What is the Difference Between ChatGPT-4 vs. ChatGPT-4o?

Both ChatGPT-4 and ChatGPT-4o are advanced AI models developed by OpenAI. ChatGPT-4 excels in text generation and understanding, with some image processing capabilities. ChatGPT-4o, launched in May 2024, significantly enhances these capabilities by integrating text, image, voice, and video inputs into a single model, allowing for more efficient and versatile applications. Here are the key differences:

Input Types

• ChatGPT-4: Primarily handles text inputs with some image processing capabilities
• ChatGPT-4o: Supports video and voice inputs in addition to text and images, making it more versatile for various applications

Performance

• Speed: ChatGPT-4o is significantly faster, generating responses in milliseconds, which means it can provide near-instantaneous replies to user queries, compared to ChatGPT-4's text-only processing
• Accuracy: ChatGPT-4o provides more precise, detailed, and efficient responses, which can generate more accurate and detailed text with fewer errors, particularly for complex topics and creative tasks

Cost

• ChatGPT-4: Standard pricing
• ChatGPT-4o: Reportedly half the price of ChatGPT-4's Turbo version for similar performance on text tasks. The 'Turbo' version of ChatGPT-4 refers to a high-performance variant with enhanced capabilities, that is priced higher than the standard version

Language Support

• Both ChatGPT-4 and ChatGPT-4o offer support for over 50 languages

Capabilities

• ChatGPT-4: Excels in text generation and understanding
• ChatGPT-4o: Integrates multimodal inputs for a comprehensive and interactive user experience, supporting text, images, voice, and video

Key Features of ChatGPT-4o

ChatGPT-4o (“o” for “omni”) is the most advanced model. It is multimodal (accepting text, image, and video inputs), and it has the same high intelligence as GPT-4 Turbo but is much more efficient—it generates text 2x faster and is 50% cheaper. This efficiency not only saves time but also reduces costs, making it a practical and valuable tool for a broader range of applications. Additionally, ChatGPT-4o has the best vision and performance across non-English languages of any of our models. ChatGPT-4o is available in the OpenAI API for paying customers.

Conclusion

ChatGPT-4o represents a significant evolution in AI capabilities, building on the foundation laid by ChatGPT-4. Its support for multimodal inputs, faster response times, and cost efficiency make it a powerful tool for a broader range of applications. Understanding these differences can help users select the suitable model for their specific needs, whether they require advanced text processing or the ability to handle diverse input types.
