SAN FRANCISCO — OpenAI has announced that its conversational AI model, ChatGPT, is now available to all users without the need for a waitlist. Users can sign up and start using the service immediately. This expansion follows months of testing and improvements to the system’s safety features.

ChatGPT, known for generating human-like text based on user prompts, has already attracted over 1.5 million active users who create more than 2 million images daily. The model has been utilized by a diverse group of professionals, including artists, authors, and architects. The feedback from these users has been instrumental in enhancing ChatGPT’s capabilities and safety measures.

One of the key features added based on user feedback is Outpainting, which allows users to extend images beyond their original borders. This feature, along with others like collections, has expanded the ways users can harness ChatGPT for creative projects.

OpenAI has also refined its safety protocols, making the model more robust against generating inappropriate content. This includes better filters to block sexual, violent, and other prohibited content, and improved detection techniques to prevent misuse.

In addition to the broad availability of ChatGPT, OpenAI is testing an API with select customers. This will soon be made available more broadly, enabling developers and businesses to integrate ChatGPT’s capabilities into their own applications.

OpenAI invites users to sign up and start exploring the creative possibilities with ChatGPT today.
