What Is ChatGPT-4o?

On May 13th, OpenAI officially announced the launch of its latest flagship generative AI model, GPT-4o. The release of this all-in-one model heralds another leap forward in AI technology, bringing unlimited possibilities for future human-computer interaction experiences.

If you subscribe to ChatGPT Plus, you'll be able to see OpenAI's descriptions of the 3 models currently available; GPT 4 is described as an advanced model for complex tasks, while GPT 4o officially holds the title of the newest, most advanced model.

GPT-4o, with "omni" indicating omnipotence, handles any combination of text, audio, and image inputs and outputs, offering the same intelligence as GPT-4 Turbo but twice as fast and half the cost. Compared to the previous version, it converses with the user basically without delay, listens, nags, and is also good at reading people, making it amazing to see that the new version of ChatGPT is only lacking a physical body compared to a human.

In addition, OpenAI has come together with Apple to launch a desktop-level app for macOS. The innovative initiative also enables users to be more flexible and fully integrate ChatGPT with their lives and work to maximize efficiency.

Now, let's take a detailed look at those amazing features of ChatGPT-4o.

The Features of ChatGPT 4o

In traditional benchmarks, the GPT-4o achieves comparable performance to the GPT-4 level in text, inference, and coding, but it is a complete game changer in the AI world with the following three areas.

・Response Time

GPT-4o is able to respond to audio input as fast as 232ms, with an average response time of 320ms, which is almost as close to the response time of a human in a real-life conversation.

It means ChatGPT-4o can respond to questions in real time, no longer with a 2-3s time lag. Meanwhile, users can interrupt the chatbot at any time, without having to wait for it to finish its sentence as before. It can be said that this ability greatly enhances the sense of realism that ChatGPT-4o can bring to a person.

・Real-time Voice

Real-time voice is the biggest highlight of ChatGPT-4o. We can easily see from the OpenAI demonstrated videos that ChatGPT-4o has made significant progress in voice output - it sounds significantly "better at chatting".

ChatGPT-4o can sense human emotions, for example, if the demonstrator is breathing heavily, it will ask the person if he needs to stabilize their mood a bit. During a delay-free chat, ChatGPT-4o can change its tone of voice exactly according to the atmosphere, throw in a few jokes from time to time, use a tone carrying a hint of laughter, and even allow users to generate different styles of voice.

・Vision Functions

The vision function of the ChatGPT-4o has also been fully evolved. It is able to help users solve problems in real time through the device camera, but instead of telling you the exact answer.  GPT 4o really acts like a tutor, giving you some hints at the right time and taking you along with it out of the fog of thinking.

Although the function of ChatGPT-4o is still far from perfect, its release has already brought great shock to people. We can't help but expect - could the plot of the movie Her really be played out in real life?

How Much Is ChatGPT 4o?

Fortunately, ChatGPT-4o is currently free to the public.

OpenAI says that they have always made it their mission to make advanced AI tools available to as many people as possible, and have opened up access to a large number of GPT-4o features for free users, including data analysis, browse, vision, and file uploads.

Free users will use GPT 4o for conversations by default, but the number of messages they can send will be limited. The limit is not specified at the moment, but officials say it will be flexible based on current usage and demand.
