Questions this tool answers

Can this pricing tracker replace the official Claude pricing page?

No. It is an archive and estimator. Current budget decisions should verify rates against the linked official pricing docs.

Does the estimate include prompt caching, data residency, tool-use, or fast-mode modifiers?

It can optionally apply the base 50% Batch API discount, but it does not include prompt caching, data residency, tool-use, or fast-mode modifiers.

Why is Sonnet 5 listed twice?

The two rows are two dated events at the same price. Sonnet 5 launched June 30, 2026 at $2/$10 described as introductory through August 31, and on September 1, 2026 that rate became the standard rate instead of rising to $3/$15.

Does this tool show current prices?

It shows dated price points verified September 19, 2026. For current pricing analysis see claudereports.com, and verify live rates on the official Claude pricing page.
