RunModels Cost Calculator

A handcrafted black-and-white static calculator for estimating AI model running costs, VRAM, RAM, DGX Spark sizing, and rough profit versus OpenRouter-style per-million-token pricing.

Local development

npm run dev

Open http://localhost:3000.

Vercel deployment

This repository is intentionally static. The source files live at the project root, and npm run build copies index.html, styles.css, and app.js into public/ for Vercel production output.

Deploy from the Vercel dashboard

1. Import this Git repository in Vercel.
2. Keep the framework preset as Other.
3. Use Build Command: npm run build.
4. Use Output Directory: public. The build script creates this folder and copies the static assets into it.
5. Deploy.

Deploy from the CLI

npm install -g vercel
vercel
vercel --prod

Checks

npm run build

The build script creates public/, copies the static assets into it, and validates the emitted JavaScript with node --check public/app.js.
