OpenAI unveiled its latest large language model (LLM), GPT-4o, on Monday (May 13), promoting it as their fastest and most powerful AI model to date. The company asserts that this new model will make ChatGPT both smarter and more user-friendly. Previously, OpenAI’s most advanced LLM was GPT-4, available only to paid users. In contrast, GPT-4o will be freely accessible to everyone.

GPT-4o: The Omni-Powered Multimodal AI Transforming Human-Computer Interaction

The “o” in GPT-4o stands for “Omni,” highlighting its revolutionary capabilities aimed at enhancing human-computer interactions. Users can input a combination of text, audio, and images and receive responses in these formats, making GPT-4o a true multimodal AI model, a significant advancement over its predecessors. OpenAI’s CTO, Mira Murati, described the new model as a major leap forward in ease of use.

Live demonstrations of GPT-4o reveal it as a digital personal assistant capable of performing a variety of tasks. From real-time translations to reading facial expressions and engaging in spoken conversations, GPT-4o outpaces its competitors. It can interact using text and vision, enabling it to analyze screenshots, photos, documents, or charts and discuss them intelligently.

OpenAI has also enhanced the updated version of ChatGPT with improved memory capabilities, allowing it to learn from previous interactions. LLMs like GPT-4o form the backbone of AI chatbots, utilizing vast amounts of data to self-learn. Unlike earlier models that required multiple systems to handle different tasks, GPT-4o uses a single, end-to-end model trained across text, vision, and audio modalities.

GPT-4o: Revolutionizing AI with Seamless Multimodal Integration and Lightning-Fast Performance

Murati illustrated this by explaining that previous models needed three separate systems for voice mode: transcription, intelligence, and text-to-speech. In contrast, GPT-4o integrates all these functions natively, processing and understanding inputs more holistically. This means GPT-4o can simultaneously interpret tone, background noises, and emotional context in audio inputs, a capability that posed significant challenges for earlier models.

GPT-4o excels in speed and efficiency, responding to queries in approximately 232 to 320 milliseconds, compared to several seconds for previous models. It also features enhanced audio and vision understanding. During a live demo, ChatGPT used GPT-4o to solve a linear equation in real-time from handwritten input, gauge a speaker’s emotions on camera, and identify objects.

This launch comes amidst an intensifying AI race, with tech giants like Meta and Google developing more powerful LLMs. GPT-4o could benefit Microsoft, which has invested heavily in OpenAI, by integrating the model into its existing services. The release also coincides with the Google I/O developer conference, where Google is expected to unveil updates to its multimodal Gemini AI model. Additionally, Apple is anticipated to announce AI advancements at its Worldwide Developers Conference in June.

OpenAI Rolling Out Revolutionary Multimodal AI in Phases with Safety at the Forefront

GPT-4o will be rolled out to the public in phases. Text and image capabilities are already being introduced to ChatGPT, with some services available to free users. Audio and video functionalities will be gradually made available to developers and selected partners, ensuring each modality meets safety standards before full release. Despite its advanced features, GPT-4o is not without limitations. In its official blog, OpenAI acknowledged that GPT-4o is still in the early stages of exploring unified multimodal interaction, with certain features like audio outputs initially limited to preset voices. Further development and updates are needed to fully realize its potential in seamlessly handling complex multimodal tasks.

Regarding safety, OpenAI has built in several measures, including filtered training data and refined post-training model behavior. The company claims that GPT-4o has undergone extensive safety evaluations and external reviews, focusing on risks such as cybersecurity, misinformation, and bias.

As of now, while GPT-40 scores only a Medium-level risk across these areas, OpenAI said that continuous efforts are in place to identify and mitigate emerging risks.
