AI//COST
Independent, dated price index for AI models and APIs
About AI//COST
AI//COST is an independent price reference for people who build with or buy AI models. It tracks API token rates for major labs, along with subscription plans and AI agent tools, so readers can see what a model actually costs before committing.
Each rate is checked manually against the vendor's own pricing page and shown with the date it was verified. The site pairs the data with per-model pricing pages, benchmark leaderboards, two-way comparisons, capability Q&A and a glossary. Calculators turn rates into a bill for API usage, token counting, subscription versus API, embeddings, fine-tuning, agent cost, image, video and text-to-speech generation.
A journal covers pricing analysis and cost optimization topics such as prompt caching, batch discounts and rate limits, and a news log records price changes and model releases. A public corrections log records fixes, and the site discloses its affiliate links.
