Language Equality has a Price: A Systematic Investigation of Multi-turn LLM Performance for EU-24+

Sherzod Hakimov, Karl Osswald, Jelle Psurek +3

We evaluate large language models (LLMs) as language agents playing goal-directed dialogue games in self-play across 30 languages: the 24 official EU languages plus six others. Unl…

The Perfect Blend: Redefining RLHF with Mixture of Judges

Tengyu Xu, Eryk Helenowski, Karthik Abinav Sankararaman +17

Reinforcement learning from human feedback (RLHF) has become the leading approach for fine-tuning large language models (LLM). However, RLHF has limitations in multi-task learning…
