About Koala

The Berkeley Artificial Intelligence Research Blog introduces Koala, a dialogue model for academic research.

Here are four key features of Koala

  1. Fine-Tuned Training: Koala is a chatbot trained by fine-tuning Meta’s LLaMA on dialogue data gathered from the web. This process includes the curation of a dataset and a user study comparing Koala to other models like ChatGPT and Stanford’s Alpaca.
  2. Effective Responses: The model can effectively respond to a variety of user queries, generating responses that are often preferred over other models. It suggests that smaller models can capture much of the performance of larger models if trained on carefully sourced data.
  3. High-Quality Datasets: The Koala model emphasizes the importance of curating high-quality datasets. It suggests that this approach might do more to enable safer, more factual, and more capable models than simply increasing the size of existing systems.
  4. Research Prototype: Koala is a research prototype and is not intended for use outside of research due to its shortcomings in terms of content, safety, and reliability. However, its release is expected to provide a valuable community resource.
