The same answer costs 2,000 times more on one model than another.

Providers publish price per million tokens, which is not comparable across models. This index prices one standard answer, 1,000 input tokens plus 500 output tokens, across 100 models from 29 providers. Last updated August 20, 2026.

Headline figures

  • Cheapest answer: $0.000053 on Ling-3.0-flash (inclusionAI).
  • Median answer: $0.0019 on Kimi K2 Thinking.
  • Most expensive answer: $0.105 on Claude Opus 4.7 (Fast) (Anthropic).
  • Spread from cheapest to most expensive: about 2,000 times.

How this is calculated

One standard answer is 1,000 input tokens, roughly a prompt with a couple of paragraphs of context, and 500 output tokens, roughly a substantial reply. Every model is priced on that identical workload: (input rate x 1,000 + output rate x 500) divided by 1,000,000.

Change the mix and the ordering shifts, which is the point: a model with cheap input and dear output wins on short prompts and loses on long replies. The formula is published so you can recompute it against your own mix.

Sources and limits

  • Prices are public list rates from the OpenRouter model catalogue, in USD per million tokens, fetched August 20, 2026.
  • They exclude prompt caching discounts, batch pricing, and negotiated volume rates. Real bills at scale run lower.
  • Cost is not quality. A model 2,000 times cheaper is not 2,000 times worse, and on many everyday tasks the gap is small.
  • The credits column is what Whizi charges per message on its own plans, shown for the 89 models it meters individually. It is not a provider rate.

Questions

Why price an answer instead of a million tokens?

Because nobody buys a million tokens. Providers quote input and output separately at different rates, so two models can look close per million and differ by a lot on the same real task. Pricing one fixed workload makes the numbers comparable.

Which model is the best value?

Value depends on the task. The useful reading is that the middle of this table is within a few hundredths of a cent per answer, so for most everyday work the price difference between good models is negligible and the choice should be made on output quality.

How often is it updated?

Prices are refreshed from the provider catalogue and the page carries the fetch date, currently August 20, 2026. Rates in this market move often, so check the date before quoting a figure.

What are Whizi credits?

Whizi charges a message against a monthly allowance, and expensive models cost more credits than cheap ones, from 1x up to 20x. The column shows that multiplier so you can see how a provider list rate maps onto a flat subscription.
