Meta Launches Muse Ember AI Model for Agent Workflows; Shares Rise

Meta Platforms shares climbed 5.39% to $643.01 following the launch of Muse Ember, its smallest and most cost-efficient artificial intelligence model to date. Released by Meta's Superintelligence Lab, the lightweight model is engineered for agent execution and high-frequency automated tasks like tool calling and coding subtasks. Priced at 10 cents per million input tokens, Ember supports text, image, and audio inputs. It is the fourth model in Meta's Muse family, designed to work alongside frontier models such as Muse Wonder.
