https://unitedstatesofamericasuperintelligence.com/open/meta-muse/ Dated, sourced news items in the USASI catalog that mention Muse (Meta). Independent project. Not a United States government website. en-us Fri, 16 Oct 2026 12:00:00 GMT https://unitedstatesofamericasuperintelligence.com/news/meta-releases-muse-spark-open-open-weight-model/ https://unitedstatesofamericasuperintelligence.com/news/meta-releases-muse-spark-open-open-weight-model/ Fri, 16 Oct 2026 12:00:00 GMT release On October 15, 2026 Meta released Muse Spark Open, which its developer blog describes as the open-weight version of Muse Spark, trained for long-horizon agentic work such as coding and customer service agents. The model card lists 816B total and 42B active parameters, a context window of 1M tokens, text, image, video, and audio input, and text output; BF16 and NVFP4 checkpoints are on Hugging Face, and downloading them requires accepting the license conditions and submitting an access form. The weights are released under the Muse Model License, which requires a visible "Built with Muse Spark Open" attribution, incorporates a Usage Policy, and requires some large API providers to sign a separate agreement with Meta; the license does not describe itself as open source. USASI has not tested this model. https://unitedstatesofamericasuperintelligence.com/news/meta-releases-muse-wonder-and-muse-wonder-full/ https://unitedstatesofamericasuperintelligence.com/news/meta-releases-muse-wonder-and-muse-wonder-full/ Tue, 13 Oct 2026 12:00:00 GMT release On October 12, 2026 Meta announced two new models in its Muse family, Muse Wonder and Muse Wonder Full, which it says were built on the groundwork laid with Muse Spark. According to the announcement, Muse Wonder is available that day for developers and builders through the Meta Model API and Muse Code, and Muse Wonder Full is available to Muse Code subscribers. Meta says Muse Wonder will soon power experiences in Muse, rolling out first to subscribers. The announcement does not name a license or say that model weights are released, and USASI has not tested either model. https://unitedstatesofamericasuperintelligence.com/news/meta-releases-metaencoder-30b/ https://unitedstatesofamericasuperintelligence.com/news/meta-releases-metaencoder-30b/ Tue, 13 Oct 2026 12:00:00 GMT release Meta has published MetaEncoder-30B on Hugging Face as facebook/meta-encoder. The model card describes it as a multimodal bi-encoder, a "Multimodal System One Encoder", in which both the task and each candidate are written in natural language, with text, images, and video usable on either side. The card says it was built by contrastively fine-tuning Muse-Glimmer-30B and is released under Apache 2.0, inherited from the base model, with use also subject to the base model's Usage Policy; the files can be downloaded only after accepting access conditions on Hugging Face. The accompanying paper was submitted to arXiv on October 8, 2026; the model card does not give a release date. USASI has not tested MetaEncoder-30B. https://unitedstatesofamericasuperintelligence.com/news/meta-releases-muse-glimmer-open-weights/ https://unitedstatesofamericasuperintelligence.com/news/meta-releases-muse-glimmer-open-weights/ Tue, 29 Sep 2026 12:00:00 GMT release In August 2026 Meta Superintelligence Labs published Muse Glimmer, a model of about 30 billion parameters that takes text and images as input and was distilled from Muse Spark. Its weights can be downloaded from Hugging Face without an access request under the Apache 2.0 license, and the repository also includes a separate Muse Glimmer Usage Policy that lists prohibited uses. Muse Glimmer has its own release record under the Muse family. https://unitedstatesofamericasuperintelligence.com/news/meta-releases-muse-spark-1-1-and-meta-model-api/ https://unitedstatesofamericasuperintelligence.com/news/meta-releases-muse-spark-1-1-and-meta-model-api/ Tue, 13 Oct 2026 12:00:00 GMT release On July 9, 2026 Meta Superintelligence Labs introduced Muse Spark 1.1, which the announcement describes as a multimodal reasoning model built for agentic tasks and an upgrade over Muse Spark. Meta says the model is available in "Thinking" mode in the Meta AI app and on meta.ai, and that developers can reach it through the Meta Model API, which the post introduces as a public preview. The post lists a 1-million-token context window, computer use across multiple applications, and the ability to work as a main agent that delegates to parallel subagents. It does not say that the weights are released or give license terms. USASI has not tested Muse Spark 1.1. https://unitedstatesofamericasuperintelligence.com/news/meta-launches-muse-image-and-previews-muse-video/ https://unitedstatesofamericasuperintelligence.com/news/meta-launches-muse-image-and-previews-muse-video/ Tue, 13 Oct 2026 12:00:00 GMT release On July 7, 2026 Meta Superintelligence Labs launched Muse Image, an image generation model that can edit images, compose from multiple references, and use tools, and previewed Muse Video, which Meta says is built on the same pretraining base as Muse Image and supports native audio. Meta describes them as the first media generation models developed by Meta Superintelligence Labs. Muse Image is available in the Meta AI app and on meta.ai, in Instagram Stories in the U.S., and in WhatsApp in a limited set of countries, while Muse Video is described as coming soon, without a date. Meta says Muse Image outputs in the Meta AI app and on meta.ai include Content Seal, an invisible watermark; the post does not mention an API, open weights, or a license. USASI has not tested either model.
