Original: I remember the exact moment I realized AI API pricing was a trap. I was building a document summarization tool. The math

A developer building a document summarization tool has described how GPT-4o-mini's low headline price of around $0.15 per million input tokens looked attractive in initial calculations, but the true cost at scale turned out far higher. The account has struck a chord with other builders who say per-token API pricing hides real-world expenses from usage growth, retries, and output tokens, prompting warnings to model total costs before committing to AI APIs.

Why now: Developers are increasingly confronting unexpectedly high costs when scaling AI-powered applications, making API pricing a hot topic.
