Do note that "reconstruction" is not the right word, the proper characterisation of that sort of imputation is "artist impression": good for situations where the precise details doesn't matter. Though of course if the details doesn't matter maybe blurry is fine.

I like that this one shows some "fails", and not just the top of the top results: For example, the surfer is surfing in the air at the end: https://cdn.openai.com/tmp/s/prompting_7.mp4 Or this "breaking" glass that does not break, but spills liquid in some weird way: https://cdn.openai.com/tmp/s/discussion_0.mp4 Or the way this person walks: https://cdn.openai.com/tmp/s/a-woman-wearing-a-green-dress-a...

Also, why does she have a umbrella sticking out from her lower back?

Earlier quoted context omitted.

You're talking about an agent with a world model used for planning. Actually generating realistic images is not really needed as the world model operates in its own compressed abstraction. Check out V-Jepa for such a system: https://ai.meta.com/blog/v-jepa-yann-lecun-ai-model-video-jo...

V-Jepa is actually super impressive. I have nothing but respect for Yann LeCun & his team, they really have been on a rampage lately.

One more French brain we didn't manage to keep.

The drain is just crazy at this point.

I suppose the lady usually has an umbrella in this kind of situation, so it felt the umbrella should be included in some way: https://youtu.be/492tGcBP568

That is creepy...

Take a look at these adorable kangaroos to relax:

Yesterday I was watching a movie on Netflix and thought to myself, what if Netflix generated a movie based on what I want to see and what I like.

Plus, it could generate it in real time and take my responses into account. I look bored? Spice it up, etc.

Today such a thing seems closer than I thought.

Ugh, AI generated images everywhere is already annoying enough. Now we're gonna have these factitious videos clogging up everything, and I'll have to explain my old neighbor that Biden did infact not eat a fetus again and again.

I’ve been dying for someone to make a Civilization AI. It might not be too crazy of an idea - would love to see a model fine-tuned on sequences of moves. The biggest limitation of video game AI currently is not theory, but hardware. Once home compute doubles a few more times, we’ll all be running GPT-4 locally and a competent Civilization AI starts to look realistic.

Would love to see someone to make an AI that can predict our economy, perhaps by modeling all the actors that participate in the economy using AI agents.

Do you have a list ?

I think people might be missing what this enables. It can make plausible continuations of video, with realistic physics. What happens if this gets fast enough to work _in real time_.

Tbh I don't think an AI for Civ would that impressive, my experience is that most of time you can get away with making locally optimal decisions I.e growing your economy and fighting weaker states. The problem with current civ AI is that their economies can be often structured nonsensically, but optimized economies is usually just the matter of stacking bonuses together into specialized production zones, which can be solved via conventional algorithms.
