Building Dota Bots That Beat Pros - OpenAI's Greg Brockman, Szymon Sidor, and Sam Altman

Summary

OpenAI's Greg Brockman, Szymon Sidor, and Sam Altman discuss the process of building Dota bots that can beat professional players. They emphasize the importance of engineering and scaling algorithms, as well as the use of image classification and fixing bugs in code. The team converted a scripted bot from Lua to Python and implemented a protocol to handle game state and API calls. They trained the bots using reinforcement learning and made continuous improvements to their performance. The bots received mixed reactions from professional players, with some finding them valuable for improving gameplay. OpenAI recognized the limitations of the bot's learning environment and organized a LAN party to expose it to new challenges. The team also discussed the importance of fixing exploits and making tweaks to the bot's item builds. The bots were able to beat professional players, but there were instances where humans found strategies to exploit their weaknesses. The development process involved intense timelines and last-minute adjustments. Technical skills such as engineering, linear algebra, and basic statistics were crucial, and a PhD in AI was not necessary to work at OpenAI. The video also touched on the relevance of playing video games in building AI systems and the potential ethical issues surrounding AI.
