By training on extensive datasets, these models can acquire a deep understanding of language Patterns and structures, leading to improved performance in various language-related tasks.

The Development and Collaboration Process

4.1 Partnerships and Collaborations

The development of large language models, like the GPT Suite, involves collaborations with various organizations and individuals who share a common interest in advancing research in this field. AI Sweden has formed partnerships with Rice, the Research Arena for Media Language, and Nvidia to develop and train the models. These collaborations allow for shared expertise, access to resources, and collective effort in pushing the boundaries of large language models.

4.2 Resources and Support

The development of large language models requires significant resources and support. AI Sweden has been fortunate to have access to Priscillus, a supercomputer donated by the voluntary foundation, and receive support from Nvidia and the National Supercomputer Center. These resources, along with the expertise of the team members, have played a crucial role in successfully training and optimizing the models.

Data Collection and Preprocessing

5.1 The Nordic Pile Dataset

To train the GPT Suite, AI Sweden collected a diverse dataset known as the Nordic Pile. This dataset includes text data from various sources, including common crawl, forums, governmental agencies, parliamentary debates, and Wikipedia. The dataset consists of approximately 1.5 terabytes of data, with a focus on high-quality, naturally occurring text written by humans for humans.

5.2 Quality Filtering and Duplication Removal

To ensure the quality of the dataset, AI Sweden applied several filters to remove low-quality or automatically generated text. This involved applying quality heuristics to each document, removing duplicate documents, and filtering out similar or repetitive content. The resulting dataset was refined to approximately 1.2 terabytes, ready for model training.

Model Training and Scaling Laws

6.1 Training Process and Framework

AI Sweden utilized the Nemo Megatron framework and the computational resources of Priscillus to train the large language models, specifically the GPT Suite. The training process involved selecting hyperparameters, determining the model size, Dimensions, and parallelism techniques. The models were trained to predict the next word in a given Context, using billions of tokens from the Nordic Pile dataset.

6.2 Utilization and Stability of the Model

Priscillus, the supercomputer used for training, demonstrated stability and high utilization during the training process. The team achieved efficient utilization of the GPUs, allowing for faster training times. The larger the model size, the better the validation performance, indicating the success of the scaling process.

6.3 Scaling Experiments

Alongside model training, AI Sweden conducted scaling experiments to evaluate the relationship between model size, learning rate, batch size, data size, loss, and compute. These scaling laws enabled accurate predictions of model performance and convergence, ensuring optimal training conditions. The experiments also highlighted potential areas for improvement in training strategies and hyperparameters.

Evaluation of the Model

7.1 Validation Projects

To assess the practicality and usefulness of the GPT Suite, AI Sweden initiated validation projects with various partners. These projects involve evaluating the models' performance in specific applications, testing their ability to follow instructions, and refining the output quality. Feedback from these projects will inform further improvements and modifications to the models.

7.2 Qualitative Evaluation

The models' performance was extensively evaluated using qualitative methods. The team noticed the models' proficiency in generating Swedish text, making them the best Swedish language models available. However, challenges were observed in following instructions precisely due to the training methods employed. Zero and few-shot evaluations showed promising results, with larger models outperforming smaller ones.

7.3 Quantitative Evaluation

Quantitative evaluation of the models' performance was conducted using various evaluation techniques. Sierra short evaluations, where the models complete instructions without examples, demonstrated the models' capabilities relative to the OpenAI GPT NeoX model. Ongoing evaluations, including shot models and multi-modality, will provide further insights into the models' performance and potential use cases.

7.4 Shot Models and Multi-Modality

AI Sweden explored shot models, where models respond to instructions with minimal or partial context. Initial evaluations indicate that larger models outperform smaller ones in zero and few-shot scenarios. Multi-modality, incorporating images, sound, and actions into language models, is also an emerging area of interest, with potential applications across various domains.

Developments in the Field

8.1 Evolving Models and Training Paradigms

The field of large language models is continuously evolving, with advancements in model training and complete automation of processes. Training models on trillions of tokens with billions of parameters has shown promise in improving performance.
