AMD-Llama-135m-code-GGUF

Introduction

AMD-Llama-135m is a language model trained on AMD MI250 GPUs. Based on LLaMA2 model architecture, this model can be smoothly loaded as LlamaForCausalLM with huggingface transformers. Furthermore, we use the same tokenizer as LLaMA2, enabling it to be a draft model of speculative decoding for LLaMA2 and CodeLlama.

Quickstart

AMD-Llama-135m-code-GGUF can be loaded and used via Llama.cpp, here is a program with GUI.

Training and finetuning cost

It takes 6 days to pretrain AMD-Llama-135m on 4 MI250 nodes each of which has 4 MI250 GPUs (8 virtual GPU cards, 64G memory for each). It takes 4 days to finetune AMD-Llama-135m-code on 4 MI250 GPUs. It takes 11T disk space to store raw and processed SlimPajama, project gutenberg and Starcoder datasets.
