Meta’s Muse Spark Open lands in Amazon SageMaker JumpStart
AWS has added Meta’s Muse Spark Open to SageMaker JumpStart in BF16 and NVFP4 variants. The open-weight coding model has 816 billion total parameters, activates 42 billion per token and supports a one-million-token context across text and multimodal inputs. Customers can deploy controlled endpoints, but multi-GPU cost, licensing and tool permissions require careful evaluation.
