Meta's 816B Muse Spark Open Offers Full Agent Training Stack, But Chinese Models Lead

Meta released Muse Spark Open, an 816B parameter multimodal model for coding and long-horizon agents, accompanied by a complete post-training ecosystem including TorchTitan, SGLang, vLLM, Miles, and verl, with experimental results showing GRPO training improvements on math and geometry benchmarks, though Chinese models like Qwen, GLM, and Kimi already surpass it on coding benchmarks and have similar training infrastructure.
