NanoLM-365M-base

English | 简体中文

Introduction

Based on Qwen2-0.5B, the tokenizer has been replaced with BilingualTokenizer-8K to reduce the number of parameters. The total parameters have been reduced from 0.5B to 365M.

Details

To recover some performance and facilitate fine-tuning for downstream tasks, I chose to freeze the backbone parameters and only train the embedding part after replacing the tokenizer. Training was conducted for 40,000 steps on wikipedia-zh and cosmopedia-100k.
