Our Commentary ​

It's always good to see the underlying tech explained, especially for something as widely used as Copilot. I wonder how much of this internal efficiency translates directly to a better developer experience. Token efficiency is crucial for cost, but what about the quality and relevance of the suggestions? That's the real metric for me.
