OpenAI’s latest upgrade to ChatGPT introduces a powerful AI image generation tool, powered by its advanced GPT-4o model. This new feature enables users to create ultra-realistic and highly detailed images from text prompts directly within ChatGPT.
But there’s a catch—free-tier users will have to wait longer to access it.
Unexpected Surge in Demand
According to OpenAI CEO Sam Altman, demand for the feature has far exceeded expectations.
“Images in ChatGPT are way more popular than we expected (and we had pretty high expectations),” Altman tweeted.
The overwhelming response has strained OpenAI’s GPU resources, prompting the company to prioritize premium subscribers for stable access.
Currently, only ChatGPT Plus, Pro, and Team users can generate images. Free-tier users—who were originally expected to gain access shortly after the initial rollout—are now restricted to just three images per day once the feature becomes available to them.
What Makes GPT-4o’s Image Generator Special?
The GPT-4o model introduces a new level of sophistication in text-to-image generation using an autoregressive method. It builds images pixel by pixel, from left to right, top to bottom, leading to:
- Sharper, more coherent results
- Faster rendering speeds
- Better texture and color realism
Users who have tried it report stunning lifelike portraits, detailed illustrations, and even artistic interpretations that rival human creativity.
Why the Delay?
The primary reason is GPU bottlenecks. AI-generated images require massive processing power, and with global interest skyrocketing, OpenAI’s infrastructure is stretched to the limit.
“Our GPUs are under serious strain,” the company said in a blog post. “To ensure service stability, we’re temporarily limiting access.”
Until the system is optimized and capacity expanded, free-tier users will remain on hold for full access.
What’s Next for Free Users?
There’s no confirmed timeline for when unlimited image generation will reach non-paying users. However, OpenAI has assured the public that it’s working on efficiency improvements and infrastructure scaling to meet the demand.
In the meantime, users eager to explore the tool can upgrade to ChatGPT Plus or Pro plans to enjoy unrestricted access and faster rendering.

Conclusion
While the delay is frustrating for free users, it underscores the massive popularity and potential of AI-generated visuals. As OpenAI works to scale its services, broader access is expected soon.
The future of AI creativity is here—just not fully open to everyone… yet.
