Model Detail
Muse-Spark-Open-816B-A42B
—Muse-Spark-Open-816B-A42B is a multimodal model with 816B parameters released by meta-models. The model is registered under the image-text-to-text pipeline tag on Hugging Face, and supports text+image+file+audio+video->text inputs, distributed under a other license.
Muse-Spark-Open-816B-A42B is priced at $1.25/M input tokens and $4.25/M output tokens. Operationally the model offers a 1049K-token context window, which matters when sizing it for prompt-heavy or latency-sensitive workloads. Pricing in this range is the working middle of the API market — neither the cheapest nor the most expensive option per token, so cost-fit is usually a function of how much output you generate.
Muse-Spark-Open-816B-A42B ships with 816B parameters. Total weight footprint is approximately 822.0 GB, which is the relevant figure when planning local-inference VRAM. Access is gated on Hugging Face under the other license, which means a manual approval step before weights can be downloaded.
Muse-Spark-Open-816B-A42B is best fit for mixed text-and-image reasoning tasks such as document understanding, and long-context tasks such as full-codebase analysis or book-length summarization (1049K tokens). Treat this as a starting matrix rather than a benchmark verdict — the right deployment usually depends on the specific evaluation suite that mirrors your workload.
Muse Glimmer 30B: An On-Device Agentic Model
arXiv:2610.24628v2 Announce Type: replace-cross Abstract: We introduce Muse Glimmer, an open-source 30B parameter causal language model with perception encoder, purpose-built for autonomous agentic tasks on consumer hardware. Muse Glimmer integrates multi-step reasoning, reliable tool use and failur
Meta pauses Muse sharing after researchers find AI chats on the web
Meta says it paused a Muse feature that lets you share conversations with the AI assistant after researchers found the URLs publicly available on the web, as reported by Ars Technica. In a report published this week, researchers at the security firm Claroc say they found more than 6,800 Muse links t
Meta’s Muse hits 10M US downloads in 40 days, a milestone reached by only 11 other apps
New data also shows Muse is retaining users at higher rates than its AI rivals.
Meta and Apple team up to make Muse AI models run better on Macs
Meta announced the Muse Spark Open AI model today, claiming that it's the "most capable US open-weight model to date." But the company also says that it's the "the first model in its class" that can "run on your desktop using two Apple M5 Ultra Mac Studios with the latest MLX framework." Meta and Ap
Welcome Muse Spark Open: open-weight frontier multimodal mixture-of-experts model from Meta
Meta releases its first frontier model, Muse Wonder
Where Muse Spark aimed to be a lightweight model that could perform at low latency, the Wonder models are larger and said to be more capable, with higher benchmark scores and better results on complex tasks like coding.
