Official and OpenRouter prices checked daily
See what the same workload costs through a model provider or OpenRouter. Compare source-linked rates, include routing fees, and choose the channel that fits your stack.
Official direct pricing and OpenRouter pricing stay separate, so a cheaper route never gets mistaken for a provider price.

Pricing guides
Use focused comparisons when you need a direct answer about the cheapest APIs, one provider, or the major model families.
Compare the lowest verified token rates and learn when the cheapest list price can still cost more in production.

View price history →How to use the data
Start with the workload, not the model name. Estimate fresh input tokens, repeated cached context, output length, and monthly request count. LLM API Prices applies those inputs consistently so you can compare first-party and OpenRouter routes without mixing their prices or fees.
A lower list price is only useful when the model still meets your requirements. Test response quality, tool support, latency, availability, context behavior, and data policies before moving production traffic.
It calculates fresh input, cached input when a cache-read rate is available, generated output, cost per run, and monthly cost. For OpenRouter, you can optionally include the percentage charged when purchasing credits.
An official price is a verified first-party API rate linked to the model provider’s documentation. Open-weight models without a universal first-party hosted API are labeled instead of being assigned an invented price.
Taxes, regional premiums, batch tiers, priority processing, tool calls, storage, image or audio units, and special long-context rules are excluded unless the model note explicitly says otherwise.
Frequently asked questions
Providers usually charge separately for input tokens, cached input, and generated output. Multiply each token amount by its per-million rate, then add the components and monthly request volume.
Sometimes, but not always. Many OpenRouter inference rates match first-party prices, while some mapped routes differ. Credit purchase fees and operational features should be compared separately.
No. The calculator runs in your browser and does not ask for model-provider credentials, send prompts, or inspect your actual API usage.
Official sources and the OpenRouter model feed are checked daily. Last-known-good prices are preserved when a source fails, and suspicious official changes are held for review.
Comparison method
Official prices come from each model provider. Open-weight models without a first-party hosted API are labeled clearly.
OpenRouter prices come from its model API and remain a separate channel, with their own source and update time.
OpenRouter’s credit purchase fee is optional in the calculator, so it never disappears inside the token rate.
