X has updated its developer agreement to add a new restriction on using posts on the platform to train AI. The updated policy, spotted earlier by TechCrunch, says developers can’t use content from X or its API to “fine-tune or train a foundation or frontier model.”

The policy change could set up X to make AI training deals with third-party companies, similar to the deal Reddit struck with Google. Reddit, which has a similar policy to block AI crawlers, sued Anthropic on Wednesday over claims the company’s AI crawlers accessed the site more than 100,000 times since July 2024. Elon Musk’s AI company, xAI, acquired X for $33 billion on paper in March.

Though X’s developer agreement now bars companies from training AI on its content, its privacy policy still states that third-party “collaborators” can train AI models on the site’s data unless users opt out. X also feeds user data into its AI model, Grok, for training.
