Meta has launched a new proprietary AI model called Muse Spark, which is the company's first since the formation of Superintelligence Labs. The launch of Muse Spark has raised questions about the future of Meta's open-source Llama model, with some outlets suggesting it may be abandoned in favor of the proprietary technology. Muse Spark is seen as a competitor to rival AI models from other companies, including OpenAI and Google.
