Understanding ChatGPT-4o Features Upgrade



  • ChatGPT-4o enhances natural language processing, making it excel in writing assistance and translation.
  • The model offers real-time synchronous translation in 50 languages with near-zero delay.
  • ChatGPT-4o includes visual recognition to assist visually impaired users and can participate in online meetings.


ChatGPT-4o by OpenAI integrates text, audio, and video capabilities. Available in free and paid versions, it offers advanced features like real-time translation and visual recognition.




  • Understand What ChatGPT Is First


ChatGPT is a dialogue system developed by OpenAI based on the GPT architecture. Users only need to input questions, and the AI will make judgments and generate corresponding replies.


GPT (Generative Pre-trained Transformer) is a deep learning architecture that uses the Transformer model to process and generate natural language. Its origins can be traced back to the initial GPT model released by OpenAI in 2018.


This model learns language structure and knowledge through a large pre-trained dataset, such as web articles, books, and conversation records, using unsupervised learning and self-attention mechanisms to capture contextual information and generate responses.


  • The evolution of ChatGPT: ChatGPT-4o


ChatGPT-4o is a significant breakthrough by OpenAI, with the “o” standing for “omni.” ChatGPT-4o is no longer limited to text but integrates reasoning capabilities for audio, video, and text, making it a truly versatile model.


Compared to GPT-4 Turbo:


  1. Processing Capability: 

Excels in handling text, video, and audio, with significant improvements in understanding text and images, and integrates voice functionality.


  1. Multilingual Support:

Familiar with 50 languages, providing real-time interpretation for a more natural communication experience.


  1. Visual Reasoning:

Can read user expressions and tone, providing responses closer to human interactions, and quickly switching between different tones.


  1. Functional Applications:

Powerful visual reasoning capabilities to help visually impaired individuals recognize their surroundings and guide them in hailing a taxi.


  1. Performance Improvement:

Faster API speed, with costs reduced by 50%, nearly instantaneous response, and twice the speed of GPT-4.


  1. More Human-like:

Understands user expressions and tone, interacts more naturally, and adjusts tone during expression.


  1. More Intuitive Use:

No longer requires manual input of commands, directly interacting through conversation or demonstrations, and integrates multiple functions into the same model.

  1. Enhanced Natural Language Processing Abilities


ChatGPT-4o boasts superior language understanding and generation capabilities, able to handle more complex sentence structures and semantics. This makes it excel in writing assistance, content generation, and language translation, allowing it to better understand context and produce responses that align more closely with user instructions.


  1. Faster Response Time


Compared to GPT-4, ChatGPT-4o has significantly improved processing speed. It can respond to questions in as little as 232 milliseconds (0.232 seconds) and averages 320 milliseconds (0.32 seconds).


For comparison, the average response times for GPT-3.5 and GPT-4’s voice mode are 2.8 seconds and 5.4 seconds, respectively. This speed enhancement makes interactions with GPT-4o feel more like natural conversations with a real person.


  1. Real-time Synchronous Translation


GPT-4o is proficient in up to 50 languages and, with optimized voice response times, can achieve “zero-delay” real-time translation. Besides being fast, its translations are also highly accurate, making cross-language communication effortless. Users can even interrupt ChatGPT-4o while it is responding and ask new questions, to which the AI will adapt and respond accordingly.

  1. Lifelike Voice Generation


In terms of voice capabilities, GPT-4o has made significant technical advancements, generating more natural and fluent speech. According to OpenAI, ChatGPT-4o can “read” user expressions and emotions, providing more vivid and contextually appropriate responses.

It can mimic various voice styles and tones, and even react naturally, such as laughing at a joke, making it almost indistinguishable from a human. OpenAI’s CTO, Mira Murati, stated that this development was inspired by human conversation processes, enhancing the diversity and naturalness of GPT-4o‘s generated speech.

  1. Excellent Visual Recognition Abilities


GPT-4o emphasizes improved visual recognition capabilities, accurately identifying and interpreting both static images and dynamic video footage, including surroundings, objects, and activities.


This feature can assist visually impaired individuals by recognizing their environment and conveying information through voice. For example, GPT-4o can guide a user to Buckingham Palace, tell them which road to take to hail a taxi, and remind them to raise their hand to signal the taxi.


Additionally, GPT-4o can identify and interpret user actions in a video call, suggesting activities like rock-paper-scissors and correctly determining the winner.

  1. AI Assistant for Online Meetings


GPT-4o has the ability to recognize screen content. When using the desktop version of ChatGPT, you can share your screen, and ChatGPT-4o will identify the content and engage in discussions with you.


For instance, it can identify the month with the highest temperature on a graph and provide the correct answer immediately. You can also include ChatGPT-4o in online meetings to act as a host, ask it questions, or request meeting summaries, facilitating smooth meeting processes and enhancing work efficiency.

The release of GPT-4o is both an aid and a potential threat to the education sector. Salman Khan, the founder of Khan Academy, released a video demonstrating GPT-4o guiding students through problem-solving like a tutor.


Parents can specify that AI should not provide the answers directly but instead teach step-by-step, encouraging students to solve problems on their own.


Throughout the process, the AI maintains a supportive attitude, guiding students in the right direction even if they make mistakes, and offering praise when they arrive at the correct answer, acting as a highly considerate teacher.

OpenAI has announced that the new model, ChatGPT-4o, will be available in the free version. However, paid subscribers will have a message limit that is five times higher than that of the free version. The voice services provided by GPT-4o are expected to be released to subscribers in a beta version next month.


OpenAI also mentioned concerns about the potential misuse of the voice functionality, so this feature will not be available to all API users immediately. Instead, it will be provided to select trusted partners over the next few weeks. Further updates on the release of additional features will be announced later.
