About
Orca 2 13B, developed by Microsoft, is a large language model designed primarily for research purposes. It is a fine-tuned version of the LLaMA-2 base model, focusing on enhanced reasoning capabilities in smaller language models. This is achieved through training on a synthetic dataset specifically created to improve reasoning skills. Orca 2 13B excels in tasks such as reading comprehension, math problem-solving, and text summarization. However, it is not optimized for chat applications and requires fine-tuning for specific tasks.
