Price Per Token

Price Per Token is an open-source developer calculator and API designed to estimate the costs of Large Language Model (LLM) prompts and generations. It queries API pricing tables to provide real-time cost predictions across top LLM providers.

Key Features of Price Per Token

• Multi-Provider API Tracker: Features updated pricing for OpenAI, Anthropic, Google Gemini, and Cohere.
• Prompt Token Calculator: Estimates input token counts and costs using provider-specific tokenizers.
• Batch Run Estimator: Predicts total costs for executing high-volume batch testing and data generation tasks.
• CLI Tool Integration: Run CLI commands directly in build flows to track developer API expenditures.

Benefits of Using Price Per Token

• Prevent Cost Surprises: Estimate API bills before running heavy AI generation runs or regression test suites.
• Optimize LLM Choices: Easily compare models to select the most cost-effective provider for your task.
• Budget Enforcements: Set budget thresholds in dev pipelines to abort testing tasks if cost limits are exceeded.

QA teams managing costs for LLM validation can use Price Per Token to analyze API pricing across AI providers, helping optimize testing budgets.
