Claude 3.5 Sonnet Pricing
Although the Claude 3.5 Sonnet is freely available through Claude.ai, to use it unlimitedly you must have a Claude Pro subscription, which costs $20 per month. If you want to use the Claude 3.5 Sonnet model as an API, you must pay $3 per million tokens input and $15 per million tokens output.

What is ChatGPT-4o?
ChatGPT-4o model is a Large Language Model developed by OpenAI that can work twice as fast as its predecessor, the GPT-4T model. The GPT-4o model was made public by OpenAI on May 13, 2024. Moreover, since the GPT-4o model has an output generation speed of around 300ms, it can generate output at almost the speed of human speech. Moreover, GPT-4o can generate output by analysing not only textual but also visual inputs.
How Does GPT-4o Work?
The GPT-4o model has been trained by OpenAI with publicly available online data up to October 2023. The GPT-4o model uses its parameters and trained data to analyse the inputs entered by the user and generate concise output. Since the GPT-4o model can also analyse visual input, it can understand documents containing data containing charts and diagrams.
How to Access GPT-4o?
You can access the GPT-4o model with OpenAI's ChatGPT. If you are using ChatGPT in the default model, you have limited access to the GPT-4o model. If you want to experience it unlimitedly, you need to purchase ChatGPT's Plus or higher subscription.

If you want to use GPT-4o in a more interactive and customizable way, you can try ZenoChat developed by TextCortex. ZenoChat is a conversational AI assistant that allows you to use a wide range of LLMs, including GPT-4o.
GPT-4o Pricing
Although the GPT-4o model is available free of charge through ChatGPT, to use it at its full capacity, you need to purchase the ChatGPT Plus subscription, which costs $20 per month. If you want to use the GPT-4o model as an API, you must pay $5 per million tokens input and $15 per million tokens output.

Anthropic’s Claude 3.5 Sonnet vs. OpenAI’s GPT-4o Comparison
Now that we've reviewed Anthropic's Claude 3.5 Sonnet model and OpenAI's GPT-4o model, we can move on to comparing them and exploring the similarities and differences between them. Although both LLMs are at the cutting edge of today's AI technology, they have slight differences. Let's compare two large language models together!
Performance
According to Anthropic's article, the Claude 3.5 Sonnet model outperforms the GPT-4o model in most text-based AI benchmarks. The GPT-4o model outperforms the Claude 3.5 Sonnet model in the MMLU benchmark, which is an undergraduate-level knowledge benchmark, and the MATH benchmark, an arithmetic problem-solving benchmark. In other words, the GPT-4o model is more successful in natural language and mathematics tasks, while Claude 3.5 Sonnet is more successful in reasoning and coding tasks.

Vision Performance
When it comes to vision understanding the performance of Claude 3.5 Sonnet and GPT-4o both models have their own advantages. According to Anthropic's article, the Claude 3.5 Sonnet model has a higher score than the GPT-4o model in MathVista, AI2D, Chart Q&A, and Document visual Q&A benchmarks. The GPT-4o model outperforms the Claude 3.5 Sonnet model in the MMMU benchmark, which is the visual question-answering test.

Context Window
Claude 3.5 Sonnet, the newest member of the Claude LLM family, which has always stood out with its large context window, offers its users a 200K tokens context window. This value is approximately equal to 500 pages or 150,000 words. On the other hand, the GPT-4o model offers its users a 128K tokens context window. This value equals approximately 90,000 words or 300 pages. However, the GPT-4o model can only generate an output of 4096 tokens.
