# Obolith

> Find the cheapest way to run AI. Obolith compares LLM API pricing, GPU cloud rental,
> vector databases, embedding APIs, object storage and LLMOps tools - normalised to the
> same units and re-checked every day.

Prices are collected from public sources (OpenRouter API, provider pages, the Vast.ai
market, hand-sourced seed data) and regenerated on every deploy. Not a quote - always
confirm on the provider's own site.
