The Claude 2 large language model is advanced enough to compete with other popular models. One of the few names that comes to mind when it comes to popular large language models is Meta AI's Llama 2. These two large language models have also been introduced by generating safe output and completing basic tasks. 

In this article, we will compare the Claude 2 and Llama 2 large language models.


  • Anthropic has introduced a new language model called Claude 2 that is advanced enough to compete with other popular models.
  • It can analyse large amounts of data, fix code errors, and generate various types of text-based content in 10+ languages.
  • Llama 2 is better at generating safer output, while Claude 2 is better at code generating.
  • While the Llama 2 model offers free use, the Claude 2 model charges $11.02 for every 1 million tokens.
  • If you are looking for a conversational AI that is more advanced with more customization options (personas, file uploads / knowledge bases) features than both of these models, ZenoChat by TextCortex is designed for you.

What is Claude 2?

Anthropic introduced a new language model, Claude 2, on July 11, 2023. This advanced model serves as a high-performance conversational AI for tasks related to text and code generation. What sets Claude 2 apart is its superior understanding of context, reasoning, and coding skills, marking a significant improvement over its predecessor, Claude 1.3.

How Does Claude 2 Operate?

The Claude 2 large language model is estimated to have over 130 billion parameters. The model is useful for analysing inputs and understanding nuances using these parameters and its trained data. The Claude 2 model has been trained with technologies such as natural language processing and reinforcement learning from human feedback. Additionally, Anthropic's development team presents Claude 2 as constitutional AI. The main reason for this is that Claude 2 generates output according to manually adjusted ethical and legal rules.

Claude 2 Capabilities

The most impressive thing about Claude 2 is its input and output size equivalent to 100k tokens. If you want to analyse hundreds of pages of data in one go, Claude 2 is designed for you. For example, you can enter your whole code into Claude 2 and ask it to fix the errors in your code and even explain them.

The Claude 2 language model is also good at generating text-based output. Using it, you can generate emails, blog posts, essays, articles, stories, poems, product descriptions and much more. The only negative of Claude 2 is that it can generate output in only 10+ languages.

Is Claude 2 free to use?

Anthropic offers its users two different models and pricing plans. The first of these plans is called Claude Instant and charges $1.63 per 1 million tokens. The Claude Instant model is suitable for completing basic tasks and for everyday use. The second plan, Claude 2, is successful in understanding complex inputs and generating detailed output. This plan charges $11.02 per 1 million tokens.

What is Llama 2?

Llama 2 large language model is an AI tool announced by Meta AI with 3 different parameter sizes. Llama 2 is designed to provide users with safe and helpful output. According to Meta AI's test of 4,000 prompts, Llama 2 has managed to beat its competitors in the helpfulness race.

Llama 2 Parameters

Llama 2 large language model was presented to users with 7B, 13B and 70B size models. Meta AI used natural language processing, reinforcement learning from human feedback and reward models to train Llama 2. Its reward models ensure that the output is helpful and non-toxic. Although the 70B model of Llama 2 is better than the GPT-3.5 language model, it is not a competitor to GPT-4.

Llama 2 Features

The Llama 2 large language model promises various tasks from text generation to code generation. However, we recommend that you use the Llama 2 model to complete text-based tasks. Its coding skills are not as strong as Claude 2 or GPT-4. 

Llama 2 large language model is designed to generate safe output. If you need to generate safe content and are looking for the help of an AI tool, Llama 2 is a better option than Claude 2 and GPT-4.

How to Access Llama 2?

Accessing the Llama 2 large language model is a straightforward process. Simply visit its official website and follow the provided instructions. Additionally, the market offers AI chatbots that utilize the Llama 2 model, further expanding its reach and application.

Anthropic’s Claude 2 vs Meta AI’s Llama 2 Comparison

Now that we have a general overview of both the Claude 2 and Llama 2 models, we can compare them. Both models have identical differences and similarities. If you're ready, let's start.

Performance Differences

When it comes to code generation, Claude 2 has a higher performance by far. If you are looking for an AI tool for your coding tasks, Claude 2 outperforms Llama 2. But if you want to complete text-based tasks, Llama 2 will be a good choice according to its safe output capacity.

One of the differences between the two models is their input capacities. Claude 2 offers users an input size of 100k tokens, while Llama 2 offers an input size of 4,000 tokens. If you want to process and analyse more data at once, Claude 2 is the better choice.

Quick Comparison

We have listed the main differences of both language models in the table for you.
