The image you sent me shows a comparison of LLAMA 2 Meta with three other large language models (LLMs): MPT, Falcon, and MMLU. The table shows the performance of each model on a variety of benchmarks, such as Natural Questions, Bool, and Winogrande.

As you can see, LLAMA 2 Meta performs significantly better than the other models on most of the benchmarks. This is likely due to the fact that LLAMA 2 Meta was trained on a larger dataset of text and code than the other models.

Here is a more detailed comparison of each model with LLAMA 2 Meta:

  • MPT: MPT is a LLM developed by Google AI. It has 137 billion parameters and was trained on a dataset of text and code from the web. MPT performs well on most benchmarks, but it is not as good as LLAMA 2 Meta on the Natural Questions benchmark.
  • Falcon: Falcon is a LLM developed by OpenAI. It has 175 billion parameters and was trained on a dataset of text and code from the web. Falcon performs well on most benchmarks, but it is not as good as LLAMA 2 Meta on the Bool and Winogrande benchmarks.
  • MMLU: MMLU is a LLM developed by Facebook AI. It has 178 billion parameters and was trained on a dataset of text and code from the web. MMLU performs well on most benchmarks, but it is not as good as LLAMA 2 Meta on the Natural Questions benchmark.
