Meta releases Muse Spark Open, an open-weight frontier multimodal mixture-of-experts model

Meta has released Muse Spark Open, a frontier-class multimodal model using a mixture-of-experts architecture, available as open weights via Hugging Face. This continues Meta's strategy of releasing powerful open-weight models to compete with closed offerings from OpenAI and Google. The MoE architecture and multimodal capabilities suggest this is a significant capability release, though the absence of content body limits detailed analysis.
