I've engineered a hand-crafted Transformer to do long-hand addition. All of the weights were hand-chosen by me. It is perfectly accurate.
How? Fall down the rabbit hole here: colab.research.google.com/gi…
Short on time? Here's a summary 👇
1/
Picked up an old hobby project because Codex is AGI.
Yesterday it built a 2.5GHz "spectrum analyzer" from a SERDES block on an old PicoEVB FPGA & worked out all the PCIe mumbo jumbo. Sees everything from WiFi to FM, all at once!
This would've taken me months. For Codex? 12hrs
I've been off and on involved with this for what feels like forever, and am so excited for it to see the light of day! This is the beginning of a whole new era of human to model communication.

the most predictive trait for successful research these days seems to be excessive carefulness, bordering on paranoia. so easy to make bugs, so hard to find them
agents, so far, mostly make this more difficult

I’m hiring on my team at OpenAI for Research Engineer / Scientist and Software Engineer roles.
I believe one of the most important questions for future AI systems is: how do we train them to help people over time?
We work on that through RLHF, post-training, reward modeling, long-horizon evals, and the data infrastructure behind personalized multimodal AI.

Hello wayward person on the internet trying to figure out why your UniFi router is convinced that your ISP (Starlink) is offline when it definitely isn’t. UniFi’s PHY link detection is overly neurotic—if you put a switch between things everything will work great. You’re welcome.
With no exaggeration—this is some of the most societally important work at OpenAI right now.
I've been driving the research for our collab with Jony Ive from w/in OpenAI for the last year, alongside the best team imaginable.

It's deeply concerning that one of the best AI researchers I've worked with, @kaicathyc, was denied a U.S. green card today. A Canadian who's lived and contributed here for 12 years now has to leave. We’re risking America’s AI leadership when we turn away talent like this.

Second ship of the day 📈
We're building ChatGPT into a contextual assistant.
If you're wondering why @openai is building macOS and PC apps—this the beginning of why.
Remember how in the TV show Severance, the main characters spend their entire workday staring at numbers and deciding if they're "good numbers" or "bad numbers" and we don't know why?
I've figured it out...
They are debugging numerics issues in large language models.

everyone wants to join a rocket ship until they remember they’re bumpy and on fire. buckle up y’all, only way to space.
The early chain of thought papers are what lead me to conclude that AI was going to work this time and MAN IS IT WORKING. This is an incredible achievement by even more incredible people 🙌
We're releasing a preview of OpenAI o1—a new series of AI models designed to spend more time thinking before they respond.
These models can reason through complex tasks and solve harder problems than previous models in science, coding, and math. openai.com/index/introducing…
So excited for this -- begone wrapping all your LLM calls in a while loop until the model decides to follow your schema. If you're building on the API, it's hard to a imagine a use case where this wouldn't benefit immensely.
Introducing Structured Outputs in the API—model outputs now adhere to developer-supplied JSON Schemas.

Fun fact: @barret_zoph moonlights as a table
I don't know who needs to hear this but:
You can replace that old monitor you keep around to plug into linux servers w/ a $30 HDMI -> USB Capture dongle and Quicktime.
