CityLearn provides a modular simulation platform for energy management research using reinforcement learning. Users can define multi-zone building clusters, configure HVAC systems, storage units, and renewable sources, then train RL agents against demand response events. The environment exposes state observations like temperatures, load profiles, and energy prices, while actions control setpoints and storage dispatch. A flexible reward API allows custom metrics—such as cost savings or emission reductions—and logging utilities support performance analysis. CityLearn is ideal for benchmarking, curriculum learning, and developing novel control strategies in a reproducible research framework.

LLM Arena is a versatile platform designed for comparing different large language models. Users can conduct detailed assessments based on performance metrics, user experience, and overall effectiveness. The platform allows for engaging visualizations that highlight strengths and weaknesses, empowering users to make educated choices for their AI needs. By fostering a community of comparison, it supports collaborative efforts in understanding AI technologies, ultimately aiming to advance the field of artificial intelligence.

MADDPG-Keras delivers a complete framework for multi-agent reinforcement learning research by implementing the MADDPG algorithm in Keras. It supports continuous action spaces, multiple agents, and standard OpenAI Gym environments. Researchers and developers can configure neural network architectures, training hyperparameters, and reward functions, then launch experiments with built-in logging and model checkpointing to accelerate multi-agent policy learning and benchmarking.
