Meta releases Muse Spark Open, a new ‘open-weight’ AI model
Meta says Muse excels at ‘multi-step reasoning’ and ‘complex software engineering’ as it races to catch up to Chinese rivals Meta on Thursday launched a new open-weight AI model which it claims rivals, and in some cases outperforms, similar products from leading Chinese developers. Muse Spark Open “is the most capable US open-weight model to date,” Meta’s chief of AI Alexandr Wang wrote on X.…
Meta launched Muse Spark Open, a new open-weight AI model, on Thursday, vying to compete with Chinese rivals. The model is capable of multi-step reasoning and complex software engineering tasks, according to Meta. Unlike closed models from companies like Anthropic and OpenAI, developers can modify the parameters of Muse Spark Open, which consists of weights and biases.
Chinese developers have been leading the open-weight market in AI models recently, with models like Alibaba's Qwen and Moonshot AI's Kimi K3 being recognized as global frontrunners. However, Meta asserts that its new open model now holds a similar level of competition. "Built for coding and agentic work," Muse Spark Open "excel[s] at long-horizon tasks, complex software engineering, and multi-step reasoning," Meta stated in a blog post.
The model has also been optimized to run on Apple's advanced M5 Ultra chips, marking an unusual partnership between the two companies. Running Muse Spark Open requires substantial computing power, but users can create a "supercomputer" on their desktop using two Mac Studios with M5 Ultra chips, Meta explained. This launch follows Meta's recent announcement of a new closed model that it claims rivals the most advanced versions of ChatGPT and Claude.
Meta's AI strategy has shifted from an initial focus on open models to now competing with OpenAI and Anthropic.
