What does "cost per token" mean?
Tokens are the basic units that AI models use to process text. Generally, 1,000 tokens ≈ ~750 words. The cost per token determines how much you pay for each unit of text processed by the model.
Formula: Total Cost = (tokens / 1,000) × price per 1K tokens
Examples
Example usage: A 500-word prompt + 300-word response ≈ ~1,067 tokens total.
- • 1,000 tokens ≈ ~750 words of text
- • Short email: ~200-400 tokens
- • Blog post: ~1,000-3,000 tokens
- • Research paper: ~10,000+ tokens
