Scale Agentic Coding Workflows with Meta's Muse Spark Open on NVIDIA GB300 NVL72

Meta has launched Muse Spark Open, an 816 billion parameter mixture-of-experts AI model optimized for agentic coding workflows, trained on NVIDIA's GB300 NVL72 Blackwell Ultra. It supports up to a 1 million token context window enabling complex project comprehension, includes multimodal perception across text, image, audio, and video, and runs efficiently with NVFP4 checkpoints to deliver high throughput and low cost per token.
