​OpenAI has recently unveiled GPT-4o, an advanced model designed to process and understand various forms of input, including text, images, and voice. The “o” in GPT-4o stands for “Omni,” highlighting its comprehensive capabilities. This development signifies a significant leap towards AI systems that can interact more naturally with humans.​

Key Differences Between GPT-4 and GPT-4o

GPT-4o introduces several enhancements over its predecessor, GPT-4:​

• Multimodal Capabilities: Unlike GPT-4, which primarily focuses on text, GPT-4o can process images and voice inputs, enabling it to interpret visual data and engage in voice conversations.
• Enhanced Responsiveness: GPT-4o boasts a response time of approximately 232 milliseconds, comparable to human conversational speed, facilitating more fluid interactions.​
• Improved Efficiency: The model operates twice as fast as GPT-4 Turbo and reduces computational costs by about 50%, making it more accessible and cost-effective.​
• Better Multilingual Support: GPT-4o has improved proficiency in languages other than English, offering faster and more accurate responses in languages like Korean.​

How to Use GPT-4o

To engage in voice conversations with GPT-4o:

1. Install the ChatGPT App: Available on both iOS and Android platforms.​
2. Log In: Use your OpenAI account credentials to access the app.
3. Initiate Voice Interaction: Tap the headphone icon at the bottom of the screen to start a voice conversation.​
4. Engage in Dialogue: Ask your questions verbally, and GPT-4o will respond in kind, allowing for seamless, hands-free interaction.​

Availability and Pricing

As of May 17, GPT-4o is accessible to users subscribed to the paid plan. While OpenAI aims to make GPT-4o available to free users globally, rollout schedules may vary by region.​

Implications of GPT-4o’s Release

Sam Altman, CEO of OpenAI, emphasized two main points regarding GPT-4o:​

1. Accessibility: OpenAI is committed to providing powerful AI tools either for free or at a low cost, ensuring widespread availability without relying on advertisements.​
2. Revolutionizing Human-Computer Interaction: The new voice and video modes offer an intuitive interface, making interactions with computers more natural and human-like than ever before.​

The introduction of GPT-4o represents a pivotal moment in AI development, potentially reshaping how humans interact with technology. As AI continues to evolve, models like GPT-4o bring us closer to seamless, multimodal communication between humans and machines.
