Common questions
How many tokens is 1,000 words?
On average, 1,000 words is approximately 1,333 tokens. This is because one token equals roughly 0.75 words (or 4 characters) in English. Code, non-English text, and special characters may use more tokens per word.
How do you calculate AI API cost?
AI API cost is calculated by multiplying your token count by the model price per million tokens. Most providers charge separately for input tokens (your prompt) and output tokens (the model response). Output tokens are typically 3 to 6 times more expensive than input tokens.
