In the realm of machine learning, large language models (LLMs) have been making significant strides. One such model that has gained attention is Meta AI's LLaMA. However, access to proprietary models like LLaMA can be challenging for researchers. Enter OpenLLaMA, an open-source reproduction of Meta AI's LLaMA, designed to address this very issue.

OpenLLaMA is a permissively licensed model that has been trained with 200 billion tokens, making it a powerful tool in the field of Natural Language Processing (NLP). This article will delve into the details of OpenLLaMA, its comparison with LLaMA, and its potential for commercial use.

OpenLLaMA-13B: The Latest Update of OpenLLaMA

OpenLLaMA continues to evolve, with the latest update being the release of OpenLLaMA-13B. This model aims to serve as an Apache-licensed "drop-in" replacement for Meta's LLaMA models. It has been trained on 1 trillion tokens using the RedPajama dataset. Given the popularity of models based on LLaMA-13B, this new model is expected to be quite useful.

The decision to aim for 100% compatibility with LLaMA is a strategic one. This compatibility allows OpenLLaMA-13B to leverage the existing LLaMA ecosystem, such as llama.cpp. This is a significant advantage, considering that machine learning developers are generally reluctant to adopt new models unless they offer significant improvements.

The OpenLLaMA project has released 3B, 7B, and now 13B models trained on 1 trillion tokens. They provide both PyTorch and JAX weights of pre-trained OpenLLaMA models. This ongoing development and the release of new models underscore the project's commitment to providing accessible and powerful language models for the machine learning community.

What is OpenLLaMA?

OpenLLaMA is an open-source reproduction of the LLaMA model developed by Meta AI. It was created to provide researchers and developers with an accessible and permissively licensed large language model. The creators of OpenLLaMA have released a 7B model that has been trained with 200 billion tokens. This model includes PyTorch and Jax weights of pre-trained OpenLLaMA models, evaluation results, and a comparison against the original LLaMA models.

The OpenLLaMA project is a significant development in machine learning, particularly for those who require large language models but face challenges accessing proprietary models. The creators of OpenLLaMA have made the model publicly available, providing a valuable resource for the machine learning community.

OpenLLaMA vs LLaMA: The Training Process

The creators of OpenLLaMA trained their models on the RedPajama dataset, a reproduction of the LLaMA training dataset containing over 1.2 trillion tokens. They followed the same preprocessing and training hyperparameters as the original LLaMA paper, including model architecture, context length, training steps, learning rate schedule, and optimizer. The only difference between their approach and the original one is the dataset used: OpenLLaMA employs the RedPajama dataset rather than the one utilized by the original LLaMA.

The models were trained on cloud TPU-v4s using EasyLM, a JAX-based training pipeline developed for training and fine-tuning language models. They employed a combination of normal data parallelism and fully sharded data parallelism (also known as ZeRO stage 3) to balance the training throughput and memory usage. Overall, their training run achieved a throughput of over 1900 tokens/second / TPU-v4 chip.

OpenLLaMA Performance: A Comparison with LLaMA

The performance of OpenLLaMA was evaluated on several tasks using the lm-evaluation-harness. The results were compared against the original LLaMA model and GPT-J, a 6B parameter model trained on the Pile dataset by EleutherAI. The evaluation metrics for the original LLaMA model were generated by running it on the same tasks. The results for the LLaMA model slightly differed from those reported in the original LLaMA paper, which may be due to differences in evaluation

metrics. However, OpenLLaMA showed competitive performance, demonstrating its potential as an open-source alternative to LLaMA.
