On April 8, 2026 (local time), Meta rolled out its multimodal reasoning model, Muse Spark. This marks Meta's first official offering since the inception of the Meta Superintelligence Lab (MSL) in June 2025. Muse Spark is designed to excel in multimodal perception and reasoning, incorporating features such as tool utilization, visual chain-of-thought analysis, and multi-agent orchestration. Notably, it boasts computational efficiency more than 10 times that of its predecessor, Llama 4 Maverick.

In internal benchmark tests, Muse Spark showcased top-tier performance in areas like health Q&A and scientific chart analysis. For instance, it outperformed GPT-5.4 by over 2 percentage points on the HealthBench Hard test and surpassed Gemini 3.1 Pro on the CharXiv Reasoning test. Nevertheless, it still falls short of leading models in certain aspects, particularly programming capabilities.

Currently, Muse Spark is powering Meta's AI applications and websites, with plans to expand its deployment to platforms such as WhatsApp and Instagram. The launch has been met with enthusiasm on Wall Street. Morgan Stanley analyst Brian Nowak assigned Meta an 'Overweight' rating and set a price target of $775, hailing it as 'the first step in re-evaluating Meta.' Bank of America analyst Justin Post reaffirmed a 'Buy' rating and raised the price target to $885, highlighting the early-than-anticipated release. On the day of the announcement, Meta's stock surged by 6.5%, adding approximately $111 billion to its market capitalization, which now stands at $1.59 trillion.
