Model prices are fetched directly from the OpenRouter public API at page load. OpenRouter aggregates pricing from OpenAI, Anthropic, Google, Meta, Mistral, and many other providers — so you get one place to compare them all.
Enter your expected input tokens (your prompt + context) and output tokens (the model response). Use the search box to filter by model name or provider. Click any column header to sort. The "Total" column is your estimated cost per API call.
Not sure how many tokens your text is? Use the Token Counter tool to count tokens in your prompt before estimating costs. As a rough guide: 1,000 English words ≈ 750 tokens.
