-PufferLib is the reinforcement learning library I wish existed during my PhD. It started as a compatibility layer to make working with complex environments a breeze. Now, it's a high-performance toolkit for research and industry with optimized parallel simulation, environments that run and train at 1M+ steps/second, and tons of quality of life improvements for practitioners. All our tools are free and open source. We also offer priority service for companies, startups, and labs!
+PufferLib is a fast and sane reinforcement learning library that can train tiny, super-human models in seconds. The included learning algorithm, hyperparameter tuning, and simulation methods are the product of our own research. All our tools are free and open source. Need a high performance environment for your application? We build them professionally and offer training + extended support. Contact jsuarez🐡puffer🐡ai.
