The differentiator

Computed from the stack graph, both directions. Every cited edge links the page it was read from; a vendor-added one links the vendor’s own source — this is the reason to be here rather than on the vendor’s own site.

Configurations

CONFIGURATIONSWhat you can rent, and what it holds

Anthropic publishes no machine-readable catalogue of its instance types, so no configurations are recorded. The prices above were read from its pricing page; a configuration read the same way would be a guess about how many GPUs a price covers, which is the mistake this section exists to avoid.

Frequently asked

How much does Anthropic charge for anthropic/claude-haiku-5.5?
$0.01 per token-1m-in-cached, read from Anthropic's own pricing page on 2026-10-22. 98 rates are listed, each linking to the page it came from.
Does Anthropic offer structured output?
Yes. Read from their own page: “Guarantee schema conformance with two approaches: JSON outputs for structured data responses, and strict tool use for validated tool inputs.”.
How current are Anthropic's prices here?
Every rate on this page was read on 2026-10-22. Nothing older than 21 days is shown: a stale rate is hidden rather than displayed with an old date, and every row links to the page its figure came from.
What does a blank mean on the Anthropic page?
That nobody has told us, not that the answer is no. A hollow ring is "no answer on record", which is a different state from a recorded no — and the two look different on purpose. A blank is an absence of evidence, and this page shows how many of its questions are in that state rather than quietly leaving them out.
Where do the Anthropic figures come from?
Each one is read from a public page — usually the vendor's own documentation or pricing page — and carries a link to it with the date it was read. Nothing here is estimated, averaged across sources, or inferred from a similar product. If a figure cannot be traced to a page, it is not published.
Can Anthropic change what this page says?
They can claim the listing and supply or correct values, which are then labelled as theirs. They cannot remove the page, hide a comparison they are losing, or change a figure somebody else recorded with a source. Nothing on the page is for sale. How the site is paid for is set out under money and independence at /our-data#sec5.
Something here is wrong — how do I fix it?
Dispute the value. Every figure links to the page it was read from, so a dispute names the value and gives a source that contradicts it. That is the only lever anyone has over this page, and it is the same lever for the vendor, a competitor and a reader.
Is this listing run by Anthropic?
No. It is built from public sources, and no value on it came from the company. Anyone with an address at anthropic.com can claim it for free. A claim lets the company write the tagline, description and logo, and answer blank questions or add dependencies, each marked as theirs with a source. Prices, licence and OSS figures stay as the directory read them, category changes only through our review, and each can be disputed with a source.

Cite this page

A model that quotes us should quote us correctly. The reading and its date sit inside the citation rather than beside it, because a quotation carrying only a URL goes wrong the week the URL changes.

What Anthropic can and cannot change here

Claiming Anthropic lets its admins and editors change the tagline, description, logo, docs link and deployment model of every product that org owns — live, labelled as theirs, and logged. Answers to blank questions and dependencies go live too, marked as the owner’s and sourced; a documented answer cannot be overwritten. Everything else on this page is a stated fact with a dispute route: price, licence and OSS figures. Those columns are ungranted at the database level, so they are not a feature we withheld — they are a write that cannot happen. Name, category, website, pricing page and package names can be changed by the owner only through our review. A dispute never deletes a value; it marks it and publishes the correction.
