But X makes it clear that it’s up to the user to judge the AI’s accuracy. “This is an early version of Grok,” xAI says on its lend a hand page. As such, the chatbot could “possibly provide false information, incorrectly summarize, or omit some context,” xAI warns.
“We encourage you to independently verify any information you receive,” xAI adds. “Please do not share personal information or any confidential and sensitive information in conversations with Grok.”
Grok…
Another area of concern is the massive data collection — especially since you automatically consent to sharing your X data with Grok whether you apply the AI assistant or not.
Grok xAI Help The middle page describes how xAI “may use your X posts, as well as your user interactions, inputs, and outputs from Grok, for training and tuning purposes.”
Grok’s training strategy carries “significant privacy implications,” says Marijus Briedis, NordVPN’s chief technology officer. Beyond the “ability of an AI tool to access and analyze potentially private or sensitive information,” Briedis adds, there are additional concerns “given the AI’s ability to generate images and content with minimal moderation.”
While Grok-1 was trained on “publicly available data through Q3 2023” but was not “pre-trained on X data (including public X posts),” Grok-2 was explicitly trained on all “posts, interactions, inputs, and outputs” from X users, according to the company, with all of them automatically opting in, says Angus Allan, senior product manager at CreateFuture, an AI implementation consulting firm.
The EU’s General Data Protection Regulation (GDPR) is explicit about obtaining consent to apply personal data. In this case, xAI could “ignore that for Grok,” Allan says.
This resulted in EU regulators putting pressure on X to suspend training among EU users within days of Grok-2’s launch last month.
Failure to comply with user privacy laws can lead to regulatory scrutiny in other countries. While the United States does not have a similar system, The Federal Trade Commission has previously fined Twitter. for failing to respect users’ privacy preferences, Allan notes.
Resignation
One way to prevent your posts from being used for Grok training is to set your account to private. You can also apply Privacy Settings X to opt out of future model training.
To do this, select Privacy & Security > Data Sharing & Personalization > Grok. IN Data sharinguncheck “Allow Grok to use your posts, interactions, inputs, and results for training and tuning purposes.”
Even if you no longer apply X, it’s still worth logging in and opting out. X can apply all of your previous posts—including images—to train future models unless you specifically tell it not to, Allan warns.
It’s possible to delete your entire conversation history at once, xAI says. Deleted conversations are removed from systems within 30 days, unless the company needs to keep them for security or legal reasons.
No one knows how Grok will evolve, but judging by its performance so far, it’s worth keeping an eye on Musk’s AI assistant. To keep your data protected, be mindful of the content you share on X and stay up to date with any updates to its privacy policy or terms of service, Briedis says. “Engaging in these settings allows you to better control how your information is processed and potentially used by technologies like Grok.”
