Meta's Muse Spark 1.3 undercuts rivals with $0.55 tasks

meta has released muse spark 1.3 through muse code and the meta model api. the xhigh tier is available now, while the max tier runs as a limited preview. on the intelligence index, max scores 62 points and xhigh 61, up from 57 in august and 53 in july. the model improves most on agentic tasks, such as τ³-banking, where max hits 52 percent, and terminal-bench 2.1, where xhigh climbs to 85 percent. however, it still trails top performers like claude fable 5.1 across most benchmarks. the model is priced at $0.55 per task, making it the cheapest in its performance class, with an open-weights version planned.
