Muse Spark 1.2 以每任务0.40美元登顶帕累托前沿

Muse Spark 1.2 puts Meta on Artificial Analysis's Pareto frontier at $0.40 per task.

i.e. on that frontier, no model in the comparison is simultaneously cheaper per task and higher on the Intelligence Index.

Muse Spark 1.2 also reaches roughly Claude Opus 4.8-level intelligence at about one-fifth of that model's $2.03 task cost.

It scores 6 Index points below Claude Opus 5 while costing roughly one-sixth as much.

The metric goes beyond just the list price because Artificial Analysis weights the input, cache, reasoning, and answer tokens actually consumed across its nine Index evaluations.

This is so significant because for long-running agents, small cost differences compound across model calls, reasoning tokens, tool steps, and retries.
