Do VLMs truly reason or memorize data? We show ❗even transformations like rotation & scaling still throw them off ❗finetuning fails to generalize across domains tinyurl.com/colmbu26 📅 Stop by our poster on Wed @ 4:30 PM and chat with @xavierohan #COLM2026 @COLM_conf

Thank you @GoodfireAI for supporting my research group's research on interpretability of multi-modal LLMs. Excited to use Silico! 🚀

🔥 [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. More here: xthomasbu.github.io/visual_i…

[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.

[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.

📢📢 Can we automate how humans instantly perceive if a generated video captures a human action done wrong? Details: xthomasbu.github.io/video-ge… Paper: huggingface.co/papers/2512.0… 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
