OpenAI Unveils GPT-4o: A Faster, Free Model for All ChatGPT Users

May 17, 2024

In a highly anticipated livestream announcement on Monday, OpenAI’s CTO Mira Murati introduced the latest advancement in artificial intelligence technology: GPT-4o. This new iteration of the GPT-4 model, which powers ChatGPT, promises to be significantly faster and more capable across text, vision, and audio. The best part? It will be free for all ChatGPT users.

The Evolution of GPT-4o

Since its inception, OpenAI has been at the forefront of AI innovation. With the launch of GPT-4o, the company continues to push boundaries, offering a model that not only enhances user experience but also democratizes access to advanced AI technology.

Murati emphasized that GPT-4o will be rolled out iteratively, starting with its text and image capabilities. This gradual rollout ensures a smooth transition and allows users to experience the model's full potential step by step. Paid users will still enjoy certain privileges, such as up to five times the capacity limits compared to free users, ensuring that heavy users get the performance they need.

Multimodal Mastery

A standout feature of GPT-4o is its native multimodal capabilities. This means the model can generate content and understand commands across various formats—voice, text, and images. OpenAI CEO Sam Altman highlighted that developers will have access to the GPT-4o API, which is not only twice as fast as the GPT-4 Turbo but also half the price. This makes it an attractive option for developers looking to integrate advanced AI into their applications without breaking the bank.

Enhancements to ChatGPT Voice Mode

One of the most exciting updates is the improvement to ChatGPT’s voice mode. With GPT-4o, the app will function more like a Her-like voice assistant, capable of responding in real-time and observing the world around you. This is a significant upgrade from the current voice mode, which is limited to responding to one prompt at a time based solely on what it can hear. This enhancement opens up new possibilities for interactive and immersive user experiences.

Reflecting on OpenAI's Journey

In a reflective blog post following the livestream, Altman discussed OpenAI’s evolving vision. Initially, the company aimed to create AI that would provide a wide range of benefits to the world. However, over time, this vision has shifted. OpenAI has faced criticism for not open-sourcing its advanced models, and Altman acknowledges that the focus has now turned to making these models available to developers through paid APIs. This approach allows third parties to leverage OpenAI’s technology to create innovative solutions that benefit everyone.

“Instead, it now looks like we’ll create AI and then other people will use it to create all sorts of amazing things that we all benefit from,” Altman wrote, signaling a strategic pivot that aligns with the company’s long-term goals.

Speculations and Expectations

The launch of GPT-4o comes amid a flurry of speculation and excitement. Prior to the announcement, various reports had predicted different potential releases from OpenAI, including an AI search engine to rival Google, a voice assistant integrated into GPT-4, or even a new model, GPT-5. The timing of this launch, just ahead of Google I/O, is strategic, as it sets the stage for OpenAI to showcase its advancements before Google unveils its own AI products from the Gemini team.

What This Means for You

For current and prospective ChatGPT users, the introduction of GPT-4o is a game-changer. Here’s what you can look forward to:

  • Faster Performance: Enjoy quicker response times and smoother interactions.
  • Enhanced Capabilities: Benefit from improved functionalities across text, vision, and audio.
  • Free Access: Experience the power of GPT-4o without any additional cost.
  • Developer-Friendly: Utilize the API for innovative applications at a lower cost with faster processing.


The launch of GPT-4o marks a significant milestone in the evolution of artificial intelligence. OpenAI’s commitment to enhancing its models and making them accessible to a broader audience underscores the transformative potential of AI in our daily lives. As we move forward, the possibilities are endless, and the impact of these advancements will continue to shape the future of technology.

For those interested in exploring the capabilities of GPT-4o, now is the perfect time to dive in. Whether you’re a developer looking to integrate AI into your projects or a user eager to experience the latest in AI technology, GPT-4o offers a wealth of opportunities.
