Chain-of-Frames: Advancing Video Understanding in Multimodal LLMs via Frame-Aware Reasoning
Sara Ghazanfari, Francesco Croce, Nicolas Flammarion +3
Recent work has shown that eliciting Large Language Models (LLMs) to generate reasoning traces in natural language before answering the user's request can significantly improve the…
On the Adversarial Robustness of Discrete Image Tokenizers
Rishika Bhagwatkar, Irina Rish, Nicolas Flammarion +1
Discrete image tokenizers encode visual inputs as sequences of tokens from a finite vocabulary and are gaining popularity in multimodal systems, including encoder-only, encoder-dec…
On the Out-of-Distribution Generalization of Reasoning in Multimodal LLMs for Simple Visual Planning Tasks
Yannic Neuhaus, Nicolas Flammarion, Matthias Hein +1
Integrating reasoning in large language models and large vision-language models has recently led to significant improvement of their capabilities. However, the generalization of re…
HalluHard: A Hard Multi-Turn Hallucination Benchmark
Dongyang Fan, Sebastien Delsad, Nicolas Flammarion +1
Large language models (LLMs) still produce plausible-sounding but ungrounded factual claims, a problem that worsens in multi-turn dialogue as context grows and early errors cascade…
OS-Harm: A Benchmark for Measuring Safety of Computer Use Agents
Thomas Kuntz, Agatha Duzan, Hao Zhao +4
Computer use agents are LLM-based agents that can directly interact with a graphical user interface, by processing screenshots or accessibility trees. While these systems are gaini…
Selective Induction Heads: How Transformers Select Causal Structures In Context
Francesco D'Angelo, Francesco Croce, Nicolas Flammarion
Transformers have exhibited exceptional capabilities in sequence modeling tasks, leveraging self-attention and in-context learning. Critical to this success are induction heads, at…
