Meta Muse Spark Open is trending on social media – A comparison with DeepSeek reveals why
Meta has officially launched Muse Spark Open as its take on an “open-weight” AI model. Meta, in fact, is describing it as the most capable US open-weight model released to date. Designed specifically for complex coding and autonomous agentic workflows, the model boasts of 816 billion parameters (with 42 billion active at any given time via a mixture-of-experts architecture) and a massive 1-million-token context window.
Similar to most other large-scale open-weight models, Muse Spark Open is available immediately for download on platforms such as Hugging Face, OpenRouter, and Groq, and is even capable of running locally across high-end hardware setups like dual Apple Mac Studio rigs equipped with M5 Ultra chips.
