CostPerPrompt
Live AI API Pricing & LLM Cost Calculators
CostPerPrompt is a live AI API pricing tracker covering 232+ models from vendors such as OpenAI, Anthropic, Google, Meta, DeepSeek, Alibaba, Cohere, Mistral, xAI, and more. It shows per-token input/output prices, cached input prices, and context window sizes, with data refreshed automatically (last update 2026-08-02).
The tool solves the problem of fragmented and frequently changing LLM pricing by pulling per-token rates from public listings into a single sortable table, then converting those rates into estimated monthly bills using built-in calculators that support caching and batch scenarios.
It's built for developers, product teams, and budget owners who need to compare model costs across vendors and plan API spending accurately.
