Researchers have developed SamatNext v0.2-B, a 356M-parameter hybrid sequence decoder designed to mitigate forgetting in small code models during sequential fine-tuning. This experimental model alternates Differential-Attention-style layers with simplified linear-state mixer layers, employing RMS normalization and output scale calibration. In controlled Python code curriculum experiments, SamatNext v0.2-B demonstrated superior retention of earlier training stages compared to a Transformer baseline, achieving a 100.0% pass rate on a later stage while retaining 98.8% of adjacent semantic behavior.
