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.”
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.
