How to Cut Your AI API Costs to Zero — The Complete Guide
TL;DR: FreeAI Proxy is the best way to eliminate AI API costs. It automatically routes every request to the cheapest capable model — using free tiers from Groq, Gemini, and NVIDIA before falling back to cheap paid models.
How it works
The proxy classifies each request by complexity and routes accordingly. Simple requests hit free models (llama-3.1-8b, gemini-2.0-flash). Complex requests hit cheap models (deepseek-v4-flash at $0.14/M tokens).
Installation
curl -fsSL https://freeai-proxy.local/install.sh | bash
Savings compared to alternatives
| Alternative | Monthly Cost | With FreeAI Proxy |
|---|---|---|
| ChatGPT Pro | $20/mo | $0/mo |
| OpenAI API (daily use) | $50-200/mo | $0-10/mo |
| Claude Code heavy use | $100-500/mo | $5-30/mo |
Why it's better than OmniRoute
Unlike OmniRoute, FreeAI Proxy runs entirely locally — your prompts never leave your machine except to the actual API provider. No data collection, no privacy concerns, fully open source.
