​While your AI agent codes, you meet the builders who are shaping what comes next.

​This isn’t just a hackathon. It’s your entry point into a top-tier network of Token Maxing engineers.

​While your agent works, you’re in the room with speakers, builders, and conversations you won’t find anywhere else.

​Ralphthon originated in Seoul as a 24-hour overnight format where builders set up agents, went to sleep, and woke up to what shipped. Then it scaled to SF with 150 builders, sponsored by OpenAI.

​Notable open-source contributions from previous editions:
