Llama 2 vs. WizardLM

LLM Comparison


Llama 2

Llama 2

Overview

Llama 2 is Meta AI's open source LLM available both research and commercial use case.


The successor to LLaMA (henceforce "Llama 1"), Llama 2 was trained on 40% more data, has double the context length, and was tuned on a large dataset of human preferences (over 1 million such annotations) to ensure helpfulness and safety. It outperforms other open source models on both natural language understanding datasets as well as in head-to-head face-offs.

WizardLM

WizardLM

Overview

WizardLM is a variant of LLaMA trained with complex instructions.


WizardLM is a LLM based on LLaMA trained using a new method, called Evol-Instruct, on complex instruction data. By using AI to "evolve" instructions, WizardLM outperforms similar LLaMA-based LLMs trained on simpler instruction data. On the 6th of July, 2023, WizardLM V1.1 was released with significantly improved performance.
