PRInTS: Reward Modeling for Long-Horizon Information Seeking

arXiv:2511.19314v2 Announce Type: replace-cross Abstract: Information-seeking is a core capability for AI agents, requiring them to gather and reason over tool-generated information across long trajectories. However, such multi-step information-seeking tasks remain challenging for agents backed by language models. While process reward models (PRMs) can guide agents by ranking candidate steps at test-time, existing PRMs - designed for short reasoning with binary judgment - cannot capture richer dimensions of information-seeking steps, such as tool interactions and reasoning over tool outputs, n

Why this matters
Why now

The increasing sophistication and widespread deployment of AI agents necessitate more advanced reward modeling techniques to handle complex, multi-step information-seeking tasks, moving beyond simpler short-reasoning models.

Why it’s important

This development improves autonomous AI agent capabilities, directly impacting their effectiveness in complex real-world problem-solving and white-collar automation, making them more reliable and broadly applicable.

What changes

AI agents will be able to manage longer, more intricate information-seeking trajectories and complex tool interactions, leading to more robust and higher-quality outputs than previously possible.
