Koala: A Dialogue Model for Academic Research
Koala: A Dialogue Model for Academic Research Introduction The accidental leak of the weights associated with Meta AI’s LLM LLaMA has sparked tremendous innovation in the open-source LLM space. Since the furious leak, we have seen models like Alpaca, Vicuna, ChatLlama, and several others expand on the foundations of LLaMA to build innovative conversational agents that match the capabilities of ChatGPT.

The core goal of Koala is to highlight the balance between mega-large closed-source LLMs and smaller, open-source LLMs. BAIR’s thesis is that smaller models can achieve performance that matches mega models like ChatGPT with a fraction of the cost while also improving in areas such as fine-tuning, transparency, and many others. Koala Koala is a version of LLaMA fine-tu...
