anthropic.com published this account (2026-10-07): Anthropic page dated October 7, 2026 introduces Claude Haiku 5.5 at $0.10/$0.50 per million input/output tokens up to 100k tokens and $0.50/$2.50 above, with cache reads at $0.01/$0.05. Same page says average run cost is about 75% below Haiku 4.5 and that Sonnet 5.5 cache reads fall from $0.20 to $0.10 per million tokens.

This guide uses that public page as the example. This site did not run the test, close the deal, or measure the product.

Write only what the page says

The page's claim is: Anthropic page dated October 7, 2026 introduces Claude Haiku 5.5 at $0.10/$0.50 per million input/output tokens up to 100k tokens and $0.50/$2.50 above, with cache reads at $0.01/$0.05. Same page says average run cost is about 75% below Haiku 4.5 and that Sonnet 5.5 cache reads fall from $0.20 to $0.10 per million tokens.

Put the URL under that sentence. If a later recap adds a number or a date, keep the original page as the record.

One row per name. Leave the result cell empty until you have an action you could fail.

Do the site's check on this one page. Fill a line only when the page supports it. Where the page is silent, write Not stated.

A finished note names the page, the date, and the limit of the claim. It does not borrow a result from a different story.

Stop at the untested line

Anything you did not open, install, or count stays untested. Leave that line visible.
