AI Price Index

What does AI really cost?

The price of intelligence is falling – and we measure it daily. The AI Price Index shows what 1 million tokens cost across the leading AI models: in euros, from the official price lists, at the current ECB exchange rate.

AI Price Index
€2.97
Median price per 1M tokens (weighted 3:1 input:output)

Median of 10 current frontier models – one flagship per major provider.

Intelligence costs between €0.054 (Amazon Nova Micro) and €17.56 (Claude Fable 5) per 1M tokens – a factor of 326. Which model pays off depends on the task.

Blended = a (3:1) weighted mean of input and output price, so one number is comparable across models. Standard list prices, excluding cache/batch/promo discounts.

The price of intelligence over time

The AI Price Index, day by day. The curve grows from launch – it can only be measured forward, never reconstructed after the fact.

The history starts recording today and grows from tomorrow. For now you see the current snapshot.

How we measure

Honest and verifiable – only official price lists and the ECB reference rate.

  1. 1
    Official price lists

    USD list prices come straight from the provider pages (OpenAI, Anthropic, Google, Mistral, DeepSeek, xAI, Alibaba, Meta hosts, Cohere, Amazon).

  2. 2
    Converted at the ECB rate

    Every day we convert to euros at the European Central Bank's official reference rate – so the price moves even when the dollar tariff is stable.

  3. 3
    One comparable number

    Per model we form a blended price (input:output weighted) so models can be compared with a single figure.

  4. 4
    Forward-only history

    The daily values build the index history. Providers overwrite their price pages without keeping history – our curve grows from launch.

We show standard on-demand list prices, not cache, batch or promotional discounts. Open models (e.g. Llama) have no API price of their own – there we show a major host's price. We are not affiliated with any provider.

Frequently asked questions

What is the AI Price Index?

The median price of about a dozen current frontier models for 1 million tokens – in euros. A single number showing what intelligence at the frontier costs right now.

Where do the prices come from?

From the providers' official price lists (in US dollars), converted daily to euros at the ECB reference rate. They are standard list prices without cache, batch or promotional discounts.

What does “blended” mean?

Input and output tokens are priced differently. The blended price weights both (3:1 by default) so a model needs a single, comparable figure.

Why does the index move when providers rarely change prices?

Because we convert to euros daily at the current ECB rate. The euro price tracks the exchange rate – and jumps the moment a provider changes its dollar tariff.

Are these the costs I actually pay?

These are list prices. Your effective cost depends on caching, batch processing, volume discounts and how many tokens your tasks need – which we work out concretely in the AI ROI calculator.

All figures without guarantee. Standard on-demand list prices from the providers, in euros at the ECB reference rate; see the per-model source for the as-of date. No tax included. i6eal is not affiliated with any of the named providers. Model and company names belong to their owners.
