Key Microsoft AI Orca Facts


Orca is a 13-billion parameter model developed by Microsoft that learns complex explanation traces and step-by-step thought processes from GPT-41. This innovative approach significantly improves the performance of existing instruction-tuned models, addressing challenges related to task diversity, query complexity, and data scaling1.

The researchers acknowledge that the query and response pairs from GPT-4 can provide valuable guidance for student models. Therefore, they enhance these pairs by adding detailed responses that offer a better understanding of the reasoning process employed by the teachers when generating their responses1. By incorporating these explanation traces, Orca equips student models with improved reasoning and comprehension skills, effectively bridging the gap between teachers and students1.

The research team utilizes the Flan 2022 Collection to further enhance Orca’s learning process. The unit samples tasks from this extensive collection to ensure diverse challenges. These tasks are then sub-sampled to generate complex prompts, which serve as queries for LFMs. This approach creates a varied and rich training set that facilitates robust learning for the Orca, enabling it to handle many tasks effectively1.

The researchers conduct comprehensive evaluations to assess Orca’s capabilities, focusing on generative, reasoning, and comprehension abilities. They compare Orca’s performance against strong baselines such as Text-Davinci-003, ChatGPT, GPT-4, and Vicuna. The results demonstrate Orca’s superiority over state-of-the-art instruction-tuned models like Vicuna-13B, showing an improvement of over 100% on BigBench Hard (BBH). Furthermore, Orca exhibits competitive performance on academic exams in zero-shot settings, indicating its potential for real-world applications1.

The research findings confirm the tremendous potential of learning from step-by-step explanations in enhancing model performance. By incorporating detailed explanation traces and scaling tasks with complex prompts, Orca achieves significant advancements in instruction-tuned models. This approach not only empowers student models to enhance their reasoning and comprehension abilities but also enables them to surpass existing benchmarks1.
