There's a certain math meme that surfaces periodically on the internet (or one of its variants). It's nothing more but just computing some sums. So, here I ramble about it.

A while ago I did a little bit of a podcast episode on the OpenSSF model signing specification (OMS) and the AI/ML working group. It's now up at https://openssf.org/podcast/2026/07/14/whats-in-the-soss-podcast-65-s3e17-signing-the-future-s…

I am humbled and excited that the privacy-filter model we released last week is now trending as number 2 on HuggingFace, between giant models such as DeepSeek, Qw…
SHIPPED: My first release at @OpenAI with a ton of work from an awesome team: a privacy filter model that is small enough it can run in the browser while also pushing the frontier in the space. Also CLI tool to use model. Both under Apache…

I tested 80 models on two simple grid-based problems, asking them to locate 2026 and compute the sum of the neighbors when the numbers are placed in a spiral on the grid. The results surprised me, as models performed better on the problem …

Yesterday was my last day at Google. It was a bittersweet departure, leaving a team I really enjoyed working with. GOSST's mission is extremely important and I still believe in it.

Use `--yolo-mode`, Ralph, Gas Town, or any other automated tools? Beware of agent loops that run out of control. See a less dangerous example on https://github.com/google-gemini/gemini-cli/issues/16723
New year, new problems to test the LLMs on: arranging the numbers on a spiral, what is the sum of the neighbors of 2026? Read on for more details and some preliminary results, as well as how to suggest other LLMs to test: https://mihai.pag…
