OpenAI · API + Codex
Every OpenAI dollar, accounted for.
API usage, ChatGPT seats, and Codex. One view of what your org spends on OpenAI, and what it produces.
The API bill and the ChatGPT bill don’t reconcile. Codex lives on both.
- Spend by team, project, and model, synced from your org chart
- Codex cost per developer, across both bills
- Cost per output: spend tied to work actually delivered

THE WHOLE STACK
Start with OpenAI. Measure everything.
Larridin measures AI spend across every vendor your org runs: OpenAI beside Claude, Gemini, Cursor, and Copilot, plus cloud-billed usage and the agents you built in-house.
- Every vendor, seat, and agent in one spend model
- Attributed by team, department, and use case
- One ROI number across the stack
EVERY VENDOR, ONE SPEND MODEL
OpenAI is one column in the ledger. The same spend model covers every AI vendor, seat, and agent your org runs, attributed by team, department, and use case.
HOW IT ADDS UP
However your org buys AI, the spend lands in one place.
Consolidated first, then owned, then tied to output.
CONSOLIDATE
The whole AI bill, reconciled
Platform tokens, seats, credits, and cloud-billed usage from every vendor: one spend model across the stack.
ATTRIBUTE
Each dollar gets an owner
OpenAI’s Costs API stops at projects and keys, and every vendor has its own version of that ceiling. Larridin maps them all to teams, departments, and use cases from your org chart.
PROVE ROI
Spend meets the work it paid for
Cost per output, hours returned, adoption: measured from PRs and tickets, ready for the budget review.
FULL OPENAI COVERAGE
Codex credits and workspace-agent runs land in the same ledger as API tokens and seats, attributed to the same teams. Seat utilization lives on the ChatGPT Enterprise page.
WHAT IT PRODUCED
OpenAI spend, tied to work delivered.
Cost per PR, hours returned, and adoption, measured from the work itself. The budget review starts with a number.
- Cost per output for API, seats, and Codex
- Hours returned, counted from PRs, tickets, and reports
- Adoption trends by team and workflow
THE OPENAI LEDGER
Every OpenAI surface, one ledger.
Platform tokens, seats, credits, and Codex reconciled, then allocated by team, project, and cost center.
All your AI spend, OpenAI and beyond, in one place. Attributed by team, department, and use case.

CODEX
What Codex costs, per developer.
Codex burns plan credits in the admin console and API tokens on the platform bill. Larridin joins them into cost per developer and cost per PR.
- Plan credits and API tokens in one number
- Cost per developer, by team
- Codex spend next to the PRs it shipped
ONE VIEW
Take one screen into the budget review.
Every vendor’s spend, next to the work it produced. OpenAI in context, not in a silo.
Output attribution. Work delivered across the stack, measured from the systems it lands in, beside what it cost.
Every vendor, one column each. OpenAI sits beside Anthropic, Cursor, and Copilot, so the budget conversation covers the whole stack.
OpenAI in context. The vendor you came to track, measured against everything else you run.
HOW IT CONNECTS
Connected in a day.
Connect OpenAI
Authorize Larridin with an org Admin key for the platform, and connect the ChatGPT admin console for seats, credits, and Codex. Nothing in your codebase changes.
Allocation syncs
Projects and keys map to teams and cost centers from your org chart. Every token, seat, and credit rolls up automatically.
Output attaches
Work delivered with ChatGPT and Codex lands next to what it cost: cost per output from the first scan.
FAQ
Questions OpenAI customers ask us.
How do I track OpenAI API costs by team?
OpenAI’s Costs API groups by project, key, user, and model, and only when asked. Larridin maps those projects and keys to teams, departments, and use cases from your org chart, without renaming a single key.
Why doesn’t the usage dashboard match our invoice?
The dashboard is delayed, reported in UTC, and exports cap at 60 days; since April 2026, Enterprise invoices no longer itemize API costs. Larridin keeps a daily ledger from the usage APIs, so finance isn’t working from a 60-day export window.
How much does Codex cost per developer?
Natively there is no one number: Codex burns plan credits in the admin console and API tokens on the platform. Larridin joins both into cost per developer and cost per PR.
Do ChatGPT credits cover Codex, or is that billed separately?
Both. Plan seats include Codex credit allowances, and API-key usage bills separately at token rates. That split is exactly why the two need one ledger.
Does it cover Azure OpenAI?
Yes. OpenAI usage billed through your Azure subscription is attributed the same way as platform spend, so the OpenAI number is whole whichever contract it rides on.
How do we prove ROI on OpenAI spend?
From the work itself: PRs, tickets, and documents delivered with ChatGPT and Codex, measured per team and per dollar, ready for the budget review.
CHEAP TOKENS AREN’T THE GOAL
Useful ones are.
Optimize cost per outcome.
Larridin ties model spend to the work it produced, so you optimize for cost per outcome, not cost per token.
