🔥 [New Paper] Semantic Richness or Geometric Reasoning?
❗️GPT-5.2, Gemini-2.5-Pro struggle on basic geometric tasks when semantic context is sparse.
❗️Performance is tied to data familiarity.
Conclusion: We are far from true visual invariance.

[1/2] The visual world is diverse—so why are the generative models stuck in a "one-patch-size-fits-all" architecture?

Meet Dynamic-DiT: A simple yet powerful technique that adaptively selects patch sizes based on how the latent manifold evolves at every denoising step.

Thrilled to share that our work investigating recurrence in trained ViTs has been accepted at #ICLR2026! 🎉

It turns out DINOv2 may be secretly recurrent.🦖

A 2-block recurrent transformer can match its activations layer-by-layer and recover 96% of its ImageNet performance.

[1/4] 🧠 The Great Modality Test: Are MLLMs Blind, Deaf, or Both?

Humans are perception pros: We instinctively know what information to trust.

Blindfolded, you describe the chirping birds.

Headphones on, you focus entirely on the silent visuals.

We robustly use the available and reliable modality.

Can SOTA MLLMs do the same?

We put the best Multimodal LLMs to the ultimate test.

[Deepti Ghadiyaram @deeptigp]

📢📢 Can we automate how humans instantly perceive if a generated video captures a human action done wrong?

Details: https://t.co/vV2T1EG0zX

Paper: https://t.co/18H8t5niJW

Our key idea is to build a manifold of correctly performed actions from several real-world videos. Next, we measure how far off a generated video is from this manifold to get a robust measurement of action correctness.

We perform extensive subjective, quantitative, and quantitative evaluation of different actions, generative models, and MLLMs.

Work done by @xavierohan Youngsun, Ananya, and Audrey

🕳️🐇Into the Rabbit Hull – Part I (Part II tomorrow)

An interpretability deep dive into DINOv2, one of vision’s most important foundation models.

And today is Part I, buckle up, we're exploring some of its most charming features.

[Xavier Thomas (Rohan) @xavierohan]

@gokulp01 Congrats!!

[Thomas Fel @thomas_fel_]

At ICML for the next 2 days to present multiple works, if you're into interpretability, complexity, or just wanna know how cool @KempnerInst is, hit me up 👋

I started shooting my new show "Conan O'Brien Must Go" and I can't wait to finish it after the writers' strike. Here's a sneak peek:
