How to Use the Token Pricing Calculator

Predicting the infrastructure costs of scaling an LLM application is historically opaque. This tool provides real-time cost visibility for engineering teams and founders. Simply adjust the daily token volume slider and set your expected input/output ratio to see exactly how much your agentic workflows will cost across the major frontier models.

Key Features:

  • Live Market Pricing: Automatically fetches the most current API token prices for OpenAI (GPT-4o), Anthropic (Claude 3.5), Google (Gemini 1.5), and Perplexity.
  • Dynamic Ratio Adjustments: Use the toggle buttons to simulate different architectural loads (e.g., heavy RAG inputs vs. heavy generative outputs).
  • Volume Scaling: Interactive slider to forecast costs from 1 million to 100+ million tokens per day.
  • Interactive Visualizations: Instantly compares cost efficiency via bar charts, scatter plots, and clean data tables.
