Our Commentary
Multi-model orchestration for code quality in Copilot? This is exactly where we expected AI coding assistants to go. The idea of reducing costs while improving quality is the holy grail. I'm curious about the practical implications for developers. Will it make code reviews obsolete? Or just shift the focus? We're seeing AI move beyond simple suggestions to more complex, orchestrated tasks. It's a bit unsettling how quickly these systems are evolving.
