Persistent, Embedded, and Multimodal Agents Intensify Competition

Meta’s Muse Ember is positioned as a low-cost model for repetitive agent workloads, but its performance and cost claims—including a social post’s $0.04-per-website figure—lack independent validation. Amazon’s Alexa for Shopping rollout underscores platform control of agent-mediated commerce, while Anthropic’s reported Fable 5.2 and Mythos 5.2 launch adds model competition. Meta’s Muse Spaces and other adjacent agent products remain relevant context, but company and promotional claims require scrutiny.
