    The most powerful LLM developed by OpenAI

    The world of AI technology is advancing, and one of the companies pushing it forward is OpenAI. This company has brought several powerful AI models to the market, and one of them is GPT-4o. This is the most capable model from the company, and it's powering some of the company's most useful user-facing features. With advanced reasoning capabilities, GPT-4o is a useful tool for individuals and businesses alike.

    Being much faster than the models that came before it, GPT-4o can generate text at a much better pace. This is useful for when you're using the voice feature. It almost feels like you're having a conversation in real time. Along with that, your responses come in much quicker, which is great for business users.

    The smartest model from OpenAI, GPT-4o has powerful reasoning capabilities. It will be able to answer most of the questions that you can throw at it. You'll get answers that are better written and more natural sounding. This is great for people who are using ChatGPT to craft emails or letters to others.

    Using GPT-4o, you know that you have a powerful tool at your disposal. If you're creating content, running a business, looking for answers, working on projects, etc., the tools powered by GPT-4o can help make life so much easier. 

    Along with the better reasoning capabilities, there's the large 128K context window. With this, you're able to upload a fair amount of content to be digested. If you want to upload an entire novel, you'll be able to do that. It just depends on how long the novel is. This also means that you can upload any image that you have in your gallery to be processed by the model. The future is at your fingertips, and there's no telling where it can take you.

    GPT-4o
    This is the most powerful and most advanced from OpenAI. As such, it's going to be powering all of the company's premier features. Being multimodal, it's able to understand different forms of media like text and images. You gain the most access to this model with a paid ChatGPT plan, but you can also use it in a limited capacity as a free user.
    GPT-4/GPT4-Turbo
    While it's no longer the most powerful model from OpenAI, GPT-4 Turbo still has some serious chops. This model was previously at the forefront of OpenAI's artificial intelligence. It's still multimodal, and it still has the impressive 128k-token context window. It's just not as cheap as GPT-4o, as inputs and outputs cost a fair bit more.
    GPT-4o mini
    This is the least powerful of the models, but it still brings some impressive AI prowess. GPT-4o mini powers ChatGPT for free users, and it's a stripped-down version of GPT-4o proper. It's more powerful than GPT-3.5/Turbo, and that's saying a lot, as that model was the one that brought everyone onto ChatGPT. Users have some powerful AI at their fingertips.
