GPT-4o: The Next Evolution of OpenAI's Language Models

GPT-4o (the "o" means "omni") is a state-of-the-art multimodal large language model developed by OpenAI and released on May 13, 2024. It builds upon the success of the GPT family of models and introduces several advancements in comprehensively understanding and generating content across different modalities.

GPT-4o offers better natural language processing capabilities and a faster response time compared to previous models. It can natively understand and generate text, images, and audio, enabling more intuitive and interactive user experiences. This allows GPT-4o to have improved abilities to not only answer knowledge-based questions and create text, but also analyze and describe images and videos.

GPT-4o's Capabilities

The new enhancements brought by OpenAI to this model elevate its audio, vision and text capabilities.

Multimodal Input and Output

Each input and output of GPT4-o can be any combination of text, audio and images. Unlike OpenAI's previous models, all text, audio and images are processed without any conversion (GPT-4o can read images, hear audio and output them directly). This offers GPT-4o the ability to process them faster and have better understanding of these items.

Real-Time Natural Conversations

The enhanced voice recognition and response capabilities of GPT-4o's enable it to engage in verbal conversations (even in different languages) without noticeable delays. The model can observe tones and emotions of the speakers and deliver proper responses. It can also speak with a natural voice and with emotional nuances, enabling more sensitive communications.

Visual Content Analysis and Editing

GPT-4o can better understand and edit visual content. It can read the graphics, text or data on images and understand the meanings behind. You can upload images for analysis, gaining more precise insights and explanations. The model can also create or edit images as exactly as your prompt requests with high quality.

Memory and Contextual Awareness

GPT-4's upgraded context window ensures that it can maintain context over longer conversations. It supports up to 128,000 tokens, enabling detailed analysis and coherent conversations.

GPT-4o vs GPT-4 vs GPT-3.5

Want to know how GPT-4o is different from GPT-4 and GPT-3.5? Here are their key differences:


  • GPT-4o was initially released in May 2024.
  • It is a more advanced multimodal model with faster speeds and lower latencies to respond to audio and video inputs.
  • GPT-4o is trained on data up to Oct 2023.
  • GPT-4o is performing better on benchmarks of reasoning, speech recognition, and visual capabilities.
  • It has significant improvement on text processing in non-English languages.


  • GPT-4 was initially released in March 2023.
  • It is a multimodal model, meaning it can understand image and voice inputs along with text prompts.
  • GPT-4 is trained on more up-to-date data, up to Dec 2023.
  • GPT-4 performs better than GPT-3.5 in areas like coding, writing, reasoning, and avoiding disallowed content.
  • GPT-4 is more reliable and creative, and has better scores on benchmarks than GPT-3.5.


  • GPT-3.5 was released in November 2022. It powers the free version of ChatGPT.
  • GPT-3.5 is limited to text input and output.
  • It is trained on older data up to Sep 2021.
  • GPT-3.5 can sometimes be less reliable and creative when generating responses.

How to Access GPT-4o

GPT-4o has been made accessible since its release. There are several ways you can access and experience its power:

Use GPT-4o on ChatGPT

OpenAI has allowed the ChatGPT users to use this new model right on the chatbot. Free users will have access with message restriction and can only interact with this model with text. For the paid ChatGPT Plus users, all these restrictions are lifted.

Use GPT-4o with OpenAI's API

OpenAI has also made GPT-4o available as a model option for API access. Developers are now allowed to integrate the GPT-4o power into their project or application.
