LLM FinOps · Cost attribution & routing

Know what every token costs. Then pay less for it.

Your inference bill is one opaque line item growing 20% a month. Brevo breaks it down by feature, customer, and prompt — then cuts it with eval-safe model routing and semantic caching.

Drop-in proxy · 14 providers supported · No prompt data stored

The fastest-growing line item nobody owns.

AI features ship fast. The bill arrives later — and nobody can say which feature, customer, or prompt caused it.

One opaque invoice

Provider bills show tokens in, tokens out, dollars due. They don't show that one customer's pathological prompts account for 14% of your spend.

Costs outrun revenue

Inference spend compounds with usage. Teams routinely discover their flagship AI feature has negative gross margin — months after launch.

Everyone's job, no one's job

Engineering picks models, product picks features, finance gets the invoice. Without shared attribution, cost reviews turn into blame reviews.

See it. Route it. Cache it. Cap it.

Four layers, each one optional, all behind a single drop-in proxy.

Cost attribution

Tag requests by feature, customer, and prompt template. See unit economics in real dollars: cost per request, per user, per workflow — live.

Eval-safe model routing

Routes each request to the cheapest model that passes your eval suite — never on price alone. Quality regression blocks the route automatically.

Semantic caching

Recognizes when a request is a paraphrase of one you've already paid for and serves the cached answer in 40 ms — at zero marginal cost.

Budgets & anomaly alerts

Per-feature budgets with soft and hard caps. A runaway agent loop gets throttled at 2 AM and summarized in Slack by 9 — not discovered on the invoice.

Live in an afternoon, saving by Friday.

Swap one base URL

Point your OpenAI, Anthropic, or open-model SDK at the Brevo proxy. No code changes beyond the endpoint — keys stay yours.

Watch attribution fill in

Within an hour you'll see spend broken down by feature and customer, with the top three savings opportunities ranked by dollar impact.

Turn on the savings

Enable routing and caching per feature, gated on your own evals. Most teams cut 30–45% in the first month without touching product quality.

The numbers, plainly.

“We thought our summarization feature cost us about $6k a month. Brevo showed it was $19k — and that two-thirds of it passed evals on a model a tenth the price. We cut the bill 38% in three weeks, and for the first time our board deck has real per-customer AI margins in it.”
