- Abstract: We study whether multiple large language models (LLMs) can autonomously
improve each other in a negotiation game by playing, reflecting, and
criticizing. We are interested in this question because if LLMs were able to
improve each other, it would imply the possibility of creating strong AI agents
with minimal human intervention. We ask two LLMs to negotiate with each other,
playing the roles of a buyer and a seller, respectively. They aim to reach a
deal with the buyer targeting a lower price and the seller a higher one. A
third language model, playing the critic, provides feedback to a player to
improve the player's negotiation strategies. We let the two agents play
multiple rounds, using previous negotiation history and AI feedback as
in-context demonstrations to improve the model's negotiation strategy
iteratively. We use different LLMs (GPT and Claude) for different roles and use
the deal price as the evaluation metric. Our experiments reveal multiple
intriguing findings: (1) Only a subset of the language models we consider can
self-play and improve the deal price from AI feedback, weaker models either do
not understand the game's rules or cannot incorporate AI feedback for further
improvement. (2) Models' abilities to learn from the feedback differ when
playing different roles. For example, it is harder for Claude-instant to
improve as the buyer than as the seller. (3) When unrolling the game to
multiple rounds, stronger agents can consistently improve their performance by
meaningfully using previous experiences and iterative AI feedback, yet have a
higher risk of breaking the deal. We hope our work provides insightful initial
explorations of having models autonomously improve each other with game playing
and AI feedback.

Many real dialogues are interactive, meaning an agent's utterances will influence their conversational partner, elicit information, or change their opinion.
We use this fact to rewrite and augment existing suboptimal data, and train via offline reinforcement learning (RL) an agent that outperforms both prompting and learning from unaltered human demonstrations.
Our results in a user study with real humans show that our approach greatly outperforms existing state-of-the-art dialogue agents.

Negotiation is the basis of social interactions; humans negotiate everything from the price of cars to how to share common resources.
With rapidly growing interest in using large language models (LLMs) to act as agents on behalf of human users, such LLM agents would also need to be able to negotiate.
We develop NegotiationArena: a flexible framework for evaluating and probing the negotiation abilities of LLM agents.

Large language models (LLMs) are effective at answering questions that are clearly asked.
When faced with ambiguous queries they can act unpredictably and produce incorrect outputs.
This underscores the need for the development of intelligent agents capable of asking clarification questions to resolve ambiguities effectively.

In a competitive game scenario, a set of agents have to learn decisions that maximize their goals and minimize their adversaries' goals at the same time.
We propose a novel model composed of three neural layers that learn a representation of a competitive game, learn how to map the strategy of specific opponents, and how to disrupt them.
Our experiments demonstrate that our model achieves better performance when playing against offline, online, and competitive-specific models, in particular when playing against the same opponent multiple times.
