Elon Musk praised X as a platform for product announcements, replying to Meta CEO Mark Zuckerberg's post about the release of Muse Spark 1.1, a coding model available through Meta Model API and in Meta AI. Musk stated, "X is a great platform for product announcements, especially if done by the CEO directly," and noted, "This post by Mark Zuckerberg already received over 12 million views for free!" The announcement garnered over 10 million views. Zuckerberg described Muse Spark 1.1 as the "strongest at agentic performance, tool use, and computer use," adding it "does well on long-running tasks with 1M token context window, can delegate execution to sub-agents running in parallel, and is trained to use computer interfaces on desktop, mobile, or browser." Meta Model API permits developers to build using Muse Spark for the first time, focusing on delivering strong agentic and multimodal models at considerably low cost. The updates were made in a series of posts on X on Thursday, with Musk's reply coming a few hours later.
