Silia
A small transformer variant that merges the attention layer with the SwiGLU feed-forward layer to cut parameters at very small model sizes, without losing much performance.
Silia (Silu in Attention) is a neural network architecture that merges the attention layer with the SwiGLU feed-forward layer from the Transformer, aimed at models of about 100 million parameters or fewer, where a standard Transformer is argued to use more parameters than it needs. The paper-style write-up frames this as an under-explored regime: models called small, such as Qwen, Gemma and GPT-OSS, still run from 1 to 20 billion parameters.
Trained on the Fineweb-edu dataset, Silia is reported to reach competitive validation loss and generation quality against other models of equal or greater size, evaluated on the HellaSwag, PIQA and LAMBADA benchmarks.
