What does an LLM think of you? LLMs pick up the slightest implicit cues about users. Often, they refuse to say who they think the user is. In our new preprint, we show how to read and change these hidden beliefs. Turns out they even affect whether the model refuses New paper🧵

📣 New preprint: Replay on Demand (RoD) Imagine you had 10 hours to refresh everything you learned in school. Would you divide them equally across every subject? Probably not. You’d spend your limited time on what you’ve forgotten most. 🧵 arxiv.org/abs/2609.40089

📣 Introducing MedKIT, our new benchmark for knowledge integration in LLMs, accepted at #NeurIPS2026! 🧵 Why recalling updated facts ≠ integrated knowledge and why we need methods that can bridge this gap: 📄 arxiv.org/abs/2609.38543

A medical LLM can give the right answer for the wrong reasons. Delighted our work is now published in Nature Communications Medicine — evaluating 8 LLMs on 1,269 unstructured seizure descriptions, with a practical guideline to use AI in clinical setup 🧵 doi.org/10.1038/s43856-026-0…

Accurate reward guidance in diffusion models has been a long-standing challenge. We propose Diamond Maps 💎, through stochastic flow maps we make reward guidance both accurate and scalable.

🚨 New paper! arxiv.org/abs/2603.06610 Are you sure your post-trained LLM isn’t forgetting something? Adapting LLMs is known to cause forgetting. We usually measure it via general knowledge benchmarks. But if MMLU doesn’t drop…. are you really fine?

Check out our new work on getting more out of your Vision Transformers without fine-tuning by leveraging intermediate representations when probing! We find that attentive probing is most robust for fusing across layers while showing exactly which layers matter for what task 👇
Why you should probe more than just the final layer of your Vision Transformer to maximize performance. 🧵👇

Excited to be in San Diego at #NeurIPS2025 this week. We'll be presenting Noise Hypernetworks at Hall C,D,E #3605 Thu 4 Dec 11am! If you're interested in Diffusion/Flow Matching or Reward Alignment, I'd love to chat! Feel free to DM me if you'd like to connect.
Reward hacking is challenging when fine-tuning few-step Diffusion models. Direct fine-tuning on rewards can create artifacts that game metrics while degrading visual quality. We propose Noise Hypernetworks as a theoretically grounded solution, inspired by test-time optimization.

How can we circumvent data scarcity in the time series domain? We propose to leverage pretrained ViTs (e.g., CLIP, DINOv2) for time series classification and outperform time series foundation models (TSFMs). 📄 Preprint: arxiv.org/abs/2506.08641 💻 Code: github.com/ExplainableML/TiV…
