YouTuber David Millette accuses OpenAI of using his videos to train their AI without consent.
OpenAI used Whisper, a speech recognition system, to transcribe millions of hours of YouTube videos.
OpenAI allegedly violated YouTube's terms of service by using content for "independent" applications.
Millette's lawsuit joins a growing list of legal actions against AI companies.
Google was aware of OpenAI's actions but hesitated to take action due to similar practices.
Millette seeks $5 million and an injunction to stop OpenAI from using his content.
The case hinges on the argument of unfair competition and unjust enrichment.
This case could set a precedent for future legal battles between AI companies and content creators.
