Australian lab Maincode releases Qwen3-stitched Matilda Platypus base models
ThePrimeClock · reddit · 2026-11-10
Australia's Maincode released the Matilda Platypus family (1.5B–13B base models) built by stitching lower layers of a larger Qwen3 model to upper layers of a smaller one via a learned linear Representation Bridge. The 13B member has 13.51B parameters at 26.3 GFLOP/token, 91% of the larger parent's compute. Early tests look promising.
