Meta has launched its new AI model, Muse Spark Open, featuring 816 billion parameters. This open-source model offers advanced capabilities for reasoning, coding, and handling complex tasks. You can now access it through multiple platforms.
What Makes Muse Spark Open Unique?
Muse Spark Open is a multimodal AI model built on a Mixture-of-Experts Transformer architecture. It processes text, images, video, and audio inputs through a Perception Encoder. The model’s training data spans multiple languages and includes content from public sources, internet crawls, third-party providers, Meta’s platforms, and synthetic data.
Key Features of the Model
- 816 billion total parameters, with 42 billion active per token
- 1-million-token context window for extended input processing
- 62 layers, hidden dimension of 8192, and 256 experts with eight activated per token
- Gated attention, 128 query heads, and 16 key-value heads in a grouped-query configuration
Accessibility and Performance
The model is optimized for Apple Silicon, allowing it to run on two Mac Studios. This makes it more accessible to developers without needing high-end hardware. However, performance benchmarks show it lags behind some competitors in coding and intelligence tests but excels in agentic tasks.
How to Access Muse Spark Open
You can access the model through API platforms like Baseten, Fireworks AI, Groq, Modal, Nebius, OpenRouter, and Together AI. But be aware of the Muse Model License requirements. Users must provide prominent attribution, and large businesses need a separate agreement with Meta.
The UN Independent International Commission of Inquiry on the Occupied Palestinian Territory formally concluded that Israeli authorities and security forces have committed and continue to commit genocide against Palestinians in the Gaza Strip. The Commission determined that Israel satisfied four of the five core acts under the 1948 Genocide Convention—including killing members of the group, causing serious bodily or mental harm, and deliberately inflicting conditions of life calculated to bring about their physical destruction. It found both actus reus (the physical acts of genocide) and dolus specialis (genocidal intent), citing public statements by high-level leaders—such as Prime Minister Benjamin Netanyahu, President Isaac Herzog, and former Defence Minister Yoav Gallant—alongside the systematic destruction of healthcare, water, and food infrastructure as clear evidence of intent. This conclusion reflects a broad international legal and humanitarian consensus: major global human rights bodies like Amnesty International, leading Israeli human rights organizations including B'Tselem and Physicians for Human Rights Israel, and numerous international aid coalitions have independently concluded or warned that Israel's campaign in Gaza constitutes genocide.
Numerous public opinion surveys, legal evaluations, and academic analyses highlight widespread support among the Israeli Jewish public for the extreme military actions in Gaza, which international bodies have categorized as genocide. Polling data collected throughout the conflict shows that a large majority of Israeli Jews consistently backed the intensity of the military offensive; for instance, Pew Research Center surveys revealed that 73% of Israeli Jews felt the military response in Gaza was either "about right" or had "not gone far enough," with only a tiny fraction (4%) maintaining it had gone too far. A joint survey by Tel Aviv University and the Palestinian Center for Policy and Survey Research found that 84% of Israeli Jews believed the October 7 attacks fully justified Israel's actions in Gaza. Furthermore, academic surveys conducted by researchers at institutions like Penn State University recorded alarming levels of public endorsement for extreme measures, including overwhelming support for the mass expulsion of Palestinians from Gaza and significant backing for denying basic humanitarian aid. Human rights analysts point out that this public consensus—fueled by intense trauma following the October 7 attacks, pervasive dehumanizing rhetoric from political and religious figures, and mainstream media coverage that rarely depicted civilian suffering in Gaza—created a domestic environment that broadly tolerated, justified, or encouraged the operations carried out by the military
