About OpenAI
OpenAI API models for chat, reasoning, coding, and multimodal work. OpenAI sits in CostUse’s catalog of usage-billed APIs. Instead of a thin brand blurb, this page assembles what matters for budgeting: what the company bills for usage, in which unit, at which list rate, and on which date the figure was checked against the public source.
There are 9 published calculators for OpenAI. List unit prices run from $0.000015 to $0.3, with a median of $0.006. Billing units represented here: audio minute, character, generated video second, tool call, file search tool call. The most recent price check in this group is 2026-07-30.
OpenAI pricing table
Compare meters side by side before opening each calculator. Watch the unit carefully: a “cheap” host rate is not comparable to a per-GB or per-million-events rate. The source column links to the official page used for verification.

OpenAI services and APIs in this catalog
Each table row maps to a full service page: volume calculator, cost profile (what 1, 1k, and 1M units cost, and how far $100 goes), and the pricing documentation link. If OpenAI publishes included quotas on monthly plans, use the calculator for the variable part and read the inclusion on the official source.
For engineering and finops teams, the practical flow is: (1) list the meters your product actually hits, (2) fill real or peak volume, (3) sum the results instead of guessing a single “platform average.” Large platforms mix several counters—logs, APM, infrastructure, RUM—and budget misses start when every line is treated as the same meter.

Frequently asked questions about OpenAI
What does OpenAI bill for usage in this catalog?
There are 9 published meters for OpenAI, billed in units such as audio minute, character, generated video second, tool call, file search tool call. Each page shows the list unit price, the billing unit, and the date the figure was checked against the public source.
Which OpenAI meter has the lowest unit price here?
OpenAI TTS-1 text-to-speech lists $0.000015 per character. Use that page’s calculator to project daily and monthly volume before you lock a budget.
Do OpenAI monthly plans roll into the calculator figure?
When the source publishes a per-unit rate (per GB, per request, per seat, and so on), the calculator uses that linear list rate. Included quotas, monthly minimums, annual packs, and volume discounts still need to be read on the official docs—CostUse keeps the source and verification date visible on every service page.
How should I compare OpenAI services against each other?
Use the pricing table on this page and sort by what you actually consume: log ingest, hosts, spans, seats, and storage are not comparable on the same unit. Then run each calculator with your team’s real volume, not a generic placeholder.
