Meta releases Muse Spark Open with open weights on Hugging Face
Meta is launching Muse Spark Open via Hugging Face. The model is based on a mixture-of-experts architecture and is being made available with open weights for multimodal applications.
What happened?
Meta has launched the Muse Spark Open model, a multimodal mixture-of-experts (MoE) model with open weights. The model is being made available through the Hugging Face platform for research and application development. The weights allow for local execution and further development within multimodal inference.
Key facts

|---|---|
| Arkitektur | Multimodal Mixture-of-Experts (MoE) |
| Distribution | Öppna vikter via Hugging Face |
Why it matters
Open MoE architectures allow developers to run resource-intensive multimodal models with lower computational costs per inference compared to dense models. The release broadens options for teams that require full control over their weights and infrastructure.
Who is affected?
The model is aimed at AI researchers, software engineers, and companies building multimodal systems. It is particularly relevant for teams seeking open-weight alternatives to proprietary APIs.
Impact on the EU
Because the weights are published openly via Hugging Face, developers within the EU can download and run the model locally. This means that organisations can tailor their implementation to meet GDPR and the requirements of the EU AI Act without relying on external cloud servers.
What else you should know
The release is conducted via Hugging Face, but details regarding training data and potential limitations in the licence terms should be carefully reviewed by developers before commercial deployment.
