Integration · OpenAI
Bring your OpenAI usage and invoices into the unified AICosts.ai dashboard, under 2 minutes per upload.
Setup in 4 steps
Export your OpenAI usage or invoice
Download a usage CSV or invoice PDF from the OpenAI billing portal. Or, instrument your app to push usage events to our developer API.
Upload it to AICosts.ai
Dashboard → Platforms → Add OpenAI → upload the file. Re-upload anytime to refresh.
Watch it parse
We parse the file and email you when it's done. Events pushed through the developer API land immediately.
Slice by model and feature
Break down GPT-4o vs GPT-4o-mini vs o1 spend, per day. Assign OpenAI a cost center if you need the spend attributed to a team or project for chargeback.
What you get
Invoice-accurate totals, not rate-card estimates
We parse what OpenAI actually billed you. Whatever discounts your invoice already reflects are in the number, rather than a token count multiplied by a public price list.
Per-model breakdown
See GPT-4o against GPT-4o-mini against o1 as separate lines, so a change in model mix is visible rather than buried in one blended figure.
Line-item detail per billed unit
Each parsed line keeps its unit type, quantity, rate, and cost, so you can see what you were charged for and at what rate, not just a monthly total.
Zero application code changes required
Upload your invoices and we never touch your SDK or request path. Off-path billing aggregation, not a proxy. (The developer API is the other option, and that one does mean writing code.)
Use cases
Spotting token growth month over month
Comparing input-token volume across invoices surfaces when few-shots, tool schemas, or retrieved context quietly grew.
Seeing the effect of a model swap
After moving traffic from GPT-4o to GPT-4o-mini, the per-model split shows how much of the bill actually followed.
Forecasting next month's OpenAI bill
The dashboard projects the next 30 days from your recent daily spend, with a confidence band, which beats eyeballing the console when the number matters for runway.
Frequently Asked Questions
Does AICosts.ai see my OpenAI prompts or completions?+
No, and not because we filter them out, but because we never have them. We never connect to your OpenAI account. The only thing we receive is the billing file you upload, or the usage events you choose to push through our developer API.
Do I need to give you an OpenAI API key?+
No. We don't ask for one and we have nowhere to store one. Ingestion is you uploading an invoice or usage export, or your app posting usage events to our developer API with a key we issue.
How do I keep the dashboard current?+
Re-upload when a new invoice arrives, or push events continuously through the developer API. There is no polling on our side, so the cadence is entirely yours.
Does this work for Azure OpenAI?+
Yes, through the same upload flow, as a separate platform. Azure bills for it, so the file you upload is an Azure billing export rather than an OpenAI one, and the two sit side by side in the dashboard.
