Token counts vary by tokenizer and model; non-OpenAI counts are estimates. Cost is an estimate and provider pricing can change. See each model's source on the pricing page.

Comparing models on one workload

The fair way to compare language models is to hold the workload fixed (same input and output tokens, same volume) and vary only the model. That isolates price from prompt differences and shows the true cost gap, which is often larger than the headline per-token rates suggest once output pricing is included.

FAQ

Do cheaper models cost more in the end?

Sometimes. A weaker model may need more tokens, retries or a bigger prompt to hit the same quality, erasing its per-token advantage. Compare on your real task.
