Zuckerberg Returns to X, Launches Meta Muse Spark 1.1 AI

Meta CEO Mark Zuckerberg has returned to X after more than three years to announce Muse Spark 1.1, the company's newest artificial intelligence model. This AI model is built for agentic computing, coding, and tool use. What's interesting is that Muse Spark 1.1 is available through the Meta Model API and Meta AI at a very low price. Zuckerberg states it's designed to handle long tasks using a 1 million-token context window and supports parallel execution. The model can also operate computer interfaces across desktop, mobile, and web browsers for complex workflows. Meta claims Muse Spark 1.1 achieved high scores on various benchmarks, outperforming rival models in scaled tool use, professional tool use, and other evaluations. In coding, it scored 80.0 on Terminal-Bench 2.1. This move signals Meta's push to make advanced AI more accessible.
