About the Token Pricing Engine
OpenAI charges based on “Tokens”, which act as pieces of words used for natural language processing. As a rule of thumb, 1 token is approximately 4 characters or 0.75 words for English text.
Pricing Rule: Output (Completion) tokens are consistently more expensive than Input (Prompt) tokens because generating text requires more compute power than reading it. Always look to constrain the AI’s output length to save on API costs at scale.
