Midfield stalwart Daniel Baier has been given a new one-year deal to extend a contract which was to run another season, while Caiuby, Jeffrey Gouweleeuw and Philipp Max have agreed two-year extensions.
Brazilian striker Caiuby's contract now runs until 2020, while defenders Max and Gouweleeuw have signed until the end of June, 2022.
Augsburg finished 13th in the league season after narrowly escaping the relegation/play-off place.
