arXiv:2607.03426v1 Announce Type: cross Abstract: Large language models (LLMs) exhibit strong reasoning and world-knowledge capabilities, yet often struggle to gather information effectively across the multi-turn interactions required in sequential decision-making settings. We introduce Amortised Sequential Information Gathering (ASIG), a fine-tuning approach that amortises Bayesian Experimental Design (BED) into LLM policies via a multi-turn extension of Group Relative Policy Optimisation with an Expected Information Gain reward. Evaluated on the 20 Questions task, ASIG more than doubles the
The increasing sophistication of LLMs and the recognition of their limitations in sequential decision-making tasks is driving research into more adaptive interaction modalities.
This development represents a significant step towards more autonomous and effective AI agents capable of complex, multi-turn reasoning and information gathering.
LLMs can now be fine-tuned to actively and sequentially seek out information, rather than passively generating responses based on initial prompts, dramatically expanding their real-world applicability.

LLMs will become significantly more effective in tasks like scientific discovery, complex problem-solving, and strategic decision support.
The improved agentic capabilities of LLMs will accelerate the automation of knowledge work, leading to new forms of human-AI collaboration and potentially displacing certain analytical roles.
The ability for AI systems to autonomously conduct research and gather information may lead to novel discoveries at an unprecedented pace, impacting various scientific and industrial sectors.
