OpenAI’s GPT-4o: A New Era of Natural Human-Machine Interaction

This past week, OpenAi presented its Spring Update, with Mira Murati acting as event main host. Murati is the Chief Technology Officer (CTO) at OpenAI and is responsible for overseeing technology and research developments at the company.

Also participating were  Mark Chen,  principal investigator who demonstrated voice and vision capabilities through live demonstrations and Barrett Zoph, another of his researchers, participated in hands-on demonstrations and real-time interaction with ChatGPT.

At this event, the launch of GPT-4o, its new flagship model, was presented to the public. GPT-4o represents a significant advance in natural human-computer interaction by enabling the processing and generation of responses from text, audio, images, and videos in real-time.

Main Features of GPT-4o

GPT-4o, where the “o” stands for “omni”, takes multimodal interaction to another level. This model can accept any combination of text, audio, image and video inputs, and generate text, audio and image responses. With response times as fast as 232 milliseconds, GPT-4o comes much closer to the speed of a human conversation.

Advances in Natural Language Processing

GPT-4o not only matches the performance of GPT-4 Turbo in English and code but offers significant improvements in other languages, being faster and 50% cheaper in the API . In addition, the new model significantly reduces multiple language tokenization, facilitating more efficient and accurate understanding. For example, in languages such as Gujarati, the number of tokens has been reduced from 145 to 33, a 4.4-fold improvement.

Improved user experience compared to previous models:

Interaction with GPT-4o is more intuitive, faster, and accessible to a wider audience. Some features:

  • Speed and efficiency: GPT-4o is faster than previous models, improving the user experience by reducing waiting time during interactions.
  • Expanded availability: Unlike previous models, GPT-4o offers its advanced capabilities to free users, democratizing access to artificial intelligence.
  • User interface (UI) enhancements:: The UI has been revamped to make interaction more natural and frictionless, allowing users to focus on collaboration rather than technology.
  • Native speech mode: GPT-4o integrates transcription, intelligence, and text-to-speech conversion natively, eliminating latency and improving communication fluency.
  • Data viewing and analysis capabilities:: It is now possible to upload images and documents for analysis and conversation, and real-time data analysis capabilities have been enhanced, providing a richer and more useful experience.
Specific examples of the use of vision and data analysis

The new model can facilitate both visual understanding of complex problems and real-time data analysis, integrating into workflows and assisting users in academic, professional, and everyday tasks. Some features:

1- Using Vision in ChatGPT

  • Mathematical problem solving:: An example shown was the use of vision ability to solve a linear equation. A user wrote an equation on a piece of paper and showed it to ChatGPT. The model identified the equation and provided step-by-step hints to solve it.
  • Image and document analysis:: Users can upload screenshots, photos, and documents containing both text and images. ChatGPT can analyze this content and engage in conversations about it. This includes the ability to interpret graphs and image annotations.

2. Advanced Data Analysis:

  • Chart generation and analysis:: In the demonstration, it was shown how ChatGPT can generate graphs from data and analyze them. One example was the creation of a temperature graph from weather data, where ChatGPT depicted significant trends and events, such as a large rainfall in September.
  • Use of custom functions: How a custom function can smooth temperature data by applying a moving average was exemplified. ChatGPT explained how this function affects the data and how it is displayed in the resulting graph.
Implementation of new voice and vision capabilities in practical applications:

GPT-4o is a powerful and versatile tool, capable of integrating into a variety of practical applications, improving efficiency and accessibility in multiple sectors. Some examples:

1. Voice Capabilities:

  • Conversational Interaction:  The integration of voice capabilities allows GPT-4o to participate in natural conversations. An example in the video shows how a user can talk directly to ChatGPT, receive verbal responses and continue the conversation without interruption.
  • Real-Time Assistance:  In practical applications, this can be useful for personal digital assistants, where users can dictate commands, ask questions and receive answers without typing. This improves accessibility for people with disabilities and optimizes efficiency in environments where hands are busy, such as in kitchens or workshops.

2. Vision Capabilities:

  • Image and Document Analysis: Users can upload images of documents, graphics or even everyday scenes. GPT-4o can analyze these images, extract relevant information, and provide useful summaries or interpretations. For example, a healthcare professional could upload an image of an X-ray to receive a preliminary interpretation from ChatGPT.
  • Visual Problem Solving: The video shows how a user can upload an image of a handwritten math problem, and GPT-4o can interpret the image, identify the equation, and provide a step-by-step guide to solve it. This is especially useful in educational contexts, where students may need help with complex problems presented in non-digital formats.

3. Real World Applications::

  • Improved Customer Service:  Companies can use GPT-4o to improve customer interaction through chatbots that understand and respond to verbal and visual queries. This may include interpreting screenshots of errors or technical problems and providing immediate solutions.
  •  Process Automation: Vision and data analysis capabilities make it possible to automate complex processes that previously required human intervention. For example, in the field of logistics, GPT-4o can analyze inventory images and generate automatic reports on the status of products.

Other features presented were the availability of its desktop version, also for iPad, in which it will be possible to invoke the AI to help us in our day-to-day tasks with different applications, thanks to its ability to “see” what we are doing. I leave you with a fascinating video about a spectacular use case related to education.

Two highly advanced conversational models GPT-4o and PI from Inflection AI

OpenAI’s GPT-4o and Inflection AI’s PI aretwo advanced artificial intelligence models that have transformed voice interaction. GPT-4o stands out for its multimodal capability, which includes text, audio, image, and video. It offers ultra-fast responses and advanced tone and background noise interpretation, ideal for real-time applications such as virtual assistants and automated customer services. In contrast, PI focuses on personalization and empathy, supporting voice interactions on platforms such as WhatsApp and Messenger, and is especially useful for emotional support and personal coaching applications, thanks to its ability to adapt to the user’s emotions and needs.

Exciting, isn’t it? And we are only at the beginning of this film…
