Woofun AI reports that Coinbase has decreased artificial intelligence expenditures by approximately 50% through the adoption of open-source models like GLM 5.2 and Kimi 2.7 as its default infrastructure. CEO Brian Armstrong confirmed that the firm no longer employs usage limits or spending alerts for cost control, instead reserving advanced proprietary models for specific high-demand scenarios. The company further optimizes inference costs via intelligent model routing, enhanced cache hit rates, and streamlined context management, coinciding with an exponential rise in token utilization.
