OpenAI Five is a computer artificial intelligence (AI) research program developed by OpenAI, a San Francisco-based non-profit research firm. It is a team of five AI bots that are capable of playing a game of Dota at a high level of skill.
OpenAI Five is a team of five AI bots trained using deep learning neural networks and reinforcement learning techniques, which enable them to learn how to achieve a given goal, such as playing a game of Dota. The bots have been trained to play the game from scratch, without any prior knowledge of the rules or the environment. The bots use a variety of techniques to learn the game, including convolutional neural networks, long short-term memory, and imitation learning. Their behavior is also shaped by a set of rules called “micro-decision rules,” which define their behavior in various situations.
OpenAI Five is notable for its ability to defeat professional teams of human players in the multiplayer online battle arena (MOBA) game, Dota 2. In 2018, OpenAI Five defeated a team of professional Dota 2 players in a series of five matches. In 2019, they won the OpenAI Five Finals, a five-game series of Dota 2 against professional players led by former The International champions.
The research program has been significant in terms of advancing artificial intelligence research as a whole. OpenAI Five has furthered development in reinforcement learning, system dynamics, game theory, and artificial intelligence by providing an open platform for research. Other research applications of OpenAI Five include robotics, machine vision, natural language processing, and autonomous systems.
