Quantifying Overclaiming Propensity in Frontier LLM Agents

Nolan Smyth, Yorguin-Jose Mantilla-Ramos, Pascal Jr Tikeng Notsawo +6

Frontier coding agents are increasingly trusted to work autonomously for long periods of time, yet what they actually did is often hard to tell from their final response. We quanti…

Position: Collusion Risks Among AI Reasoning Agents Justify Certification Requirements for Making Market Decisions

Matthew Riemer, Tommaso Tosato, Amin Memarian +4

This position paper argues that AI agents with chain-of-thought reasoning capabilities are predisposed to exhibit collusive behavior and should be required to obtain behavioral cer…

Activation Steering for Aligned Open-ended Generation without Sacrificing Coherence

Niklas Herbster, Martin Zborowski, Alberto Tosato +2

Alignment in LLMs is more brittle than commonly assumed: misalignment can be induced by adversarial prompts, benign fine-tuning, emergent misalignment, and goal misgeneralization.…

Tommaso Tosato, Saskia Helbling, Yorguin-Jose Mantilla-Ramos +5

Large language models require consistent behavioral patterns for safe deployment, yet there are indications of large variability that may lead to an instable expression of personal…
