MuPPET: A Benchmark for Contextual Privacy of LLM Assistants in Multi-Party Conversations

Elena Sofia Ruzzetti, Cornelius Emde, Sangdoo Yun +2

LLM agents are increasingly deployed in multi-party environments, handling sensitive personal data on behalf of individual users, for instance in group chats. When such an agent di…

MASEval: Extending Multi-Agent Evaluation from Models to Systems

Cornelius Emde, Alexander Rubinstein, Anmol Goel +4

The rapid adoption of LLM-based agentic systems has produced a rich ecosystem of frameworks (smolagents, LangGraph, AutoGen, CAMEL, LlamaIndex, i.a.). Yet existing benchmarks are m…

Privacy Collapse: Benign Fine-Tuning Can Break Contextual Privacy in Language Models

Anmol Goel, Cornelius Emde, Sangdoo Yun +2

We identify a novel phenomenon in language models: benign fine-tuning of frontier models can lead to privacy collapse. We find that diverse, subtle patterns in training data can de…

Dr.LLM: Dynamic Layer Routing in LLMs

Ahmed Heakl, Martin Gubri, Salman Khan +2

Large Language Models (LLMs) process every token through all layers of a transformer stack, causing wasted computation on simple queries and insufficient flexibility for harder one…

Leaky Thoughts: Large Reasoning Models Are Not Private Thinkers

Tommaso Green, Martin Gubri, Haritz Puerto +2

We study privacy leakage in the reasoning traces of large reasoning models used as personal agents. Unlike final outputs, reasoning traces are often assumed to be internal and safe…

C-SEO Bench: Does Conversational SEO Work?

Haritz Puerto, Martin Gubri, Tommaso Green +2

Large Language Models (LLMs) are transforming search engines into Conversational Search Engines (CSE). Consequently, Search Engine Optimization (SEO) is being shifted into Conversa…

Code-Switching Curriculum Learning for Multilingual Transfer in LLMs

Haneul Yoo, Cheonbok Park, Sangdoo Yun +2

Large language models (LLMs) now exhibit near human-level performance in various tasks, but their performance drops drastically after a handful of high-resource languages due to th…

Scaling Up Membership Inference: When and How Attacks Succeed on Large Language Models

Haritz Puerto, Martin Gubri, Sangdoo Yun +1

Membership inference attacks (MIA) attempt to verify the membership of a given data sample in the training set for a model. MIA has become relevant in recent years, following the r…

Direct Unlearning Optimization for Robust and Safe Text-to-Image Models

Yong-Hyun Park, Sangdoo Yun, Jin-Hwa Kim +5

Recent advancements in text-to-image (T2I) models have unlocked a wide range of applications but also present significant risks, particularly in their potential to generate unsafe…

TimeChara: Evaluating Point-in-Time Character Hallucination of Role-Playing Large Language Models

Jaewoo Ahn, Taehyun Lee, Junyoung Lim +4

While Large Language Models (LLMs) can serve as agents to simulate human behaviors (i.e., role-playing agents), we emphasize the importance of point-in-time role-playing. This situ…

Calibrating Large Language Models Using Their Generations Only

Dennis Ulmer, Martin Gubri, Hwaran Lee +2

As large language models (LLMs) are increasingly deployed in user-facing applications, building trust and maintaining safety by accurately quantifying a model's confidence in its p…

TRAP: Targeted Random Adversarial Prompt Honeypot for Black-Box Identification

Martin Gubri, Dennis Ulmer, Hwaran Lee +2

Large Language Model (LLM) services and models often come with legal rules on who can use them and how they must use them. Assessing the compliance of the released LLMs is crucial,…

Prometheus: Inducing Fine-grained Evaluation Capability in Language Models

Seungone Kim, Jamin Shin, Yejin Cho +8

Recently, using a powerful proprietary Large Language Model (LLM) (e.g., GPT-4) as an evaluator for long-form responses has become the de facto standard. However, for practitioners…
