Historical direct-API rates recorded for Pareto 26.9: $2.50 input, $0.25 cached input, and $7.50 output per million tokens. The mutable pareto alias now serves Pareto 26.10 Preview; Unbiased does not document a pinned 26.9 endpoint. These preserved rates do not establish that 26.9 remains purchasable. A token estimate is not a measured bill. No direct-API context limit was published for this snapshot.
