About
The Orca family of large language models (LLMs), developed by Microsoft, emphasizes enhancing reasoning capabilities in smaller models. The original Orca model showcased impressive reasoning by emulating the step-by-step processes of more advanced LLMs 2. Orca 2, the latest version, builds upon this foundation, outperforming similar-sized models and rivaling the performance of much larger models on complex reasoning tasks 23. Both models are available for research, with Orca 2 particularly noted for its diverse reasoning techniques and adaptability to different tasks, demonstrating the potential of strategic training to enhance the capabilities of smaller LLMs 2.
