OpenAI is currently testing a watermark feature for its Image Generation model within the ChatGPT 4o framework. This development comes as users increasingly create Studio Ghibli-style artwork using the ImageGen model, reported BleepingComputer. The Image Generation model has become a focal point for discussions about ChatGPT, and is recognised as an advanced multi-model release. It allows users to produce images with text and generate visuals similar to those by the Japanese studio, Studio Ghibli.
Previously, the ImageGen model was exclusive to ChatGPT Plus subscribers, but it is now available to all users, including those with free accounts. AI researcher Tibor Blaho has noted OpenAI’s efforts to introduce a watermark for images generated by free accounts. Blaho wrote on X (formerly Twitter) that the watermark, referred to as “image-gen-watermark-for-free,” is present in the beta version of the ChatGPT Android app.

ChatGPT Plus subscribers can save images without a watermark, although OpenAI has not confirmed whether this feature will be a permanent fixture. The company’s plans remain adaptable. OpenAI is also considering the introduction of new tools, potentially including “Structured Thoughts,” “Reasoning Recap,” “CoT Search Tool,” and “l1239dk1.”
“GPT‑4o image generation excels at accurately rendering text, precisely following prompts, and leveraging 4o’s inherent knowledge base and chat context—including transforming uploaded images or using them as visual inspiration,” said OpenAI in a recent blog post. “These capabilities make it easier to create exactly the image you envision, helping you communicate more effectively through visuals and advancing image generation into a practical tool with precision and power.”
“We trained our models on the joint distribution of online images and text, learning not just how images relate to language, but how they relate to each other. Combined with aggressive post-training, the resulting model has surprising visual fluency, capable of generating images that are useful, consistent, and context-aware,” noted OpenAI.
In addition, OpenAI is working on an ImageGen API to allow developers to create their own products.
OpenAI and Google opposed UK AI copyright proposals
Last week, OpenAI and Google opposed the UK government’s proposed measures on AI and copyright. Their responses to a consultation that concluded in February add pressure on the government, which has faced criticism from creatives and lawmakers.
The UK Parliament’s Science, Innovation and Technology Committee requested these submissions following the decision by representatives from both companies not to provide evidence to MPs regarding their positions. The consultation proposed changes to copyright law, allowing AI firms to use public content for model training without permission from rights holders unless they opt out. This proposal also includes increased transparency requirements for AI companies.
