What it does

AReaL provides a flexible reinforcement learning bridge for large language model-based agents, allowing founders to build and train custom AI agents

When to use it
  • •When you need to integrate reinforcement learning with large language models for complex decision-making tasks
  • •When you want to build custom AI agents that can learn from interactions and adapt to new situations
  • •When you require a flexible and modular framework for building and training AI agents
Ready-to-paste prompt
python examples/train_llm_agent.py --env CartPole-v1 --model-size large --training-steps 10000
Heads up: Make sure you have the necessary GPU resources and a compatible Python version (Python 3.8 or later) to run the AReaL framework, as specified in the README
