Meta Muse Spark
Meta debuted Muse Spark on April 8, 2026, the first frontier model from Meta Superintelligence Labs and a 'ground-up overhaul' of its AI effort.
Why It Mattered
Muse Spark was Meta's first major model since reorganizing its AI division under Alexandr Wang's Superintelligence Labs, marking the company's shift away from the open-source Llama lineage toward a tightly controlled frontier program. A natively multimodal reasoning model with tool use, visual chain of thought, multi-agent orchestration, and a 1-million-token context, it launched via private API preview before powering Meta AI across WhatsApp, Instagram, Facebook, Messenger, and Meta's smart glasses; the upgraded Muse Spark 1.1 followed in July with a developer API.
