A new browser-based tool, LLMCostCalc, has been developed to help users compare the API costs of various large language models. It allows users to input their daily call volume and prompt sizes to estimate monthly bills for models like Claude Haiku, Sonnet, and Opus, as well as GPT-5 mini, Pro, and the base GPT-5, and Gemini 2.5 Flash and Pro. The calculator highlights significant cost differences, with one scenario showing a 230x spread between the cheapest and most expensive options for the same workload, and also models savings from context caching and distinguishes between input and output token costs.
