New decoder architecture shows improved retention in small code models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed SamatNext v0.2-B, a 356M-parameter hybrid sequence decoder designed to mitigate forgetting in small code models during curriculum learning. This experimental model alternates Differential-Attention-style layers with simplified linear-state mixer layers, employing RMS normalization and output scale calibration. In controlled tests on a Python code curriculum, SamatNext v0.2-B achieved a 100.0% pass rate on a later stage while retaining 98.8% of earlier stage semantic behavior, significantly outperforming a parameter-matched Transformer baseline in retention.

    SamatNext v0.2-B: An Exploratory Study of RMS-Normalized Hybrid Decoders for Curriculum Retention in Small Code Models

    arXiv:2606.22248v2 Announce Type: replace-cross Abstract: Standard autoregressive Transformer decoders can often exhibit substantial forgetting under sequential fine-tuning on shifting curriculum distributions. This technical report evaluates SamatNext v0.2-B, an experimental 356…
