Wu learned that Coinbase CEO Brian Armstrong stated that the company has nearly halved its enterprise AI spending by optimizing infrastructure, while AI token usage continues to grow exponentially. Key cost reduction measures include: adopting open-source models such as GLM 5.2 and Kimi 2.7 as the default options for the internal LLM gateway, using intelligent routing to match tasks with the most cost-effective models, and significantly increasing the cache hit rate of tools like LibreChat from 5% to 60%. Armstrong emphasized that the goal of managing AI costs is not to limit usage, but to make exponential growth sustainable by reducing waste.
