OpenAI released the public beta of OpenAI Gym, a toolkit for developing and comparing reinforcement learning algorithms. The toolkit includes a suite of environments ranging from simulated robots to Atari games, along with a site for comparing and reproducing results. This represented a significant early infrastructure contribution to the RL research community.
OpenAI published research showing that evolution strategies (ES), a decades-old optimization technique, can match standard reinforcement learning performance on benchmarks like Atari and MuJoCo. The approach offers practical advantages over RL including easier parallelization and fewer hyperparameter sensitivities. This positions ES as a viable alternative training paradigm for policy optimization tasks.
