Copilot turns model choice into an operating control
Auto model selection is no longer just automatic. It now carries a budget and quality preference.
GitHub Copilot auto model selection now offers three tiers: efficiency, balance, and intelligence. That matters because agentic coding work is becoming less about picking one model forever and more about routing each task to the right cost, quality, and speed profile. For daily shipping, this is a useful shift rather than a grand announcement. Small fixes, documentation cleanup, and first-pass scaffolding can default toward efficiency, while high-risk architecture or release work can justify intelligence. The practical move is to stop treating Copilot as one undifferentiated assistant and start logging which tier handled which class of task, then compare review burden and output quality after a week.
