OpenAI has made its image generator, powered by the GPT-4o model, accessible to all users, CEO Sam Altman announced on X. Previously, this feature was available only to paying ChatGPT subscribers.

While there is no clear indication of how many images free-tier users can create, Altman previously mentioned a possible limit of three per day.

The tool has seen massive demand since its launch, with Altman joking that OpenAI's GPUs were 'melting' under the pressure. However, it has also sparked controversy, particularly after users began generating images in the style of Studio Ghibli, raising copyright concerns.

Others have used the generator to create fake receipts, such as restaurant bills. OpenAI has responded by stating that all AI-generated images contain metadata identifying them and that the company takes action when violations occur.

In a major financial development, OpenAI has secured$40 billion in funding from SoftBank, valuing the company at$300 billion. The company also revealed that ChatGPT now boasts 500 million weekly active users and 700 million monthly active users, marking a significant milestone in its growth.
