Meta Platforms has released its new AI model, Muse Spark, after delaying the launch from March to May. The model scored 52 on the Intelligence Index, trailing leaders like Gemini 3.1 Pro and GPT-5.4, but excelling in health-related tasks and multimodal reasoning. The delay allowed Meta to narrow the competitive gap with rival models, and the market responded positively, sending the stock nearly 10% higher over five trading days.

Why it matters

The AI arms race among tech giants continues, with companies pouring billions into developing powerful AI models. Meta's decision to delay the launch of Muse Spark in order to deliver a more competitive product highlights the importance of patience and quality over speed in this fast-moving field. The performance of Muse Spark and its impact on Meta's stock price demonstrate the high stakes for investors as they watch these companies battle for AI supremacy.

The details

Muse Spark, Meta's first major AI model in over a year, was initially code-named 'Avocado' and was set to launch in March. However, internal tests showed the model fell short of rival performance levels, prompting Meta to delay the launch until May to allow the newly restructured AI team to rebuild the model from the ground up. The wait appears to have paid off, as Muse Spark now powers Meta's AI app and website, with plans for integration across WhatsApp, Instagram, Facebook, Messenger, and AI glasses.

  • In March, Meta Platforms delayed the launch of what was then code-named Avocado.
  • Muse Spark was released in May 2026.
