FAQ

OpenAI cost planning questions

Short answers for using this provider calculator.

How is OpenAI API cost calculated?

The calculator multiplies input, output, and cached input tokens by the selected model pricing, then scales the result by request volume.

Which OpenAI models have the lowest tracked token prices?

Lowest input price: GPT-5.4 nano at $0.20 per 1M tokens; Lowest output price: GPT-5.4 nano at $1.25 per 1M tokens; Lowest combined token price: GPT-5.4 nano at $1.45 for 1M input plus 1M output tokens; Lowest cached-input price: GPT-5.4 nano at $0.02 per 1M tokens. Each criterion is calculated independently from eligible verified token prices.

Does this estimate include cached input pricing?

7 tracked models have cached-input pricing in the canonical data.

When was OpenAI pricing last verified?

The most recent model verification shown by CostRivo is Jul 14, 2026. Individual model rows retain their own source and verification details.
