Is Claude 3 Better than GPT-4?

In the Anthropic article, Claude claims that the 3 Opus model outperforms the GPT-4 model. Although this is a true claim according to the benchmarks, it should not be forgotten that it is compared with the default GPT-4 model, not the GPT-4 Turbo model.

What is GPT-4?

GPT-4 is an advanced large language model developed and published by OpenAI. GPT-4 large language model is designed to assist users in a wide range of tasks, from tasks such as text generation, paraphrasing, and research to tasks such as ad copy, social media caption generation and code writing. GPT-4 generates new, unique, and human-like responses by analysing user input with its trained data, web search feature and parameters.

GPT-4 Capabilities

OpenAI's GPT-4 large language model can analyse text, code, visual and audio inputs and generate output by understanding them. This makes GPT-4 an effective tool for analysing documents that include graphs, charts, and images such as PPTXs and PDFs.

The GPT-4 model can generate human-like and concise output to user queries using AI technologies such as natural language processing, machine learning, deep learning, neural networks, and parameters. In other words, you can produce various outputs, from email to code. Additionally, the GPT-4 model can generate output in 25+ languages.

What Can You Generate with GPT-4?

You can generate any written content using the GPT-4 large language model. Some of the most popular content you can generate with GPT-4 are:

• Emails

• Paragraphs

• Essays

• Blog Posts

• Research Papers

• Outlines

• Summaries

• Website Copy

• Product Descriptions

and much more. All you need to generate all this is to enter a prompt to GPT-4.

How to access GPT-4?

Although OpenAI offers free access to the GPT-3.5 model to everyone, to access the GPT-4 model you need to purchase an OpenAI Plus subscription, which costs $20 per month. When you get a Plus subscription, you can access OpenAI's GPT-4 large language model and its advanced features such as custom GPTs, web search and more.

Claude 3 vs GPT-4: Performance Comparison

Anthropic's Claude 3 and OpenAI's GPT-4 are both powerful language models that have been making waves in the world of AI. Let's compare these two large language models and discover their similarities and differences.


While introducing the Claude 3 Opus model, Anthropic said that it had higher benchmark scores than GPT-4. While this information is correct for the original public GPT-4 model, it is not valid for GPT-4 Turbo models. For example, according to Anthropic's report, the Claude 3 Opus model has a score of 95.0% in the GSM8K benchmark, while the GPT-4 model has a score of 92.0%. However, in the same GSM8K test, the GPT-4 Turbo model has a score of 95.3%. If we compare the Claude 3 Opus model with the default GPT-4, it is possible to say that Claude 3 Opus has higher performance. However, if we add the GPT-4 Turbo model to the equation, we can say that the Claude 3 Opus model is behind in terms of performance compared to the GPT-4 Turbo.

Input/Output Variety

The Claude 3 model can analyse textual and visual inputs, extract insights from images, read graphs and charts, and generate output by processing them. Additionally, the Claude 3 Sonnet model allows you to upload 5 documents, each up to a maximum of 10MB. If there is a chart or visual in the documents you upload, it can analyse it and give a response. However, the Claude 3 model is only capable of generating textual output.

On the other hand, the GPT-4 model can analyse document, textual, visual, and audio inputs and produce accurate output using this information. Moreover, the GPT-4V model can generate new and unique images by analysing your textual or visual inputs. If you have a job where you need to produce images, GPT-4 will be a better choice than Claude 3.

Prompt Following

Large language models generate output based on user prompts. The better a model is at understanding and following prompts, the more useful it is for the user. The Claude 3 Opus model has more advanced prompt following skills than GPT-4. It can generate 10 logical outputs by following a given prompt, while GPT-4 can only generate 9. In comparison, the Clause 3 Sonnet model was only able to generate 7 logical sentences in the same test. Therefore, GPT-4 can follow prompts better than Claude 3 Sonnet, while Claude 3 Opus can follow prompts better than GPT-4.
