Meta announced on Wednesday the release of Muse Spark 1.3, an update to its AI model that significantly improves performance in coding and agentic tasks. According to Alexandr Wang, Meta's AI head, the new model is "competitive with frontier models" and paves the way for future personal AI agents that can work on behalf of users around the clock. The pricing remains unchanged from the previous version, which Wang described as an "aggressive" strategy. Meta also highlighted the popularity of its "contributor tier" option, which allows the company to use developers' work to improve the model, thereby reducing coding product costs. A "meaningful double-digit percentage" of developers have opted in. Wang noted that safety has become a key internal issue as model capabilities improve, and Meta is increasing investments in safety and alignment. Muse Spark 1.3 will be available on Muse Code and Meta API on the same day, with the highest reasoning version to follow after additional safety testing. This update reflects Meta's ongoing commitment to advancing AI capabilities while maintaining a developer-friendly ecosystem and prioritizing safety as the technology evolves.
