LLM Cost Lab

LLM Cost Lab is a free LLM API pricing reference and cost-calculator suite for developers and teams building with AI. Compare 88 models across 18 providers in one sortable table with input, output and cached rates per 1M tokens, then price your real workload with 17 calculators: API cost, cost per request, token counter, RAG pipeline, AI agent cost, prompt caching and batch savings, fine-tuning, embeddings and GPU rental. A monthly price index tracks how rates move across the market. Every rate is read from the provider's own pricing page and shows the date it was checked, and retired models are flagged instead of quietly left in. Free, no signup, nothing to install.
