One mailbox, read by a person
No form, no ticket queue, no chatbot. Everything below arrives in the same place — the prefilled subject lines just make it sortable at the other end.
Corrections are answered first, usually within a few working days.
What to write about
Six things worth an email
Anything not on this list is welcome too — these are just the ones that come up often enough to have a subject line.
A number looks wrong
The most useful mail we get. Prices change without announcement and benchmark results get revised, so corrections are read first and fixed ahead of everything else.
Include
- The page it is on, and which figure
- What it should say instead
- A link to the source, and the date you saw it
Press and analysts
Quoting a chart or a figure needs no permission — attribution and a link is enough. Write if you need context on how something was measured, or a version of a chart at a size that reproduces well.
Pitching an article
The blog takes outside contributions. Read the guidelines first: they set out what gets published, what does not, and how a pitch should look.
Data and licensing
For research use of the index in bulk, or to reproduce a large part of it somewhere else, ask here rather than pointing a scraper at the site. Requests that come with a described use case are usually straightforward.
Privacy
Questions about what is collected, or a request to see or delete what is held about you. The honest answer is usually that there is very little to look up.
A model or provider is missing
New models are added continuously, but the index is not exhaustive. Tell us what is missing and where its published benchmarks and pricing live.
Before you write about a figure
Two things account for most of the mail that turns out not to be an error. The methodology page explains both: cost per task is an estimate computed from list prices against one fixed token profile, and output speed is a median across every provider serving a model rather than the best endpoint available.
An em dash in a table means a figure is missing, not zero. Missing values sink to the bottom of every ranking rather than being counted as nothing.
What we cannot help with
- Support for the models themselves — billing, API keys, rate limits and outages belong to the vendor, not to an index of them.
- Guest post placements, link exchanges and paid inserts. The blog publishes contributed writing, but nothing on this site is for sale.
- Bespoke benchmarking of a private model or a private workload.
