Mark Zuckerberg announced that Meta's Watermelon model and open weights version of Muse Spark are coming soon, following the rollout of Muse Spark 1.3 with significant improvements in coding and agentic capabilities.
Meta released Muse Spark 1.3 today, marking what Zuckerberg described as the company's "biggest jump so far" on coding and agentic work. The model is now available through Muse Code and Meta's API.
Zuckerberg highlighted the frontier-level performance of Muse Spark 1.3, characterizing the cost as "almost too cheap to meter." The update reflects Meta's continued investment in AI development, particularly in areas designed to assist with code generation and autonomous task execution.
The announcement hints at two forthcoming releases. The Watermelon model remains undetailed, with no specifications or timeline provided beyond the vague "coming soon" designation. Similarly, Zuckerberg indicated that open weights versions of Muse Spark will be released, though no date was specified.
Open weights releases are significant in the AI community, as they allow researchers and developers to access model architecture and weights for local deployment and modification. Meta has previously released open weights models, positioning the company as a contributor to accessible AI development.
The roadmap suggests Meta's focus on making advanced AI capabilities available to developers at scale. Muse Spark's emphasis on coding and agentic work aligns with broader industry trends around AI-assisted software development and autonomous agents.
No additional details about Watermelon's purpose or capabilities were disclosed. The timing of these releases remains unclear, with Zuckerberg offering only that they would arrive "soon."
