Our Commentary ​

Meta's entry into the coding agent space with Muse Code and Spark 1.2 is a big deal. The focus on "long-sequence agentic tool calling" is definitely where the industry is heading. But that pricing model? A massive discount for letting them use your data? That's a bold move. It makes me wonder about the long-term implications for privacy and competitive advantage. I'm genuinely torn on how to feel about that.
