Elon Musk’s Grok is poised to swerve rivals’ plans to ‘watermark’ all artificially-generated content, City AM understands, after refusing to sign up to a European push forcing firms to make AI content traceable. xAI was the only major large language model maker to shun a European Union-led move to tighten AI transparency rules that means the likes of Anthropic, Google and OpenAI’s responses will contain an invisible watermark. However, Musk’s AI firm will still have to comply with applicable requirements under the EU AI Act, and so could eventually be made to introduce its own system for marking AI-generated material despite staying outside the code.
