AI Token Cost Calculator

AI language models like GPT-4, Claude, and Gemini charge based on the number of tokens processed. A token is roughly equivalent to 4 characters or 0.75 words in English. Understanding token costs is crucial for budgeting your AI application or workflow.

What Are Tokens?

Tokens are the basic units that AI models use to process text. Both your input (prompt) and the model's output (response) are measured in tokens. Different models have different pricing for input and output tokens.

Why Do Costs Vary Between Models?

Different AI models have varying capabilities, speeds, and operational costs. More advanced models like GPT-4 Turbo or Claude 3 Opus typically cost more but offer superior performance for complex tasks. Lighter models like GPT-3.5 Turbo or Claude 3 Haiku are more economical for simpler applications.

How to Optimize Your AI Costs

• Choose the right model: Use lighter models for simple tasks and reserve premium models for complex reasoning.
• Optimize prompts: Write concise, clear prompts to reduce input token usage.
• Limit output length: Set maximum token limits for responses to control costs.
• Cache responses: Store and reuse common responses instead of making repeated API calls.
• Batch processing: Group similar requests together to reduce overhead.
