Learning When to Plan: Efficiently Allocating Test-Time Compute for LLM Agents

Davide Paglieri, Bartłomiej Cupiał, Jonathan Cook +6

Training large language models (LLMs) to reason via reinforcement learning (RL) significantly improves their problem-solving capabilities. In agentic settings, existing methods lik…

Gaia2: Benchmarking LLM Agents on Dynamic and Asynchronous Environments

Romain Froger, Pierre Andrews, Matteo Bettini +21

We introduce Gaia2, a benchmark for evaluating large language model agents in realistic, asynchronous environments. Unlike prior static or synchronous evaluations, Gaia2 introduces…

Training Language Models on Synthetic Edit Sequences Improves Code Synthesis

Ulyana Piterbarg, Lerrel Pinto, Rob Fergus

Software engineers mainly write code by editing existing programs. In contrast, language models (LMs) autoregressively synthesize programs in a single pass. One explanation for thi…
