Firstly, this source is unreliable. A simple link to a social media post cannot be trusted to provide correct and unbiased information, not to mention the fact that since posting this claim, the post you are linking to has been deleted, further suggesting the claim is false.
Bluesky does currently use AI in its interface, though not in the way the claim is suggesting (meaning, differently from Twitter). According to the platform's official account, Bluesky does use AI internally, but instead of a generative chat bot or image creator, the AI is used as a tool to assist in content moderation to hide or otherwise flag inappropriate/harmful posts, as well as assisting create the algorithm for the optional "Discover" feed the platform offers.
Furthermore, the Bluesky account has publicly stated that it has no intention of introducing generative AI to the platform in this statement made on November 15th of last year: "A number of artists and creators have made their home on Bluesky, and we hear their concerns with other platforms training on their data. We do not use any of your content to train generative AI, and have no intention of doing so."
With this in mind, unless something major changes in the future, BlueSky does not and will not be utilizing large generative AI companies to create a platform more similar to that of Twitter.
