Meta releases "America's Strongest Open Source Model"
Core Viewpoint
Meta released Muse Spark Open: a mixed expert model with a total of 816 billion parameters and 42 billion active parameters, open weights, native support for multimodal, and a context window of up to 1 million tokens, known as the most powerful open-source weight model in the United States to date.

The licensing agreements have also been subdivided. Glimmer uses the completely open Apache 2.0, while Spark Open uses a custom Muse Model License------most developers can use it for free, but if your company provides model-as-a-service and has an annual revenue exceeding 20 million dollars, you need to sign a separate agreement with Meta.
On-premises deployment, research, and non-model service commercial applications are not restricted. This design is very precise------it's fine for internal use within the company, and it's also fine to use it to create your own products, but if you want to sell it directly as an API, then revenue sharing must be negotiated.
