CTO & co-founder @v7labs. Reliable AI agents at work, strange small models and weird interfaces for fun. I build everything I write about.

I trained an AI model to autocomplete my piano prompts.

Here’s what happens when I give it the first few notes:

TIL that WebGPU only guarantees 8 storage buffers per shader stage. Chrome lets me use 10+, but Firefox limits it to 9, on the exact same GPU.

Of course my shaders need 10 😅

Guess I'll have to pack a few buffers together.

Moved house and my headless Raspberry Pi was still looking for the old Wi-Fi. Couldn't face digging a keyboard out of a moving box, so I made my Mac broadcast the old SSID and password, waited for the Pi to join, SSH'd in and switched it over 😅

@OpenAI It's a 360M model running in your browser, pretending to be a shell. Try it here: https://t.co/UixTDbFeLG

[Simon Edwardsson @SimEdw]

@OpenAI If you need a fake shell as well, let me know 😅

Arc is shutting down, so if you're looking for a slightly different kind of browser...

Spegel uses an LLM to turn any website into clean markdown, right in your terminal. 😅

pip install spegel

@askmaddyy Glad you liked it!

[Simon Edwardsson @SimEdw]

@stevencheng 😅

@superdoccimo Very cool to see you trying to reproduce it. Will share full weights in a few days, instead of just int4.

[Simon Edwardsson @SimEdw]

@_figarroh_ Sorry about that, if you dm me your email I’ll delete it tonight and fix the bug!

How did you find it?

[Simon Edwardsson @SimEdw]

@maxbittker @DimitrisPapail @VaishShrivas I missed that one, thanks for sharing.

[Simon Edwardsson @SimEdw]

Trained a 360M model to pretend to be a terminal. There's no real shell behind it, but it runs vim, tmux and snake, and mostly remembers your files 😅

[Simon Edwardsson @SimEdw]

@ChadNauseam Thank you!

[Simon Edwardsson @SimEdw]

@vitobotta You can actually try it in the browser!

But yes. I tried `open index.html` and it spat out hex code. When I decoded it, it was actually html, not sure how that happened.

[Simon Edwardsson @SimEdw]

Me: Mum, can we have a world model?
Mum: We have a world model at home.
World model at home:

@maxbittker Thank you, Max! Really appreciate it.

I did spend a few months on this, on and off, and then wrote up the whole thing over the course of ten days. There were a lot of failed attempts along the way 😅

[Simon Edwardsson @SimEdw]

@yibie 谢谢！

You can read about it and test it here: https://t.co/UixTDbFMBe

It's a 208 MB download and runs best in Chrome on a laptop.

@AlexKontorovich @3blue1brown Thanks for posting. I see so many parallels to software engineering and can only assume that, as time goes on, more and more groups will have to face very similar challenges in their industries

Very well thought through outline of the future of maths. I see so many parallels to software engineering and can only assume that, as time goes on, more and more groups will have to face very similar challenges

[Alex Kontorovich @AlexKontorovich]

I’m very opinionated. So it’s nearly impossible for me to hear someone’s arguments and *not* find something I disagree with. (This includes reading things I myself wrote years - or weeks - ago.) And yet the amazing Grant Sanderson @3blue1brown has put out a long, detailed video on the future of mathematics, in which I cannot find a single flaw. I’ll be sending this to every PhD student and postdoc I know, and strongly recommend everyone watch it.

(Of course I tried to say many of the same things in my conversation with Thomas Koberda. But Grant’s version, unsurprisingly, does an infinitely better job at communicating those ideas!)
