Meta announced Muse Spark, its first major AI model under Meta Intelligence Labs, representing a strategic shift from its open-source Llama approach to closed-source distribution.

Third-party validators and Meta's self-reported benchmarks place Muse Spark in the top 5 models tested, signaling aggressive competitive repositioning against OpenAI, Anthropic, Google, and xAI.
