GPT 4o vs GPT 4

Main differences between GPT 4o and GPT 4


Multimodal Capabilities

GPT 4 is a large multimodal language model that can handle text and image inputs. This allows it to understand and generate text descriptions related to images.GPT 4o builds on GPT 4 by adding audio-video input processing capabilities, making it a more comprehensive multimodal model. This means GPT 4o can not only handle text and images but also understand and respond to audio-video inputs, providing a richer interaction experience.

Response Time and Interactivity

GPT 4's response time and interactivity are not as advanced as GPT 4o's, especially in terms of audio input and output. In GPT 4, audio is first converted to text sent to the GPT, which then returns text converted back into speech, resulting in a few seconds of delay.GPT 4o emphasizes fast response times and advanced interactivity, allowing users to have smoother and real-time conversations. The audio conversation is directly with ChatGPT without converting to text, so it's very fast, responding to audio inputs within 232 milliseconds.

Emotion Recognition and Output

In GPT 4, the conversation is essentially text-based, then converted to speech, so it cannot recognize user emotions and cannot express emotions based on the scene.GPT 4o, trained with audio, can directly sense user tone, emotions, etc., and can express laughter, singing, and other emotional content based on the scene, just like a real person.

Accessibility and Cost

GPT 4 was initially offered through OpenAI's API and specific subscription services, like ChatGPT Plus and Bing search engine, making it inaccessible to regular users.OpenAI announced that GPT 4o will be freely available to all users, including ChatGPT Plus members and regular users. Additionally, the API's speed has doubled, the price is halved, and the number of calls has increased fivefold.

Application Scenarios

GPT 4 is suitable for scenarios requiring processing large amounts of text and image data, such as content creation, data analysis, and complex query handling.Due to the added audio-video processing capabilities and improved interactivity, GPT 4o is particularly suitable for applications requiring voice interaction, such as real-time translation, virtual assistants, real-time customer service, and multimodal educational tools.

About OpenAI GPT 4o

Learn some basic information about the OpenAI GPT 4o model

GPT 4o is OpenAI's latest, most advanced large multimodal language model, significantly improved and expanded upon the original GPT 4. Not only does GPT 4o inherit the abilities of GPT 4 to process text and images, but it also includes new capabilities for recognizing audio inputs, making it a more comprehensive multimodal AI model. Key features include faster response times and more advanced multimodal processing capabilities. GPT 4o can instantly recognize and analyze audio, images, and text information provided by users through the chat interface, offering a richer and more interactive user experience.
GPT 4o is not only free to use but also features capabilities across listening, seeing, and speaking, seamlessly and without delay, like making a video call. It can feel your breathing rhythm and respond in real-time with richer tones than ever before, and can even interrupt conversations.
The 'o' in GPT 4o stands for 'Omni', meaning 'all-powerful'. It accepts any combination of text, audio, and image inputs, and generates text, audio, and image outputs. Researcher William Fedus revealed that GPT 4o was one of the models tested in the big model arena with an unmatched ELO score under the alias 'im-also-a-good-gpt2-chatbot'.
