Kimi K3 on my shader test: "create a visually interesting shader that can run in twigl-dot-app make it like an infinite city of neo-gothic towers partially drowned in a stormy ocean with large waves." "Make it better" Very good model, not Sol Max or Fable, but great open weights

SeeDance 2.0: "An anime where an otter goes into a large mech, with lots of quick shots of mechanical parts and gears turning. The otter gives a grim thumbs up, and then pilots the mech, flying into battle against an octopus made of marble." Again, this was the very first try

Sold out! But I had Claude create and deploy all 80 volumes of The Weights to the site as well-formatted PDFs, so you can download them for free if you want. 58,276 pages in total. 117 million floating point numbers. This is everything that makes GPT-1.

The hardcover book of GPT-1’s weights that Claude Code designed, produced, and sold (including the cool cover which visualizes the numbers in the volume) actually came in the mail today and it looks really nice. I never touched any code or did any design or any API to make this.

My most popular Sora video was “an Elaborate regency romance where everyone is wearing a live duck for a hat (each duck is also wearing a hat), a llama plays a flute, prestige drama” I am not sure why OpenAI has decided their compute has more valuable uses. Really a mystery.

AI can help explain complex topics easily by throwing together a simulation. As Eric says later in the thread, a newer paper argues that this pattern is actually collider bias (the authors disagree). What is collider bias? Gemini one-shots an explanation:

"golden retriever running through a brutalist art gallery with modern art on the walls as a single red balloon floats overhead" in Sora, Kling (the best Chinese model), Runway (best American model). Best of 2 videos This is a hard prompt, so look at consistency, reflections, etc

Had early access to Gemini with Deep Think. Very good model, big gains over standard Gemini 2.5 Pro for a lot of problems. Here is the first attempt at the starship control panel prompt I try with every model. First time I have seen a model make a 3D interface in response.

One more Seedance version of "Monica's apartment from the show Friends, except all of the friends are otters wearing wigs. The otter with a Rachel wig says "Is anything weird" and the one with a Joey wig says "Nope, all is normal"." Attempt 2 of 2. The laugh track is something

I had early access to what is Claude 4 (I don't know which model) & I have been very impressed. Fun example, this is what it made in response to the prompt: "the book Piranesi as a p5js 3d space. do it for me" - just that, no other prompting (note the birds, water, lighting)

AI finally lets us see Raphael's The School of Athens the way Raphael obviously intended it, illustrating the delicate dance and subtle conflicts between Plato and Artistotle. (Seedance 2.0 is very fun to play with)

I had Fable build another thing I always wanted, a full procedural fantasy kingdom generator with economics, trade routes, population growth, wars, lineages, and occasional dragons. First, I worked with it on a plan, then it made it. You can play it here:

When GPT-5 came out, I created a procedural brutalist city builder as a demo (you can see it in the quoted tweet) I used GPT-5.6 Sol in Codex to do the same thing, touching no code. Less than a year... Play with it (its fun, if you like cities):

Fable: "Last and First Men is out of copyright. I want you to make a movie that features a reading of it with appropriate mixes of animation and images using access to the APIs you have (elevenlabs, hugging face) . Give me the first 10-15 minutes, ending at an appropriate break."

10 months later, I gave Claude Code with Fable the same brief, asking it to construct SimRefinery from surviving screenshots and documentation. Fully playable, with a learning mode & all sorts of sophistication. Look at the difference from the old version!

I know they are pivoting to health care(?!) but there is still nothing like Midjourney for making strange and atmospheric images and short animations in ways no other AI image generator can do. Here are some strange cities I made with similar prompts but very different styles.

I think people don't realize why Gemini Omni is different than other video AIs. It is fully multimodal, so it can edit video natively, too I took the famous "train " movie from 1896 & made it a bullet train, LEGO, added a time traveler, a centipede, muppets... (see reflections?)

Wow, diffusion models (used in AI image generation) are also game engines - a type of world simulation. By predicting the next frame of the classic shooter DOOM, you get a playable game at 20 fps without any underlying real game engine. This video is from the diffusion model.

Had Claude Code build a little plugin that visualizes the work Claude Code is doing as agents working in an office, with agents doing work and passing information to each other. New subagents are hired, they acquire skills, and they turn in completed work. Fun start.

This is a big leap forward to doing real data analysis with GPT-4o. It still can't quite handle the way many people use spreadsheets (Excel formulas, etc.) but it is pretty impressive. You can zoom into spreadsheets and ask about cells, modify graphs, etc. I trimmed 45 seconds.
