Bluesky Promises Not to Use Your Content to Train Generative AI

With X and Meta using public posts to train its AI, Bluesky—which has seen a surge in sign-ups—says it has no intention of doing the same.

With X formally harnessing public posts to train its AI models, rival Bluesky is going in the opposite direction by rejecting the controversial business practice.

“We do not use any of your content to train generative AI, and have no intention of doing so,” Bluesky told users on Friday.

Bluesky made the statement on the same day X began enforcing new rules to let the company tap user posts to train AI models. X owner Elon Musk first talked about doing so over a year ago, which sparked some users, particularly artists, to bail from the social media platform. 

The main worry is that future AI models from X will plagiarize user content without any recourse or compensation for creators. Mark Zuckerberg's Meta, which runs X rival Threads, also uses public posts to train its AI programs

That prompted some artists and creators on Bluesky to ask about the company’s own stance on AI training. In response, the social media platform said it only uses AI to assist in content moderation and for its recommendation algorithms. “None of these are Gen AI systems trained on user content,” Bluesky added. 

The decision will likely strengthen Bluesky’s appeal, especially among artists and privacy-conscious users. On Thursday, Bluesky reported adding another 1 million users in a single day. The platform now has more than 17 million users, up from 9 million in September. 

X is facing backlash from some users over Musk’s support of President-elect Donald Trump. Still, X was estimated to have 251 million daily active users back in July. Meanwhile, Threads said it recently crossed 275 million monthly active users.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
