TransNormerLLM3 -- A Faster and Better LLM

Introduction

This official repository unveils the TransNormerLLM3 model along with its open-source weights for every 50 billion tokens processed during pre-training.

TransNormerLLM evolving from TransNormer, standing out as the first LLM within the linear transformer architecture. Additionally, it distinguishes itself by being the first non-Transformer LLM to exceed both traditional Transformer and other efficient Transformer models (such as, RetNet and Mamba) in terms of speed and performance.

TransNormerLLM3

TransNormerLLM3-15B features 14.83 billion parameters. It is structured with 42 layers, includes 40 attention heads, and has a total embedding size of 5120.
TransNormerLLM3-15B is purely intergrated with Lightning Attention-2, which can maintain a stable TGS during training of unlimited sequence lengths, up until encountering firm limitations like GPU memory constraints.
Titoken tokenizer is used with a total vocabulary size of about 100,000.
It incorporates Simple GLU for its channel mixer, GLA in the token mixer, and SRMSNorm for normalization.
In terms of position encoding, the first layer employs LRPE with exponential decay, whereas the subsequent layers continue with exponential decay encoding.
