Scaling In-Context Online Learning Capability of LLMs via Cross-Episode Meta-RL
Large Language Models (LLMs) excel at static prediction, but real-world decision-making demands online adaptation through interaction and delayed feedback. This paper introduces ORBIT, a novel multi-task, multi-episode meta-reinforcement learning framework that trains LLMs to learn effectively from in-context interaction.
Executive Impact: Empowering LLMs for Real-World Adaptation
ORBIT addresses a critical limitation of current LLMs: their struggle with online, interactive decision-making. By enabling learn-at-inference-time adaptation without weight updates, ORBIT transforms LLMs into dynamic, general-purpose agents capable of mastering new, unseen environments.

This paper pioneers a novel approach in Reinforcement Learning by demonstrating how Large Language Models (LLMs) can acquire and leverage online interaction experience for adaptive decision-making. Unlike traditional static models, ORBIT enables LLMs to perform in-context online learning across multiple episodes without requiring parameter updates, making them suitable for dynamic, real-world environments.
The core innovation lies in its multi-task, multi-episode meta-reinforcement learning framework, which trains LLMs to learn how to learn from interaction. This allows for sophisticated behaviors like balancing exploration and exploitation, and adapting strategies based on delayed feedback, all within the context window.

Success Rate Increase (Maze, Ep.3) with ORBIT vs. Base Model.
ORBIT (8B) achieves substantially higher success rates and, critically, continues to improve across successive episodes. This consistent upward trend indicates that the model effectively leverages interaction history stored in the context window to refine its behavior online.

ORBIT's Adaptive Exploration in Unseen Mazes
In a partially observable maze environment, where the agent relies only on local surroundings and cross-episode memory, ORBIT demonstrates remarkable adaptive exploration. After failing in early episodes (Ep 1-2), ORBIT spontaneously engages in deliberative exploration in Episode 3.
Instead of replaying unproductive behaviors, the agent reflects on past failures, summarizes interaction history, and strategically chooses actions to gather new information. This behavioral shift leads to actively exploring previously unvisited routes and successfully reaching the goal.
Quantitative evidence further supports that ORBIT significantly increases the number of newly explored states after failures, indicating it learns to "try something different" rather than cycling through local choices, a crucial capability for complex online decision-making.
