Zuckerberg would rather 'defect' to Threads than announce the new model on X. Meta CEO Zuckerberg made the rare choice to post about the new model Muse Spark 1.1 on X, marking his first post on the platform in over three years. Some netizens joked that if this post were made on Threads, no one would even understand what it’s about . After all, X is where the world’s most tech-savvy crowd gathers. Turns out, the move paid off: the tweet has already surpassed 10 million views, with comments, retweets, and likes far ahead of the curve. According to benchmark data released by Meta, Muse Spark 1.1 outperformed Anthropic Opus 4.8 and OpenAI GPT 5.5 in tests like tool invocation (MCP Atlas) and professional task handling (JobBench). Zuckerberg called it a 'highly cost-effective intelligent agent and programming model.' For this highly anticipated model, he was willing to 'defect' from his own social platform to make the announcement on X. This time, he definitely got the attention he was looking for.
