ant:reasoning-premiumThe deepest reasoning tier — thinking-capable models scoring 85 or above.
ant:reasoning-premium is the strictest pool available: models must support extended thinking and score at least 85, and the router weights quality at the maximum while accepting the highest latency and cost. Use it for the problems where nothing else has worked.
