Meta cuts the cost of frontier AI tasks
Meta built Muse Spark 1.3 for long agent and coding jobs. Artificial Analysis gave it a frontier-tier score and measured lower task costs than nearby rivals.

The evidence
What the reporting establishes
What happened
Meta released Muse Spark 1.3 on Wednesday in Muse Code and the Meta Model API. Meta says the model handles longer agent workflows and follows complex instructions more reliably. Meta engineers also measured about 20 percent fewer tool calls and 25 percent fewer tokens than Muse Spark 1.2. Artificial Analysis gave the available xhigh version a 61 on its Intelligence Index. That put it four points above Muse Spark 1.2 and tied it with several frontier systems. At Meta's unchanged API price, Artificial Analysis measured a $0.55 cost per index task. No other model scoring 59 or higher cost less. The limited-preview max version scored 62, one point higher, but Meta has not published its price.
Why it matters
Meta did not beat the benchmark. It reached the frontier tier at a lower measured cost. Agent products rack up cost when a model reads context, works through a task, calls a tool, and checks its work. A lower bill lets more jobs run in the background. It also makes rivals defend price, not only capability.
The caveat
Meta made the usability and safety claims. Artificial Analysis measured benchmark performance and task cost independently. A benchmark still does not prove that a model will hold up inside a specific business workflow.
What to watch
Watch whether the max version keeps its score after a wider release. Watch what Meta charges for it, and whether Meta ships the promised open-weights release. Real agent completion rates matter too. Meta reports fewer tool calls and tokens. Product teams still need to test that efficiency on their own work.
