Ramp AI 指数显示：企业 AI 支出减少，使用量增加
Businesses are using more AI and paying less for it, Ramp AI Index shows
Ramp AI 指数显示，美国企业 AI 支出减少，主要得益于顶级模型价格下调和标准版、轻量版模型的性价比提升。自 7 月支出达到峰值后，使用量增长了约 50%，9 月底达到历史最高水平。开源模型在企业支出中占比不到 5%。Anthropic 和 OpenAI 分别占据了 51% 和 44.5% 的 token 支出。
US companies are spending less on AI, according to the latest Ramp AI Index from Ramp economist Ara Kharazian. He points to price cuts on top models and to cheaper, more efficient standard and lite models. Kharazian says the drop comes almost entirely from competition between OpenAI and Anthropic. Usage has climbed about 50 percent since spending peaked in July and hit a record high at the end of September.
Open-source models still make up less than five percent of business spending, Kharazian says. In the last week of September covered by the data, Anthropic took 51 percent of token spending and OpenAI took 44.5 percent.
The Ramp AI Index tracks transaction data from more than 70,000 US companies, and its token data comes from a subsample. According to Kharazian, the analysis only covers API spending and skews toward large AI customers. This isn't the first decline, but it has lasted unusually long. Spending peaked in July.
