Boris Power Recreates Chess Tactics Site With GPT-6 Astra

Boris Power, Head of Applied Research at OpenAI, posted that he recreated a chess tactics website inspired by one that ran from 2005 to 2017. He stated GPT-6 Astra handled the full build perfectly in a single prompt and extended the project to Go. The resulting site offers fast tactics for both games, one account with separate evolving ratings, mobile-friendly problems, instant moves, and background saving, according to the post and the linked site description.
