Comparing Reinforcement Learning Methods

A comparative overview of various RL approaches for interactive agents.

Method Description Key Advantage Key Disadvantage
LOOP (Our Approach) PPO with Leave-One-Out baseline and per-token clipping
  • Memory efficient (single LLM in memory)
  • Sample-efficient (reuses off-policy samples)
  • Achieves SOTA on AppWorld
  • Requires careful hyperparameter tuning
  • Can be sensitive to reward normalization
PPO (Learned Critic) Standard PPO using a value network for advantage estimation
  • Token-level advantages
  • Potentially better credit assignment
  • Training instability
  • Hyperparameter sensitivity
  • Slow & memory-intensive value network
RLOO (REINFORCE Leave-One-Out) On-policy REINFORCE variant with sampling-based advantage
  • Simpler, avoids separate critic LLM
  • Competitive performance in specific domains
  • Inefficient (on-policy updates)
  • Does not amortize rollout cost
SFT-GT (Supervised Fine-Tuning) Fine-tuning on ground-truth human-generated trajectories
  • Direct learning from optimal paths
  • Simple implementation
  • Poor generalization outside training data
  • Limited recovery capabilities for errors

Foundation Model for Interactive Agents

Details on the underlying LLM architecture used for the LOOP agent.

Qwen2.5-32B Base LLM Parameters for LOOP Agent

The LOOP agent is built on a Qwen2.5-32B-Instruct base model and fine-tuned using LoRA (Low-Rank Adaptation), which makes training memory-efficient and straightforward, akin to fine-tuning a single LLM. This approach allows for effective training even with limited computational resources.

Emergent Behaviors from RL Training

How the LOOP agent's behavior adapts and improves through reinforcement learning.

Learning to Consult API Documentation

RL training significantly increased the agent's tendency to query API documentation before invoking functions. This proactive information-gathering mitigates unwarranted assumptions and confabulation, leading to more robust and accurate task execution.

Impact: API documentation queries increased by ~60%.

Avoiding Suboptimal Open-Loop Control

The agent learned to avoid batching multiple code cells for execution, preferring an interactive, step-by-step approach within the REPL. This 'read-eval-print loop' control leads to better decision-making by incorporating intermediate results.

Impact: Prevalence of multiple code cells per turn decreased by ~6x.

Improved Error Recovery and Resilience

Instead of giving up after encountering API errors, the trained agent learned to persevere, debug, and attempt recovery strategies. This resilience is critical for long-horizon tasks in complex, real-world digital environments.

Impact: Failed API call give up rate reduced by ~3x.
