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:

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

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.

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)

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?)

I know the upcoming film version of the Odyssey is controversial, so I whipped together a completely accurate version that I think will be happily accepted by everyone as the most definitive version since Homer's original, if not more so.

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.

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.

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.

Fine, you all want to code like this I guess. (Runway's new Agent mode is quite impressive, doing fairly complex story building from just a short text description of what you want. Not error free obviously, but this was pretty great for a one-shot attempt)

Had early access to GPT-5.4 and Pro. They are very good. One fun illustration of progress, this is the same prompt I used in GPT-4 below (making a 3D space inspired by Piranesi) now in GPT-5.4 Pro. There were no errors, made in a single prompt plus one to "make it better."

Less than a year later, Lennart (a well-known GTA modder) rebuilt this with Nano Banana Pro, which is good enough that it can generate GTA car textures with no need for human adjustments. He also made a Claude skill that automatically builds, deploys & tests them in-game.
