How LLM token pricing works
Input and output tokens are priced separately
Most providers charge a different rate for the tokens you send (input) and the tokens the model generates (output). Output tokens are usually more expensive because generation requires compute. This converter handles both sides automatically.
Prices are shown per 1M tokens
Provider rate cards list prices per 1 million tokens. A price of $2.50 means you pay $2.50 for every 1,000,000 tokens processed. The converter also normalizes this to a per-1K-token rate so you can reason about small prompts.
Why token count matters
API bills, context window limits, and rate limits are all measured in tokens. Knowing the cost of a single request lets you forecast monthly spend and compare models before you integrate them.
