Introduction

Luther AI is a research organization dedicated to AI research, specifically in the field of transformers and language models. With a focus on collaboration and making research accessible to all, Luther AI has been able to produce groundbreaking research and gain support from funding institutions.

About Luther AI

Luther AI is a discord Channel that serves as a platform for AI researchers to collaborate and perform research in the field of transformers and language models. With access to GPUs and other resources, Luther AI aims to organize open-source research and make it more accessible and collaborative.

Our Research Community

Luther AI has built a vibrant research community on Discord, where members from academia and various industry groups come together to collaborate and discuss AI research. The community is open to anyone interested in the field, providing a platform for sharing ideas and learning from one another.

Our Mission and Focus

At Luther AI, our mission is to make AI research more accessible, public, and collaborative. We prioritize transparency in research and aim to break away from the proprietary nature often associated with code, models, and data. We believe that open collaboration and public discourse are essential for advancing the field of AI.

Training the 20 Billion Parameter Model

The training of the 20 billion parameter model was an endeavor that stemmed from the idea of replicating the success of GPT-3. The founders of Luther AI, Conor Elechi and Leo Gao, started a Discord server to discuss the training process and collaborate on training a similar model.

The model was trained on 96 A100 GPUs, and Luther AI provided the infrastructure and resources for researchers to work with. The process involved using parallelization techniques, such as data parallelism and pipeline parallelism, to optimize model training.

Understanding Transformers and Language Models

Transformers are a key component of language modeling. They consist of layers that compute Attention and feed-forward operations to process input data. Luther AI's 20 billion parameter model, similar to GPT-3, utilized transformers to generate high-quality language-Based outputs.

Optimizing the Model

The Luther AI team implemented various optimization techniques to enhance the performance of the 20 billion parameter model. This included incorporating rotary positional embeddings, which improved the model's ability to handle position-based tasks. Parallelization techniques, such as model parallelism and tensor parallelism, were also employed to efficiently utilize GPU resources.

Evaluating the Model

The Luther AI team developed a language model evaluation framework called the Language Model Evaluation HarM. This framework enabled them to compare the performance of their 20 billion parameter model with other models, such as the ones released by Meta AI.

The evaluation results showcased the model's superior performance on various language modeling tasks, including a focus on factual information, as Luther AI included datasets related to law, medicine, and mathematics in their training data.

Safety Considerations

Safety is a crucial aspect when working with large language models. Luther AI believes that the best way to ensure safe usage of these models is through open collaboration and access to the models and data. By making these resources available to researchers, Luther AI aims to facilitate research on model safety and ethical applications.

Future Directions

Looking ahead, Luther AI has several exciting future directions. They are developing Pithia, a suite of language models ranging from smaller to larger scales. They are also working on providing access to compute resources for researchers who wish to work with large models. Additionally, Luther AI is eager to conduct scientific research on these models, explore multimodal models, and collaborate with other organizations to further the field of AI research.
