As of October 27, the Token Expenditure Price Index was $0.94 per million tokens, down 1.9% from seven calendar days prior. Compared to the peak of $2.065 per million tokens recorded on May 28, the index has cumulatively fallen by 54.48%, a drop of over 50% from its peak. The index remains at a low level, reflecting a significant decline in the unit token price of AI model inference services from its peak. Price competition in AI services and changes in inference costs still warrant attention.
