Elon Musk has filed a lawsuit against the artificial intelligence company OpenAI, accusing it of violating a contract and misusing his company’s technology. The lawsuit, filed in a California court, alleges that OpenAI violated a contract by allowing the release of GPT, the language model that powers ChatGPT. Musk co-founded OpenAI in 2015 but left the company in 2018. The lawsuit claims that OpenAI used technology developed by Musk’s companies, including Tesla, without proper authorization. Musk is seeking financial compensation and a court order that would prevent OpenAI from using the technology. The lawsuit renews Musk’s claims against OpenAI, which he has accused of misusing his intellectual property. OpenAI has not yet responded to the lawsuit, but the company has previously denied Musk’s allegations.
