Muse Spark 1.1
READER SUMMARYMeta's broadly deployed multimodal reasoning model for long-horizon agentic work, multi-agent orchestration, computer use, coding, and external tool operation.
Why this model scores 80.9
Muse Spark 1.1 combines frontier coding and multimodal reasoning with million-token context management, multi-agent delegation, external tools, and computer use. Consumer availability and a public-preview API create broad reach. Meta reports frontier-risk, jailbreak, and prompt-injection testing within its scaling framework, which lowers but does not remove residual misuse and control difficulty.
News tied to Muse Spark 1.1
The model score of 80.9 rates this model's risk profile. The overall Doom Index of 100.0 measures the accumulated evidence trajectory. These values answer different questions.
Each article's signed Doom Index movement is divided equally among the exact models named on that article. This prevents multi-model evidence from being counted in full on several model pages. The model's risk score itself never changes the overall index.
