Carry Indices

The reference price for intelligence.

Independent benchmarks for the price of AI inference, built from verifiable inputs, overseen by an index governing board and published every day.

The indices

Two measures. One flagship.

CICI is the flagship benchmark for the price of inference. CRTI shows what the market actually pays for it. Each is computed from its own inputs and published daily.

The price of AI inference at constant capability, so every move in the index reflects the cost of intelligence itself.

Principles

Built to be trusted.

Four principles guide every value we publish.

01

Verifiable inputs

Model prices come from each vendor's own published price page, so anyone can check the inputs behind the number.

02

Constant capability

As models grow more capable and more affordable, holding capability constant lets the benchmark follow the price of intelligence itself.

03

Approved rules, automatic publication

The methodology and every change to how the indices are built are approved before they take effect. Each day's values are then calculated and published automatically by that approved process.

04

Versioned and on record

Each methodology version is frozen and kept on record. A change to the base methodology is released as a new, named version.

Governance

Governed like market infrastructure.

The indices are run under a governance framework modelled on established commodity benchmarks, with clear separation between those who calculate, those who oversee and those who use them.

Enquire about the governing board

Index governing board

Independent oversight of the methodology, its changes and its use as a benchmark.

Index administrator

Approves the methodology and any change to how the indices are built, and runs the approved process that publishes the indices every day.

Methodology

The full rulebook is shared with members of the governing board under a confidentiality agreement.

Version history

Every published methodology version stays on record and can be retrieved.

Questions

Common questions.

What is CICI?

CICI is Carry's flagship benchmark for the price of AI inference. It measures the price of inference at constant capability, so every move in the index reflects a change in the cost of intelligence itself. It is designed as a reference for hedging and settlement.

What is CRTI?

CRTI measures what the market actually pays for AI inference, in US dollars per million tokens, using realised prices and observed usage. It is computed from its own inputs, independently of CICI, and is designed for market monitoring and research.

Where do the index inputs come from?

Model prices are taken from each vendor's own published price page, so anyone can check the inputs behind the published values.

How often are Carry's indices published?

Both indices are published daily.

How are the indices governed?

An index governing board provides independent oversight of the methodology, its changes and its use as a benchmark. The methodology, and any change to how the indices are built, is approved before it takes effect. Each day's values are then calculated and published automatically by that approved process. Each methodology version is frozen and kept on record.

Is the index methodology public?

The full rulebook is shared with members of the governing board under a confidentiality agreement.

How can I license Carry index data?

Index values and their history are available under licence for benchmarking and settlement, risk and reporting, and research. Contact [email protected] to discuss a licence.
