Incentives Really interesting look at how OpenAI has evolved it’s AI to begin to win team battles in Dota 2. Let’s just hope that it’s never released into the wild with the “team spirit” hyperparameter set to 1… OpenAI Five does not contain an explicit communication channel between the heroes’ neural networks. Teamwork is controlled by a hyperparameter we dubbed “team spirit”. Team spirit ranges from 0 to 1, putting a weight on how much each of OpenAI Five’s heroes should care about its individual reward function versus the average of the team’s reward functions. We anneal its value from 0 to 1 over training.
