我意外收到了 400 美元的 AI API 账单 - 所以我构建了 CostPulse

Last month, the author discovered an unexpected $400 bill from OpenAI while running experiments and building prototypes. Although each API call seemed minor, the costs accumulated quickly. The author identified several issues in current API usage, including lack of real-time visibility into spending, difficulty in forecasting expenses, the delayed nature of billing, and challenges in attributing costs to specific projects. To address these problems, the author developed CostPulse.ai, a tool for AI developers that provides real-time API cost forecasting. Key features include connecting OpenAI/Anthropic accounts, viewing costs as they occur, receiving budget alerts, and forecasting end-of-month expenses.
