Enterprise cost intelligence and autonomous SDLC platform company Harness has launched AI Budgets, a new service to help engineering or FinOps leaders set weekly limits by team, developer, model, or project. Part of the Harness Cost Management Agent service, AI Budgets turns cost policies into “live limits” to help teams keep AI spend in check. This might be a timely development, what with news last week of Accenture telling employees it will now fund just $29 a month per person for Claude, after some staff spent up to $1,000 a month. So how does it all tally up?
To create this new service, Harness tested it on its own AI bill first. Average weekly spend per developer fell from $184 to $115, and cost per million tokens dropped from around $1.80 to $0.80 the week governance went live.
According to Harness, with AI Budgets, the Cost Management Agent turns AI cost policy from a document everyone signed once and forgot… into a limit that an organisation can see working.
“In our last post, we showed why 73% of organizations have an AI cost policy, but only 13% can tell whether it’s working. Most teams have written the rule, but almost none can say on any given day whether it’s holding. A policy can’t catch the developer who spun up an oversized model or the retry loop that quietly tripled a bill overnight, and it won’t know a budget was crossed until the invoice says so,” said Patrick Brogan, director of FinOps Advisory at Harness.
Every dollar is attributed, every threshold fires on time
The organisation thinks that this is the same “visibility and enforcement problem” FinOps teams have been solving for cloud spend for years. Harness is opening access to AI Budgets inside the Harness Cost Management Agent, so that AI Budgets “sets a real limit” on AI spend, scoped to whatever unit an organisation actually manages against i.e. team, developer, model, or project.
Once a budget is live, every dollar is attributed, every threshold fires on time… and the audit trail fills itself.
All spend has an owner & a reason
AI Budgets runs in the same Cost Management Agent that already attributes cloud, AI, and engineering spend to an owner and a reason. A budget only means something if the agent already knows, down to the session or the model, where the money is going, so budgets are accurate from day one. Every warning, block, and approved increase is logged to the same immutable audit trail Harness uses across FinOps, DevOps, and security governance, and that record is ready to export for SOC 2, ISO 27001, or your next FinOps review.
How it works
- Users set the budget at the level that matters. Scope budgets to the unit an organisation actually manages spend against, whether that’s a team, developer, model, or project.
- A weekly cadence. A monthly budget lets someone burn the whole forecast in week one. A weekly reset keeps the feedback loop tight and makes a breach cheap to recover from.
- Graduated notification. At 90% of budget, spend moves into a “warn” tier: the person is notified, but nothing is restricted yet. That first signal is just a nudge.
- A real limit past 100%. Once weekly spend crosses the budget, access pauses until the next weekly reset or until someone approves a request for more.
- Self-service requests, tiered by amount. Raising a budget is a same-day, in-product request rather than a ticket. Small increases clear quickly, and larger ones go to the person with the authority to approve them.
Within 48 hours of setup, the first budget alert fires, and a developer who didn’t know they were overspending gets a heads-up before any limit applies. Within one week, a FinOps team stops being the “AI police” and becomes the team that enabled safe AI adoption. The budget acts as the guardrail, so no one has to be the person saying no. Within one month: cost per million tokens becomes a metric engineering leadership tracks alongside velocity.
Visibility first, enforcement second
“Before any budget goes live, the Cost Management Agent attributes spend by user, provider, model, and token type, and surfaces a single number worth tracking: cost per million tokens. Total spend tells you how much was used. Cost per million tokens tells you how well it was used. A team can double its usage and still cut its bill if it’s using the right model for the job,” noted Brogan.
The agent also surfaces token-level detail, input, output, cached, and reasoning tokens, so cache behaviour that’s quietly driving hidden cost is visible instead of buried in a monthly total.
AI Budgets isn’t limited to one tool or one provider. It ingests cost and usage data from every major AI provider into a single view, so nobody has to check nine dashboards to understand one bill.
