Lon Lundgren measured it five different ways after the model moved permanently into subscription plans. By August 22-23, median per-turn thinking sat about 41% below the July reference and median per-invocation thinking had dropped to zero, even at xhigh and max.

Vercel published its September AI Gateway Production Index on September 17, covering August traffic, and the headline reverses a story a lot of people have been telling. Open-weight models crossed a majority of token volume for the first time, at 56%. In December 2025 that fig...
