Muse Spark 1.2 places Meta on the Cost per Task Pareto frontier, scoring 6 points below Claude Opus 5 at ~1/6th of the cost At Meta's $1.25/$4.25 per 1M token pricing, Muse Spark 1.2 (xhigh) sits on the Pareto frontier of Intelligence Index vs Cost per Task. It delivers comparable intelligence to Claude Opus 4.8 (max, $2.03) at a fifth of the cost per task, and undercuts GPT-5.6 Sol (high, $0.55), GPT-5.6 Terra (max, $0.61), and Kimi K3 (max, $0.87). The nearest cheaper options are Grok 4.5 (high, $0.36) and GPT-5.6 Sol (medium, $0.37), and they all sit below it on the Index. The step up from Muse Spark 1.1 ($0.29 per task) comes at unchanged per-token pricing, with the increase driven by heavier token usage on agentic tasks.
