Lets Investigate The Hype Around Facebook’s Big Comeback With Muse Spark 1.1, Fact or Fiction

Meta released Muse Spark 1.1 into public preview on July 9, offering a multimodal model with competitive pricing of $1.25 per million input tokens and $4.25 per million output tokens, along with 118.1 output tokens per second and a 1M-token context window. The model is positioned as a cost-effective worker for bounded tasks like screenshot triage and long-document extraction, though the author cautions against calling it a proven long-horizon agent.

Member-only story Lets Investigate The Hype Around Facebook’s Big Comeback With Muse Spark 1.1, Fact or Fiction Meta put Muse Spark 1.1 into public preview on July 9. The part I care about is not the usual claim that a new model can plan, code and use tools. It is the economics of giving a multimodal worker a real job inside an agent loop: $1.25 per million input tokens, $4.25 per million output tokens, 118.1 output tokens per second, and a 1M-token context window, according to Artificial Analysis. That combination makes the model worth routing into bounded work now. Screenshot triage, browser-and-tool tasks, scoped bug fixes, long-document extraction and repeatable verifier loops all become cheaper to run. Meta is calling the model a step toward personal superintelligence. I would keep the claim smaller: Muse Spark 1.1 looks like a serious worker model before it looks like a proven long-horizon main agent.
