Orca 2, a breakthrough in the development of smaller, more efficient LMs!

The realm of artificial intelligence (AI) is constantly evolving, with new advancements emerging at an unprecedented pace. Language models (LMs) have become a cornerstone of AI development, capable of processing and generating human language with remarkable proficiency. However, the computational requirements and storage needs of large LMs pose significant challenges, limiting their widespread adoption.

Orca 2 boldly breaks away from this imitation-centric paradigm by encouraging smaller LMs to employ a range of reasoning techniques, tailoring their approach to the specific demands of each task. This flexibility empowers Orca 2 to tackle complex problems that would overwhelm smaller, imitation-based LMs.

Orca 2 introduces a groundbreaking training framework that guides the model towards a diverse repertoire of reasoning strategies. This includes step-by-step reasoning, where the model meticulously breaks down complex problems into manageable steps; recall and generate, where it retrieves relevant information from memory and generates new solutions; recall-reason-generate, where it combines both recall and reasoning techniques; and direct answer, where it provides concise and accurate solutions when possible.

This comprehensive range of reasoning approaches allows Orca 2 to handle a wide spectrum of tasks with remarkable agility and accuracy. It seamlessly adapts to the nuances of each problem, employing the most effective strategy for the given context.

The effectiveness of Orca 2 is undeniable, as demonstrated by its exceptional performance on a comprehensive set of 15 diverse benchmarks. These benchmarks encompass approximately 100 tasks and over 36,000 unique prompts, covering a wide range of reasoning challenges.

Across these benchmarks, Orca 2 delivers remarkable results, consistently outperforming models of similar size. In some cases, it even surpasses the performance of models that are 5-10x larger, marking a significant breakthrough in the field of smaller LMs.

To further accelerate the advancement of AI research, the weights of Orca 2 have been made publicly available at this [URL] link. This generous gesture will enable researchers worldwide to delve into the intricacies of Orca 2's architecture and explore its potential for various applications.
