Some 800 artists have signed an open letter accusing technology companies of "theft" of copyrighted work to train their artificial intelligence (AI) models. The letter demands that companies engage in "ethical" partnerships rather than "stealing." AI companies are facing multiple copyright lawsuits brought by artists and their representatives over the unauthorized use of copyrighted works to train AI models. Artists argue that the practice undermines their livelihoods and intellectual property rights, while companies claim it falls under "fair use." In a recent case, OpenAI faced backlash from Scarlett Johansson after its AI voice feature sounded similar to the actor's voice in a film.
