Meta Announces Muse Spark AI Model to Replace Llama 4 on Most Smart Glasses

Meta has announced Muse Spark, the first AI model from its Superintelligence Labs, which will replace Llama 4 as the primary engine for Meta AI on most Ray-Ban and Oakley smart glasses. Unlike the open-source Llama series, Muse Spark is currently proprietary, though Meta hopes to open-source future versions. The company states that this small, fast model matches the performance of Llama 4 Maverick while using 10x less compute, enabling instant responses crucial for real-world queries. However, Meta Ray-Ban Display glasses will continue to use a custom version of Llama 4 for now due to the complexity of generating visual responses. This update aims to narrow the gap with leading AI systems like Gemini and GPT, supporting Meta’s long-term goal of always-on contextual AI.
