Artificial Analysis：GPT-6.1 Sol 的 Cost per Task 较 GPT-6 Sol 低约 30%

GPT-6.1 Sol has a ~30% lower Cost per Task than GPT-6 Sol, which was already ~half the cost of GPT-5.6 Sol

Cost per Task is a weighted average cost of completing tasks in the Artificial Analysis Intelligence Index.

GPT-6 Sol’s lower cost was driven by a 50% price cut, whereas GPT-6.1 Sol uses fewer turns (reducing its input token cost) and has a lower cache read price. At max effort, both GPT-6 Sol and GPT-6.1 Sol produce more output tokens than their predecessors, which slightly offsets the cost reductions.
