On Thursday, Meta Platforms Inc. (NASDAQ:META) CEO Mark Zuckerberg returned to X after nearly three years to unveil the company’s latest AI model.
Mark Zuckerberg Returns To X
Zuckerberg broke his long silence on X to introduce Muse Spark 1.1, Meta’s newest artificial intelligence model designed for agentic AI tasks.
In his post, Zuckerberg said Muse Spark 1.1 delivers improved coding, tool use, computer-use capabilities and multimodal reasoning.
Meta described the model as the first major release from its Meta Superintelligence Labs, calling it a significant upgrade over the original Muse Spark.
According to the company, the AI is built to coordinate multiple AI agents working in parallel, manage long-running tasks, retain context across extended sessions and determine when to automate workflows or interact directly with computer interfaces.
The release follows this week’s launch of Muse Image.
Elon Musk And X Executive React To Zuckerberg’s Return
Zuckerberg’s post quickly drew playful responses from rivals.
Nikita Bier, a product executive at Elon Musk’s X, replied, “Hello Mark, would you like me to enable Creator Monetization on your account,” joking about Zuckerberg’s years-long absence from the platform.
Musk also chimed in with a brief “Jinx,” likely a nod to the Wednesday announcement about xAI’s Grok 4.5 model, which also focuses on coding, research and complex work tasks.

Meanwhile, popular tech YouTuber Marques Brownlee, better known as MKBHD, highlighted a Meta AI feature rolling out on Instagram.

Brownlee also shared instructions for opting out by opening the Instagram profile page, tapping the three-line menu, navigating to “Sharing and reuse” and turning off the settings for both Posts and Reels.
