**[Meta Releases Muse Spark 1.3 Model to Advance Personal AI Agent Development]** Gold Finance reported on September 3 that Meta released the Muse Spark 1.3 model update on Wednesday, stating that this version has significantly improved performance in coding and agentic tasks. Meta AI head Alexandr Wang said the new model is "on par with cutting-edge models" and will pave the way for future personal AI agent products, helping users achieve AI assistants capable of working on their behalf around the clock. The price of Muse Spark 1.3 remains consistent with the previous version, and Wang described this pricing strategy as "aggressive." Meta also noted that its "contributor tier" option has been well-received by developers. This program significantly reduces coding product costs by allowing Meta to use developers' work to improve the model, with a "meaningful double-digit percentage" of developers opting into the program. Wang stated that as model capabilities improve, safety concerns have become a key focus within Meta, and the company is increasing investments in safety and alignment. Muse Spark 1.3 will be available the same day on Muse Code and Meta API, while the highest inference version will be launched after additional safety testing is completed.
