A recent update to the ChatGPT web interface quietly added a new “GPT‑4o Image Generation” option inside the Custom GPT builder, signalling that OpenAI is preparing to let user‑created bots generate pictures with the same natively multimodal model that powers ChatGPT’s own image tool. The setting, first noticed in the April 18 refresh, replaces the long‑standing DALL‑E 3 backend, suggesting full feature parity when the rollout begins.

If enabled, Custom GPTs will be able to translate prompts directly into photorealistic or stylized visuals without routing through an external image service. That shift should streamline creative workflows, letting domain‑specific assistants—whether a fashion stylist or a biology tutor—produce, edit, and refine images in the same conversational thread, thereby offering a more dynamic, engaging experience for end users.
GPT‑4o’s image model, introduced to the main ChatGPT product on March 25, delivers sharper text rendering, stronger attribute binding, and consistent character depiction by generating images autoregressively rather than with diffusion, an innovative approach that improves accuracy even if it takes a few extra seconds to render.
You can try our "Cyberpunk Artist" GPT, where 4o image generation is enabled. Keep in mind that it is still experimental, and it often doesn't follow GPT instructions. In our tests, it worked properly only in 50% of cases.
Extending those enhanced capabilities to Custom GPTs could prove significant for developers and enterprises. The forthcoming support also hints at a single multimodal stack across ChatGPT, Sora, and the API, ensuring broad availability and reducing fragmentation.
OpenAI has not announced timing, but the in‑product toggle typically precedes a graduated rollout to Plus, Pro, and Team tiers. Once live, creators should easily switch existing bots to GPT‑4o images, improving user engagement with an exciting enhancement that promises a better overall experience.
