Frequently Asked Questions

  1. Is llama 2 70B better than GPT 4?

LLaMA 2 70B and GPT-4 share a similar level of factual accuracy when it comes to summarization tasks. However, it's important to note that there is a noticeable difference in performance between LLaMA 2 70B and the formidable GPT-4, particularly in specialized tasks such as the HumanEval coding benchmark.

2. Is llama 2-70b better than OpenAI gpt-3.5-Turbo?

Llama-2-70b is almost as strong at factuality as gpt-4, and considerably better than gpt-3.5-turbo. Llama-2-70b is a very good language model at creating text that is true and accurate. It is almost as good as GPT-4, and much better than GPT-3.5-turbo. This is because Llama-2-70b is trained on a massive dataset of factual information, and it uses a variety of techniques to check the accuracy of its output. Llama-2-70b is also open source and more cost-effective than GPT-4 and GPT-3.5-turbo.

3. Should I use llama 2 or deberta?

The choice depends on your specific needs. If your primary task is pure classification, you might want to consider smaller encoder-only models like DeBERTa. These models can offer better performance while having a smaller model size, which can result in more cost-effective inference. However, if you require text generation capabilities and are comfortable with a model with over 7 billion parameters, I would highly recommend Llama 2 or one of its related models.

4. How many parameters does llama 2 have?

Llama 2 is currently offered in three different parameter sizes: 7 billion, 13 billion, and 70 billion parameters. It is available in both pretrained and fine-tuned versions. Meta also developed a 34 billion parameter version, but its release has been postponed.
