Llama 3 vs. Orca

Overview

Llama 3 is Meta AI's open source LLM available for both research and commercial use cases (assuming you have less than 700 million monthly active users).

The successor to Llama 2, Llama 3 demonstrates state-of-the-art performance on benchmarks and is, according to Meta, the "best open source models of their class, period". Improvements to the pretraining -- 7X more data than Llama 2 --- and post-training -- careful curation of instruction-tuning data -- processes result in improved alignment and output quality

Overview

Orca is a descendant of LLaMA developed by Microsoft with finetuning on explanation traces obtained from GPT-4.

Orca-13B is a LLM developed by Microsoft. It is based on LLaMA with finetuning on complex explanation traces obtained from GPT-4. By using rich signals, Orca surpasses the performance of models such as Vicuna-13B on complex tasks. However, given its model backbone and the data used for its finetuning, Orca is under noncommercial use.
