FAQ
How is the API cost calculated?
Cost per request = input tokens × input price + output tokens × output price, with prices per 1 million tokens. Cached input tokens use the cached-input price when the provider publishes one.
How many tokens is a word?
For English text, 1,000 tokens is roughly 750 words. Code, other languages and images use different amounts, so check with your provider's tokenizer for exact counts.
Does the calculator include batch or long-context pricing?
No. It uses the standard official rate. Batch processing is usually cheaper, and some models charge more above a long-context threshold.
