The 816B-parameter mixture-of-experts model activates 42B parameters per token, accepts text, images, audio and video, and has a one-million-token context window. Reference paths include Hugging Face endpoints, SGLang, vLLM, llama.cpp and oMLX. The custom license requires attribution and a separate agreement for model-as-a-service businesses above $20 million in annual gross revenue.</p><p>Recommendation: TRIAL</p><p>Sources: <a href="https://research.meta.ai/blog/introducing-muse-spark-1-3">research.meta.ai · introducing muse spark 1 3</a></p>
