Are AI agents shape rotators? In this new benchmark, we let the models play campaign puzzles in Opus Magnum, a puzzle game by @zachtronics. Ironically, Claude Opus 4.8 performed poorly, being beaten by GPT-5.5, Gemini 3.5 Flash, and GLM 5.2. Claude Fable 5 crushed them all.

Flux team 100% saw that tweet about @karpathy's crazy idea of training an image model on screenshots of all of the web instead of an LLM on HTML and ran with it. @bfl_ml

forget about generating HTML with a LLM "screenshot from a 1992 website on geocities, website of an amateur witch" "screenshot from a 2005 website, website of an amateur witch"

As some of you have noticed, avoid “boomer prompts” with o-series models. Instead, be simple and direct, with specific guidelines. Delimiters (xml tags) will help keep things clean for the model, and improve output. Read the full best practices guide: platform.openai.com/docs/guides/re…

Just learned that Yoshiki has passed away and so many people seem to love his ideas, I’m gonna thread a few here. An app builder on the iPhone where you start by describing the data structures you want in JSON and then nudge it towards a GUI

I've been jamming on this concept for making data-driven designs. Given some JSON, this app will provide you with an interface to describe how you want each entry styled, allowing you to gradually create a more complicated design. Here I create an airbnb-ish app.

this kinda feels like a parody, what is this benchmark? Why are the charts so vibey? In case I'm wrong though... brampton

You ever think about how everything you're doing on your computer is just a bunch of abstractions on top of 1s and 0s? Isn't that the most insane thing ever? Who thought of that? What?

I've been testing GPT-4.5 for the past few days, and this is basically the vibe I got. I love it for its "gut intuition." It picks up on and notices things that I wouldn't predict, or wouldn't have thought to ask for. GPT-4.5 is actually more booksmart and streetmart than

I'm thrilled to FINALLY publish scalingsynthesis.com, a living hypertext notebook outlining my research with @balOShere and @JoelChan86 discussing how Tools for Thought can facilitate synthesis. Click around and see where it takes you!

I'm thrilled to announce a research project on the creation of decentralized discourse graph tools for thought to promote synthesis with @JoelChan86 and @graphprotocol! More details in the thread on what that means and what our core questions are 👇️x.com/graphprotocol/…

YouTubers found @websim_ai last week and there have been lots of great videos popping up but this is one of my favorites. She’s a musician with maybe one other video that has anything to do with AI, her channel is pretty much all music. And now she’s making her own music tools.

My father-in-law is a large language model. We were looking at the Xbox home screen and I asked him what it would cost to build it today. I will never forget his answer… “We can’t, it’s too far out of distribution.”

o1 became obsolete in @websim_ai the moment o3-mini-high came out. It's faster than o1, and often a more powerful coder than Claude 3.5 Sonnet. Consistently high quality outputs, and less than a 7th of o1's costs. With o3-mini-high, I was able to make a 3d falling sand sim on

This probably works, but it’s also kind of sad. I think you’ll miss out on the model’s genius if this is on every prompt.

I dream of a world where apps that are basically a UI on top of a spreadsheet or database give you access to the database and let you query/edit from there
