OpenAI is testing a watermark feature for its Image Generation model within the ChatGPT 4o framework, primarily due to the popularity of users generating Studio Ghibli-style art. The watermark will be applied to images created by free users, while ChatGPT Plus subscribers will have the option to save images without the watermark. There are ongoing developments for an ImageGen API, allowing developers to create their own applications.

OpenAI is experimenting with visible and invisible watermarks for images generated by its ChatGPT-4o model to enhance content traceability and compliance. The visible watermark, labeled “ImageGen,” is being tested for free-tier users while paid users will receive images without watermarks. This move aligns with broader industry efforts to improve attribution for AI-generated content.
