Mark Zuckerberg returns to Twitter after three years, gets message & tip from Elon Musk

Meta CEO Mark Zuckerberg returned to X (formerly Twitter) after nearly three years to announce the public release of Meta's new AI model, Muse Spark 1.1. His posts drew a response from X owner Elon Musk, who said the platform offers companies a way to reach millions of users directly without relying on traditional press releases. Announcing the launch, Zuckerberg wrote, "Today we're releasing Muse Spark 1.1 -- a strong agentic and coding model at a very low price. It's available through our new Meta Model API and in Meta AI."Replying to the announcement, Musk wrote, "X is a great platform for product announcements, especially if done by the CEO directly. Way more interesting to the public than generic press releases.
