When should I choose PufferLib over Stable-Baselines3?

Use PufferLib when your priority is speed, scale, or multi-agent support. Choose Stable-Baselines3 for quick prototyping of standard algorithms where throughput is not the primary bottleneck.

What is the PufferLib Ocean suite?

The Ocean suite is a collection of over 20 pre-built, high-performance environments included with PufferLib, designed for immediate training and benchmarking.

What makes PufferLib faster than other RL libraries?

PufferLib uses optimized vectorization, shared memory buffers, and a high-performance PPO+LSTM implementation (PuffeRL) to achieve 2-10x speedups over standard implementations like Stable-Baselines3.

Can I use my existing Gymnasium environments with PufferLib?

Absolutely. PufferLib includes emulation wrappers that allow you to seamlessly vectorize and accelerate standard Gymnasium environments for much faster training.

Does this skill support multi-agent reinforcement learning?

Yes, PufferLib provides native support for multi-agent systems and integrates directly with PettingZoo, allowing for high-performance training of cooperative or competitive agents.
