How to Track OpenAI API Costs (When the Dashboard Stops Being Enough)
AICosts.ai
OpenAI's usage page shows spend by day and model but not by feature, customer, or anomaly. The three-layer tracking setup that catches cost spikes before the invoice does.

The OpenAI dashboard tells you what you spent. It doesn't tell you which product feature spent it, which customer drove it, or that a retry loop quietly tripled your embeddings bill on Tuesday. If you're running anything real on the API, "check the usage page" stops scaling almost immediately.
What the native dashboard gives you
OpenAI's usage page shows spend by day and by model, with per-key breakdowns if you discipline yourself to one API key per surface. That's genuinely useful for a single-project solo developer, and you should exhaust it before adding tooling.
- Where it ends: no per-feature or per-customer attribution, no alerts before the bill lands, no view across your other providers.
- The failure mode: you discover the anomaly in the invoice, weeks after the code that caused it shipped.
The three layers of real cost tracking
1. Tag at the call site. Every API call should carry metadata: feature, environment, customer tier. Log tokens in and out usage objects come back on every response; store them.
2. Price it daily, not monthly. Multiply logged tokens by current model pricing daily and write it somewhere queryable. Anomalies caught at $40 stay anecdotes; caught at $4,000 they become postmortems.
3. Budget per model and per feature. A hard number with an alert beats a dashboard you promise to check. Set thresholds where they hurt but don't page you for noise.
Where AICosts.ai fits
AICosts.ai ingests usage across OpenAI and 50+ other AI providers into one dashboard unified spend, per-model budgets, CSV/JSON export, and billing-file ingestion when API-level data isn't enough. If your AI spend lives on more than one invoice, that single pane is the point.
