Your Boss Asked What AI Will Cost.
Answer in 5 Minutes.
The top 14 providers. Their top models. Your real images. We built the benchmark that didn't exist. A head-to-head comparison of every leading AI platform, scored against your actual content with a board-ready report showing real per-image costs, not token math. No engineering team. No coding. No guesswork. Just upload your images and get the definitive answer.
Choosing an AI Provider Shouldn't Require an Engineering Degree
Every company adopting AI hits the same wall:
The board says “go.” You need to know what it costs. So you go to the provider websites and find pricing in “tokens” — a unit nobody in your finance team has ever heard of. You ask your dev team to run a comparison and they say it'll take 3-6 weeks. Your budget meeting is Friday.
You need a number. Not a science project.
CostFunction gives you that number. Upload your images, pick providers, and get a professional report that tells you exactly what AI will cost per image, per month, and per year — in dollars, not tokens.
From Upload to Board Deck
in Four Steps.
No complex integrations. No learning curve. Just results.
Upload Your Images
Drag and drop the actual images from your use case. Not stock photos, not benchmarks — your real work. We normalize everything so every provider gets the exact same test. Apples to apples.
Tell Us What Matters
Cost? Speed? Quality? Pick your priorities and we'll weight the comparison to match your business goals.
Choose Your Providers
Not sure where to start? Use our curated picks — the most popular and proven providers, pre-selected for you. Want to go deeper? Browse all available models.
Get Your Report
In about 5 minutes, download a comprehensive PDF report. Executive summary with our recommendation on page one. Detailed comparison data behind it. Ready to attach to a budget proposal, vendor selection memo, or board presentation.
A Report That Speaks Business,
Not Engineering.
Every report includes everything you need to make a confident decision — and defend it.
Executive Summary & Recommendation
Which provider we recommend for your specific use case and why — written in plain language your CFO can read.
Cost Per Image Breakdown
Not cost per token. Not cost per million input characters. Cost per image. Multiply by your volume, get your monthly budget. Done.
Side-by-Side Quality Comparison
See how each provider described your images, what keywords and tags they generated, and how their analysis quality stacks up.
Content Safety Screening
Every image is checked for safe-for-work status across all providers. Know which providers catch what your brand guidelines require.
Speed & Performance Data
How fast each provider responds. Because if you're processing 50,000 images a month, latency matters.
The Full 100 Pages
Every image, every provider, every metric. Descriptions, keywords, thumbnails, response times. The backup documentation that proves you did your homework.
Why Teams Trust CostFunction.
Your Data, Not Synthetic Benchmarks
We test with your actual images, not generic datasets. Your results reflect your real-world costs and quality — not a lab experiment.
Apples-to-Apples Methodology
Every provider receives the same normalized images and the same standardized prompts. The only variable is the provider itself. A comparison you can defend in a meeting.
Comprehensive Coverage
From OpenAI and Google to emerging providers most people haven't heard of yet — we test them all so you don't have to.
No Technical Skills Required
No API keys. No code. No command line. If you can upload a photo and click a button, you can use CostFunction.
Export How You Need It
PDF for your stakeholders. CSV for your analysts. JSON for your dev team. Default is a clean, professional PDF ready to share.
5-Minute Results
What takes weeks of manual API testing happens in about 5 minutes. Start a comparison and have a complete cost report before your coffee gets cold.
Your AI Decision Doesn't
End at Purchase.
AI providers change pricing, update models, and shift capabilities constantly. What was the best choice last quarter might not be the best choice today.
Monthly Monitoring Reports
We re-run your original comparison every month with the latest models and pricing. You'll know immediately if a better option has emerged or if your current provider has changed.
Invoice Verification
Tell us what you're being charged. We'll tell you if the math adds up. No more paying AI bills on faith.
New Provider Alerts
When a new model launches that's relevant to your use case, we'll test it automatically and let you know if it's worth switching.
