Meta 发布开源权重模型 Muse Spark Open，816B 参数、1M 上下文

Meta released Muse Spark Open, an open-weight model with 816B total parameters, 42B active parameters and a 1M-token context window. The weights are available on Hugging Face under the Muse Model License.

Why it matters: Meta ships auto-tunable cross-hardware kernels and post-training support with the model, cutting the cost of building and maintaining custom kernels.
