AI & LLM Economics
LLM API costs, token estimates, GPU memory, adoption ROI, and research-based job exposure — the numbers behind building with AI.
Calculators
6 tools- aiLLM API Cost Calculator (GPT-4o, Claude, Gemini)Estimate monthly API costs for GPT-4o, Claude, and Gemini from tokens per request and volume. See input vs output cost split. Prices as of 2025 — verify.
- aiToken Counter & Context-Window Fit CalculatorEstimate the token count of any text with the chars/4 words/0.75 heuristic, check if it fits 8k, 128k, 200k, or 1M context windows, and gauge API cost.
- aiAI Build vs Buy Calculator (API vs Self-Host)Compare the monthly cost of a hosted LLM API against self-hosting on your own GPUs. Find the break-even token volume and see which option is cheaper for you.
- aiGPU VRAM Calculator (Model Size & GPU Fit)Calculate the VRAM a large language model needs by parameter count and precision (fp16, int8, int4), then see which GPU it fits — from RTX 4090 to H100.
- aiAI Tool ROI Calculator (Payback on Adoption)Estimate the ROI and payback of an AI tool: enter hours saved per week, staff count, and cost to see monthly net savings, break-even months, and annual return.
- aiAI Job Exposure Score (Research-Based, Not a Prediction)An AI job exposure score built from published research (Eloundou et al. 2023, O*NET, Goldman Sachs): estimate your task mix, not a prediction about you.
