To deepen the public conversation about how AI models should behave, we’re sharing our Model Spec — our approach to shaping desired model behavior. openai.com/index/introduc…

Mercedes DrivePilot only works on these pre-mapped highways under 40 miles per hour. Tesla’s system can work on any road — highway or city streets. The media is reporting that Mercedes system is more advanced. It is a good example of why you should not trust the media.

The Tesla ADAS Operators are still validating Supervised FSD v12.x? on my Unprotected Left Turn. Perhaps last week's validation did not pass the test. These sightings have been fairly good indicators as to when the next release will drop. Tesla AI

GPT-4o (o for “omni”) is the first model to come out of the omni team, OpenAI’s first natively fully multimodal model. This launch was a huge org-wide effort, but I’d like to give a shout out to a few of my awesome team members who made this magical model even possible!

SpaceX might exceed 90% of all Earth payload to orbit later this year. Once Starship is launching at high rate, probably >99%. Has to be or we can’t build a city on Mars or base on moon. We file almost no patents, so nothing stopping competition from copying us.

Curious to see how this fits into the broader GitHub Copilot strategy, but I’ll say this: as someone who has been programming for 35 years, in a large miner of platforms: AI-assisted software development is a wave most still don’t understand the implications of.

Despite loss of many tiles and a damaged flap, Starship made it all the way to a soft landing in the ocean! Congratulations SpaceX team on an epic achievement!!

There's a stunning, simple explanation behind matrix multiplication. This is the first time this clicked on my brain, and it will be the best thing you read all week. Here is a breakdown of the most crucial idea behind modern machine learning: 1/15

A quick tech demo of a system I'm building for multi-modal multi-stage reasoning on complex web-based tasks: The only instruction it's given here is "Book a table at Felix Sydney for 2 on the 20th June at 12pm" - incredible! #gpt4 OpenAI techAU Logan Kilpatrick Bindu Reddy

This will be remembered as the point that everything changed. Not only do models reason, but general-purpose reasoning capability underpins everything - and we’re watching it emerge in real time.

Inspired by people creating an 'OS' using GenAI tools (which they weren't - they were react apps that looked like an OS GUI), I wanted to push the limits: I present AlixOS, a fully vibe-coded *real* 64-bit OS, created using OpenAI 's Codex in 5 days. youtu.be/kWhET8HyCgk
