1.      GPT-4o supports text, audio, and image inputs and can respond to the same formats, allowing for a seamless and integrated interaction experience. This multimodal functionality represents a significant advancement, enabling the AI to interpret and process various types of inputs natively and holistically.

2.      The model is capable of responding to queries in 232 to 320 milliseconds, closely mirroring human conversational speed. This rapid response time, combined with its ability to support multiple languages, greatly enhances accessibility and usability, making interactions with GPT-4o both swift and globally inclusive.

3.      GPT-4o includes robust safety features such as filtered training data and refined post-training model behavior. OpenAI has conducted extensive safety evaluations and external reviews to address potential risks like cybersecurity threats, misinformation, and bias, ensuring the model is reliable and safe for users.


OpenAI has announced its latest large language model (LLM), GPT-4o, which is now available for free to users. This new model, unveiled on May 13, represents the most advanced and efficient AI from OpenAI to date. GPT-4o, where the "o" stands for "Omni," is set to revolutionize human-computer interactions by supporting multimodal inputs, allowing users to input text, audio, and images and receive responses in the same formats. This leap in technology aims to make ChatGPT smarter and more user-friendly, enhancing the overall user experience significantly.


A key feature of GPT-4o is its multimodal capability, which marks a substantial improvement over previous models that required multiple models to handle different tasks. With GPT-4o, a single model can process and understand text, vision, and audio inputs natively. This integration allows the AI to interpret tone, background noises, and emotional context in audio inputs holistically. This comprehensive understanding was a significant challenge for earlier models, but GPT-4o manages it seamlessly, providing a more nuanced and efficient interaction.


GPT-4o's speed and efficiency are noteworthy, with the model capable of responding to queries almost as quickly as a human, within 232 to 320 milliseconds. This is a considerable advancement over previous models, which could take several seconds to respond. Additionally, GPT-4o supports multiple languages, improving its handling of non-English texts and making it more accessible globally. Its enhanced audio and vision capabilities were demonstrated during a live event where it solved a linear equation written on paper in real-time and identified emotions and objects on camera.

OpenAI has emphasized the integration of GPT-4o into various platforms, which could benefit partners like Microsoft, which has invested significantly in OpenAI. As the AI race intensifies with competitors like Meta and Google developing their powerful LLMs, GPT-4o’s release is timely. Google's forthcoming Gemini AI model, expected to be multimodal like GPT-4o, highlights the competitive landscape. Announcements from Apple's Worldwide Developers Conference in June are also anticipated, potentially incorporating AI advancements into iPhones and iOS updates.


The rollout of GPT-4o will be gradual, starting with text and image capabilities already being made available on ChatGPT. Audio and video functionalities will be introduced progressively to developers and select partners. This phased approach ensures that each modality meets the necessary safety standards before full release. Despite its advanced features, GPT-4o initially offers limited audio output options with preset voices, indicating ongoing development to fully harness its multimodal potential.


Safety remains a critical focus for OpenAI, with GPT-4o incorporating built-in safety measures, including filtered training data and refined model behavior post-training. Extensive safety evaluations and external reviews have been conducted to address risks such as cybersecurity, misinformation, and bias. While the model currently scores a Medium-level risk in these areas, OpenAI is committed to continuous improvement to identify and mitigate emerging risks, ensuring that GPT-4o remains a safe and reliable tool for users.
