OpenAI Launches Lightning-Fast GPT-4o Model as New ChatGPT Default Starting April 30

OpenAI has officially launched its groundbreaking GPT-4o model, a revolutionary leap forward in the world of artificial intelligence that is set to become the default engine for ChatGPT starting April 30, 2025. The GPT-4o model, with the “o” representing “omni,” introduces lightning-fast response capabilities, unmatched multimodal intelligence, and remarkable accuracy across various tasks, further solidifying OpenAI’s dominance in the generative AI space. Unlike its predecessor GPT-4, which already made significant strides in language understanding and content creation, GPT-4o pushes the boundaries by integrating multimodal functionality—allowing it to seamlessly interpret and respond to not only text but also images and, in future versions, even audio. This positions GPT-4o as a versatile powerhouse for users who rely on AI for diverse applications ranging from creative writing and software development to STEM problem-solving and natural human-like conversation.

All ChatGPT Plus subscribers will be automatically upgraded to GPT-4o without any manual intervention, ensuring a smooth transition to the new standard in AI interaction. Meanwhile, GPT-4 will still remain accessible to developers via the OpenAI API, preserving its utility for those with specific deployment needs. GPT-4o has been engineered for speed and precision, making interactions more fluid and efficient while enhancing the user experience across a variety of professional and personal tasks. Whether it’s coding and debugging, generating high-quality written content, solving complex mathematical problems, or maintaining nuanced and context-aware conversations, GPT-4o outperforms previous versions across the board.

OpenAI’s investment in the GPT-4 family has been substantial, with over $100 million reportedly spent on training the models. This strategic expenditure reflects the company’s long-term vision of leading AI innovation, despite facing scrutiny regarding its data practices. OpenAI has firmly stated that its models are trained using only publicly available data, countering criticisms from outlets like The New York Times about the alleged unauthorized use of content.

In an unexpected twist ahead of the GPT-4o launch, OpenAI’s platform experienced a massive surge in user traffic due to the viral popularity of its new Ghibli-style art generator. This feature allowed users to create stunning, animation-inspired visuals, capturing the imagination of AI enthusiasts worldwide. The demand was so intense that CEO Sam Altman had to urge users to temporarily reduce usage to prevent system overload, underlining the immense popularity and potential of AI-driven creative tools.

The release of GPT-4o marks a significant milestone in the evolution of artificial intelligence. It not only redefines performance standards in AI models but also expands the horizons of what machines can do—blending speed, versatility, and intelligence into one unified system. As AI continues to reshape the digital landscape, GPT-4o represents the next big step in providing users around the globe with smarter, faster, and more capable tools.
