Let's build hyper-personalized AI-powered software that avoids the attention hijacking anti-patterns that defined so much of the last decade of software design - here's our manifesto with principles on how we can do that

What if technology didn’t feel so… hollow? Some friends and I just released a manifesto about a world where tech leaves us feeling nourished (along with an evolving list of theses about how we can build it) https://t.co/sfKBVZ2zXr

Four new models from Mistral today - all Apache 2 licensed, all vision-capable, and one of them is a 3GB model that can run in a web browser and answer questions about things it can see through the webcam!

Five new Mistral models today, but the one I'm most excited about is this tiny 3B model that has vision support and can run entirely in a browser!

NEW: @MistralAI releases Mistral 3, a family of multimodal models, including three start-of-the-art dense models (3B, 8B, and 14B) and Mistral Large 3 (675B, 41B active). All Apache 2.0! 🤗 Surprisingly, the 3B is small enough to run 100% locally in your browser on WebGPU! 🤯

This is so wild... the leaked Opus soul document has now been confirmed! I wrote some initial notes about it on my blog https://t.co/tkOSAU663a - I like how it opens with this section about Anthropic themselves:

I just want to confirm that this is based on a real document and we did train Claude on it, including in SL. It's something I've been working on for a while, but it's still being iterated on and we intend to release the full version and more details soon.

A tiny TIL: if you get "Error 153: Video player configuration error" on YouTube videos embedded on your site a likely culprit is sending the "Referrer-Policy: same-origin" HTTP header Switching to "strict-origin-when-cross-origin" fixed it for me: https://t.co/4rSGiI1OVC

Pulled other some fun quotes from the early months of ChatGPT on my blog, OpenAI really did not expect it to be as popular as it was!

Happy 3rd birthday, ChatGPT. I was at Google then, leading two products: AI Test Kitchen and NotebookLM (there was no Bard/Gemini yet). We had launched AITK much earlier than ChatGPT, but it was a heavily constrained experience in comparison. It was a cool demo of LaMDA but

language interfaces are going to be a big deal, i think. talk to the computer (voice or text) and get what you want, for increasingly complex definitions of "want"! this is an early demo of what's possible (still a lot of limitations--it's very much a research release).

One of the underrated things about LLMs for coding is that they make writing code on a mobile phone more feasible I can build small but useful pieces of software entirely on my phone now - without even needing to pay full attention, so it's compatible with being out in the world

The Netflix number is five years old and the ChatGPT number pre-dates GPT-5 by a couple of months so there are plenty of caveats here, but I expect the order of magnitude remains about correct

Out of curiosity I decided to try and run the numbers on how much Netflix you can watch for the energy cost of a ChatGPT prompt As far as I can tell it's between 5.1 and 10.2 seconds, depending on which end of the 2019 IEA Netflix energy usage estimate you use
