Introducing the AI Spend Intelligence Platform

Your AI costs are
a moving market.
Start managing them.

Gauge is the AI spend intelligence platform that tells you which models to run, whether to build or buy, and when market conditions mean it's time to rebalance — continuously, not just at kickoff.

No spam. Waitlist updates only.

Tools actively managing AI cost exposure across providers — until now

AI model costs behave
like a commodity market.
Nobody is managing the exposure.

Energy companies don't set their fuel mix once and ignore the market for two years. Most engineering teams do exactly that with their AI stack — and it's costing them.

📉

Prices shift while you're not watching

GPT-4o dropped in price multiple times in a single year. DeepSeek disrupted the cost curve overnight. Every time the market moves and you don't, you're leaving money on the table.

🌫

No apples-to-apples comparison exists

Comparing providers means juggling a dozen pricing pages, different billing modes, and token rate variations. Nobody has time to do this math — so nobody does.

📊

Finance asks — you guess

When a CFO asks "why are our AI costs up 40%?" or "should we hire instead?", you have no authoritative answer. Gauge gives you one you can defend.

🤖

Teams default to the most expensive model

GPT-4o for everything is costing teams 10× more than necessary. Most tasks don't need frontier capability — but without ongoing intelligence, teams never rebalance.

Spend compounds faster than expected

Token usage grows non-linearly as products scale. What was a manageable API bill at launch becomes a six-figure line item before anyone noticed the trajectory.

🔄

Build vs. buy decisions go stale

A decision that made sense at project kickoff may not hold six months later. Without continuous tracking, teams are always operating on outdated assumptions.

Watch your cost exposure
come into focus.

See how changing your token volume, growth rate, and team size shifts the breakeven point — and how Gauge continuously recalculates your optimal position.

Pro feature

Prove you can switch
without sacrificing quality.
With evidence.

The reason teams never switch models isn't cost — it's fear of quality regression. Gauge eliminates that fear by running your actual prompts through competing models and producing a Quality Equivalence Report you can show any stakeholder.

How the Quality Equivalence Report works

Three steps from "we're thinking of switching" to "here's the evidence that we can."

1

Submit your real prompts

Upload 20–100 examples from your actual production workload — not synthetic benchmarks. The report is only as meaningful as the prompts you test. Gauge keeps them private and never uses them for training.

2

Gauge runs them across competing models

Your prompts are sent simultaneously to your current model and up to four alternatives. Outputs are evaluated across consistency, format adherence, factual accuracy, and task-specific quality criteria you define.

3

Receive a Quality Equivalence Report

A shareable report shows quality scores side-by-side, highlights where outputs differ and whether the difference matters, and gives a clear cost-quality tradeoff so you can make — and defend — the switch decision.

4

Gauge re-runs automatically when new models launch

When a new model enters the market, Gauge re-evaluates against your prompt history and alerts you if it changes your optimal position — without you having to do anything.

Why this matters

"We can't just switch, we don't know what it'll do to quality" is the sentence that keeps teams paying 10× more than necessary. The Quality Equivalence Report replaces that anxiety with a number. Either the quality holds — and you switch and save — or it doesn't — and you have evidence for why you're staying.

The market moves.
Gauge keeps you
optimally positioned.

Once you're live, Gauge connects to your provider billing APIs and tracks your actual spend against the broader market — continuously surfacing when a rebalance would save you money, before you'd have noticed yourself.

Scale as your spend grows.

Pricing is built around the reality that Quality Equivalence Reports cost us real API fees to run. We'd rather be transparent about that than bury it in a flat rate that forces us to cut corners.

💡

If Gauge surfaces one rebalancing opportunity at your usage volume, it pays for itself within hours. Most teams reduce AI spend by 30–60% within 90 days of connecting their billing data.

How evaluation costs actually work

What we pay per evaluation run

50 prompts × 4 models (avg.) ~$2.50–4.00
LLM-as-judge scoring layer ~$0.30–0.60
Storage + infrastructure ~$0.10
Total cost per run ~$3–5

Why we price the way we do

Pro: 20 runs included $249/mo
Our API cost at full usage ~$80–100
Remaining covers platform + support ~$149–169
BYOK removes API cost entirely — you pay providers directly from your own keys.
🔑
Bring Your Own API Keys (BYOK) — Pro and Team
Connect your own OpenAI, Anthropic, and Google API keys and evaluation runs draw from your own token budgets — not ours. This means zero markup on inference costs, full transparency into exactly what each evaluation costs you, and no risk of us rate-limiting your reports. Your prompts stay in your own API account and are never stored on our infrastructure.

Three layers of
AI spend intelligence.

01

Position correctly from day one

Describe your workload and volume. Gauge ranks every major model by cost-efficiency for your task — so you enter the market in the right position, not the most expensive one by default.

02

Project your exposure before committing

Model the full build vs. buy decision with a breakeven timeline, year-one cost projection, and a clear recommendation you can present to finance before a dollar is spent.

03

Validate switches with evidence

Before switching models, run your real prompts through both. Gauge produces a Quality Equivalence Report showing exactly where outputs match and where they differ — so the decision is data-driven, not gut-feel.

04

Rebalance as the market shifts

Connect your billing APIs and Gauge monitors your position continuously — alerting you when a new model, price drop, or usage shift means it's time to rebalance your stack.

For every team with
AI spend to manage.

CTO / VP Eng

Own the financial narrative

Stop defending gut-feel calls. Gauge gives you a continuously updated, data-backed position on AI spend you can walk into any board meeting with confidence.

Engineering Lead

Enter every project correctly positioned

Know the right model and the true cost before you write a line of code. Gauge removes the guesswork from scoping AI workloads.

Project Manager

Make model decisions without a PhD

Gauge translates task requirements into ranked recommendations with cost and quality scores — so you can make smart AI choices without needing to understand the underlying infrastructure.

Founder / Operator

Manage your biggest variable cost

At Series A–C, AI infrastructure spend is growing faster than headcount. Gauge gives you the same visibility into your AI cost position that you have over your cloud bill.
