TLDR
Mark Zuckerberg stated that Muse Spark 1.2 is the next step toward larger frontier models. He described it as auditable by design, with every model call, tool run, and edit recorded in a local event log that allows recovery from crashes without re-prompting. Separate posts noted a 3-point gain on the Artificial Analysis Intelligence Index to 54, concentrated in agentic tasks such as GDPval-AA v2, Terminal-Bench 2.1, and Tau3-Bench Banking. One reply placed the model on the Pareto frontier at $0.40 per task.
