Can generative image models be good world models?
This work from @Meta FAIR shows that there is a tradeoff between realism and diversity.
The more realistic a generative model becomes, the less diverse it becomes.
Realism comes at the cost of coverage.
In other words, the most realistic systems are mode-collapsed.
My hunch, supported by a growing amount of empirical evidence, is that world models should *not* be generative.
They should make predictions in representation space.
In representation space, unpredictable or otherwise irrelevant information is absent.
This is the main argument in favor of JEPA (Joint Embedding Predictive Architectures).

Are sota image generative models effective world models? Consistency-diversity-realism Pareto fronts show they're not (yet): - No model dominates others as a world model - Improvements in quality and consistency have come at the expense of diversity 🔗 arxiv.org/abs/2406.10429

Your premise is false.
Intelligent systems require the ability to reason and plan.
Reasoning and planning involve a search for solutions (actions) that minimize objectives.
Those objectives measure not only whether the imagined actions fulfill a goal but also whether a number of guardrails are satisfied.
By construction, such a system can not produce any action that will violate the guardrails, according to the predictions of its internal world model.
I call this objective-driven AI.
The question becomes one of designing appropriate guardrails.
We are familiar with that.
It's like making laws.
Except that objective-driven systems will be completely unable to violate these laws (unlike humans).

Here's my conversation with Sam Altman (@sama), his 2nd time on the podcast. We talk about the board saga, Elon lawsuit, Ilya, Sora, GPT-5, $7 trillion in compute, open source, and AGI. This was a truly fascinating conversation.
It's here on X in full, and is up on YouTube, Spotify, and everywhere else. Links in comment.

Ever asked yourself what's the best explainability method for ViT Transformer at the moment?
🚨 We present you LeGrad, a Layerwise Explainability GRADient method for large ViT transformer architectures. 🚨
So, grab your ☕️ and 🥐, release your inner 🇫🇷, and join us on our journey through the layers of different ViT models.
Authors: @BousselhamWalid did all the programming, but we would have been lost without the wisdom of @angie_boggust and @hen_str ! Thanks so much for being so great collaborators!
