Meta's Muse Spark: Closed AI Challenges OpenAI & Google

Meta has launched Muse Spark, its first completely closed AI model, moving away from its usual open-source approach. This new AI is the first product from Meta Superintelligence Labs. Here's the thing: Muse Spark's internal workings are not public, and you need an invitation to use it. This is a big change from their Llama models. What's interesting is that Meta says future versions might become open source. This new AI can handle text, images, and voice. It even has a "Contemplating" mode that lets it think through problems like Gemini Deep Think and GPT Pro. Meta worked with over a thousand doctors to train Muse Spark, aiming to make it a personal health reasoning tool. The bottom line: This move signals Meta's intention to compete directly with leading AI models like GPT-5.4 and Gemini 3.1 Pro, potentially changing the landscape of AI development and access.
