A team of finalists at the OpenAI Codex Hackathon won $10,000 by developing Yolodex, an end-to-end game vision factory. Their pipeline automates video analysis, extracting frames and auto-labeling objects with Codex agents to create a training-ready YOLO dataset in minutes, significantly reducing the time needed for manual labeling. The innovative demo was presented to tech leaders, including Sam Altman. Demonstration and repository links provided.
