It is specifically built for agents and coding, being able to write, debug and refactor large codebases and add features on the fly.
The agentic capabilities are very competitive, Meta says. It can work with little human intervention and sometimes scores better than Fable on these tasks.
On computer use, Meta claims it understands workflows and can write scripts when it’s faster and work directly when it’s simpler.
Perhaps the biggest selling point is the cost, and just like Grok 4.5 yesterday, competition on price and speed is picking up. Muse Spark 1.1 is only $1.25 per million input tokens and $4.25 per million out, and is, as Zuckerberg puts it, at a very low cost.
The new Spark is available in Thinking mode on Meta AI through meta.ai and the app, while U.S. developers can access it in public preview through the new Meta Model API, where there is a waitlist. There is no word on when it is coming to Europe.
