Abstract
We’re excited to release Muse Spark 1.3, which delivers improved performance across agentic and coding tasks. Drawing on what we learned from months of broad adoption of Muse Code and Meta Model API, we’ve also made this model easier to use in real-world settings. Smarter and more practically useful, Muse Spark 1.3 advances our work toward personal superintelligence.
