Fugu Max

sakana
Try in playgroundCompare

Fugu Max is the largest tier of Sakana AI's Fugu line — a 1M-token-context model that takes text, images, and files and returns text. It joins sakana/fugu and sakana/fugu-ultra as a distinct tier, and is not a v2 of fugu-ultra (that one is folded into the existing row as an alias, not a new listing).
