls: This image was produced by @Youssef_M_Nader, @LukeFarritor, and @JuliSchillij, who have now won the Vesuvius Challenge Grand Prize of $700,000. Congratulations!! These fifteen columns come from the very end of the first scroll we have been able to read and contain new text from the ancient world that has never been seen before. The author – probably Epicurean philosopher Philodemus – writes here about music, food, and how to enjoy life's pleasures. In the closing section, he throws shade at unnamed ideological adversaries – perhaps the stoics? – who "have nothing to say about pleasure, either in general or in particular." This year, the Vesuvius Challenge continues. The text that we revealed so far represents just 5% of one scroll. In 2024, our goal is to from reading a few passages of text to entire scrolls, and we're announcing a new $100,000 grand prize for the first team that is able to read at least 90% of all four scrolls that we have scanned. The scrolls stored in Naples that remain to be read represent more than 16 megabytes of ancient text. But the villa where the scrolls were found was only partially excavated, and scholars tell us that there may be thousands more scrolls underground. Our hope is that the success of the Vesuvius Challenge catalyzes the excavation of the villa, that the main library is discovered, and that whatever we find there rewrites history and inspires all of us. It's been a great joy to work on this strange and amazing project. Thanks to Brent Seales for laying the foundation for this work over so many years, thanks to the friends and Twitter users whose donations powered our effort, and thanks to the many contestants whose contributions have made the Vesuvius Challenge successful!

This is how Codex is building Codex
OpenAI are massive trolls. Notice in the left side of Codex in the chess demo for GPT-5.4 in Codex the mention of GPT-6? lmao.

Just demoed some of 5.4’s computer use and frontend capabilities - check it out here! What I really like is that computer use was on an Electron app, so Codex can also make and test desktop apps as well Also yes I need a haircut :)
GPT-5.4 is here. Native computer-use capabilities. Up to 1M tokens of context in Codex and the API. Best-in-class agentic coding for complex tasks. Scalable tool search across larger ecosystems. More efficient reasoning for long, tool-heavy workflows. openai.com/index/introducing…

My slice of Codex research is making our models better at web development The best part of the job is definitely seeing what people build!
GPT-5.3 Codex is actually pretty insane with Three.js This Minecraft clone works smoothly and it didn't take too long to make I also tried Opus 4.6, but for some reason it got stuck

Second best part of the job is “inspecting outputs” and most definitely not gaming

Finished my telescope over christmas, got the first photos today! the space nerd in me is very very happy insane to think photons from space can travel for millions of years and we can just... catch them and save them as a png now to train a model to find new supernova remnants

I needed a visualizer to overlay supernova remnants on astronomy data to see if there’s enough signal to train on Codex cooked streams data, renders it as a google earth sphere, swaps in higher-res imgs as you zoom bullish on AI accelerating way more research science next year

GPT-5-Codex one shot tetris - except you play from the pov of the block (we're calling this game "you are the tetris" haha)

truly my favorite thing the team has cooked up, and definitely one of the most fun models I've had the pleasure to train!

From my brother's account. We'll miss you GPT 4.5 😢

We Marie-Kondoed the model picker! Very excited to have worked on GPT-5 but secretly even more excited to not get any more questions about “which model should I use?” Give it a try :)

GPT-5 is here. Rolling out to everyone starting today. openai.com/gpt-5/

Hanson is cracked, Codex 2 will be based on Hanson

Excited to finally share Codex with the world!! Has been an insane marathon working on this with the most cracked team ever. For example, I just merged this fix Codex wrote live on stream: github.com/openai/codex/pull…

Codex is out! I worked on making outputs verifiable — Codex cites files & terminals directly. As we trust agents with more tasks, transparency is key. We think this is a step in the right direction. Hope you enjoy it as much as it was building it :) openai.com/index/introducing…

Favorite tidbits of Singaporean architecture (And don’t worry Singapore was mostly not fun and games, I’ve been cooking something we hope you will like!)

It’s hard enough being an immigrant. This does not have to happen to one of the kindest, most genuine people at OpenAI

Hello tweeter. I’ll be in Vancouver for an indeterminate amount of time! I have no friends there so would be excited about meeting new people :) Hopefully will return home sometime this year but if not shall make the best of it.
