Price Per Token

This web application provides a specialized tool for developers, researchers, and businesses working with large language models (LLMs) to accurately estimate and compare the pricing of API calls across a wide range of providers. At its core, the platform functions as both a token counter and a cost calculator. Users can input a prompt directly into a text field, and the tool instantly counts the number of input tokens and output tokens required, then calculates the total cost based on the selected model and provider. The system covers over 300 different LLM models, including popular ones like GPT-5, Claude, Gemini, Llama, DeepSeek, and many others. For each model, the calculator retrieves the current per‑token pricing rates for both input and output, allowing users to see precisely how much a given request would cost. Beyond simple prompt cost estimation, the tool offers a comparative view: users can select multiple models or providers side by side to see which combination yields the lowest per‑call cost for their specific use case. This is particularly useful for teams that need to balance budget constraints with performance requirements when choosing an LLM provider. The platform also includes a "token usage" breakdown that displays how many tokens are consumed by different parts of the prompt (e.g., system instructions, user messages, context) so that developers can optimize their prompts to reduce token consumption. One notable feature is a downloadable PDF guide titled "8 Ways to Use Fewer Tokens," which provides practical tips for reducing token usage and saving on API costs. This guide is offered through a newsletter subscription, and visitors can download it immediately after subscribing. The tool updates its pricing data regularly to reflect changes in provider
