Largest context window AI models

Sorted by the context window published for each model in this ledger. The largest published window on the check date is 1.05M tokens. A missing window is n/a and is not treated as zero. A larger window is not a quality ranking. Prices beside the window are the stored rate, and the Rate column keeps off-peak, introductory, legacy, and short-prompt labels visible. Max output is a separate published figure when the source lists one.

Model pages link to the limits source when it is a different page from the price source. The full comparison can sort the same column.
