Meta Launches Muse Spark, Its Most Powerful AI Model Built by Alexandr Wang's Superintelligence Labs

Meta is back in the AI race. The company released Muse Spark, marking its "first step" toward an "overhaul of its AI efforts" and the inaugural model from Meta Superintelligence Labs, created after CEO Mark Zuckerberg grew frustrated with Llama's lag behind OpenAI's ChatGPT and Anthropic's Claude. The model, code-named Avocado, was built over nine months by a team led by Alexandr Wang. According to benchmark tests Meta published, Muse Spark is competitive with leading AI models from OpenAI, Anthropic, and Google across many tasks and appears to put Meta back in the race after Llama 4 was widely panned as a dud. The model uses a fast mode for casual queries, several reasoning modes, and a "shopping mode" that combines large language models with data on user interests and behavior. Meta's AI-related capital expenditures in 2026 are projected between $115 billion and $135 billion, nearly twice last year's figure. The model raises privacy concerns, as users must log in with an existing Facebook or Instagram account to access it. Muse Spark is currently only available in the United States.
