After the IT company unveiled Muse Spark, the AI project meant to rival OpenAI and Google, Meta’s stock shot through the roof

The first large-scale language model created under the direction of Alexandr Wang, head of AI, was introduced by Meta on Wednesday under the name Muse Spark, formerly known as Avocado. As Meta aims to overtake AI behemoths like OpenAI, Google, and Anthropic, the launch increased the company’s stock price.

Meta’s website and app offer the AI model. The company claims it can perform the same tasks as its previous model, Llama 4 Maverick, with less computational power.

Muse Spark is Meta’s first AI model under Wang’s leadership, a billionaire tech entrepreneur whom Meta hired as head of AI after investing $14.3 billion in his company, Scale AI.

Following the announcement, Meta’s shares increased as much as 9% on Wednesday, recovering losses from late March.

Muse Spark’s release was delayed, ostensibly due to the AI model’s failure to surpass competing models created by Google, OpenAI, and Anthropic in performance testing.

According to a comparison table included in Meta’s statement, Muse Spark can either match or surpass competing AI models in a variety of performance tests. Meta intends to invest $135 billion in AI this year, which is almost twice as much as it did in 2025.
