Elon Musk’s social platform, X (formerly Twitter), has recently revised its developer agreement in a move primarily aimed at preventing developers from using legally obtained API data to train artificial intelligence models.
In the past, access to Twitter’s API was both free and remarkably convenient. However, following Musk’s acquisition of the platform, the API policy was overhauled—developers are now required to purchase access at a considerable cost, with data usage heavily limited to specific functionalities, such as login integration.
The updated developer agreement introduces new clauses under restrictions related to reverse engineering and other prohibited uses: developers are expressly forbidden from using, or attempting to use (or allowing others to use), X’s API or content to fine-tune or train foundational or frontier models.
Developers who violate these terms may face suspension of their API access or even legal action from X. This protective measure aligns with X’s vested interest in safeguarding its data, particularly as its proprietary AI, Grok, relies heavily on the platform’s content for training and operational insights. Grok has unrestricted access to the entire corpus of X’s data for analysis and response generation.
Nonetheless, major tech companies appear to be exceptions—firms such as Google have reportedly entered into agreements with X, enabling real-time data access via the API. Whether this access extends to AI training purposes remains uncertain.
In parallel, to deter unauthorized data scraping, X has enforced stringent access restrictions. For instance, users not logged into an account can only view specific tweets from specific profiles. To access a full timeline or user homepage, login is now mandatory.
Once a user is logged in and begins data scraping, X’s risk control systems can swiftly detect such anomalous, high-volume behavior, making it easier for the platform to impose bans. However, these protective measures have also inadvertently hindered the user experience for many legitimate users.
