Openai sets out thoroughly in vibe coding and declares that “mature experiences” are on the horizon

OPENAI’s DevDay 2025 has focused on the mood coding. The company, which is now boasting of more than 800 million weekly active users for Chatgpt, announced a variety of new tools for developers during its annual event in San Francisco. At the top of the billing of ads: the possibility of creating applications directly in Chatgpt (including the possible authorization of “mature experiences” once the age check in place) and the introduction of a toolbox that will help users to create and deploy their own AI agents.

As part of OPENAI’s apparent efforts to transform Chatgpt into a complete front-end development environment, the company has announced its new Application SDK (Software Development Kit) which will allow developers to extract third-party applications supported to perform tasks. In a demo, the company showed Chatgpt working with Zillow to generate a menu of houses available for sale in Pittsburgh. Zillow created an interactive card based on the prompt and the user was able to ask additional questions depending on the card. The functionality should allow users to create tools using third -party applications, which they can preview directly in Chatgpt.

According to Openai, the SDK apps is available immediately for free, Go, Plus and Pro packages. Assistance will be available from the start for Booking.com, Canva, Racera, Figma, Expedia, Spotify and Zillow. The company also said that it was planning to offer support for Doordash, open, Target and Uber in the near future. For the moment, users will only be able to create and use the applications only seen, but it is planned to allow developers to submit applications later this year, with a planned application repertoire so that developers can share their atmosphere -based creations.

There are still a lot of details to come concerning what comes from the SDK apps. Altman has promised that monetization guidelines, for example, are in preparation. Also on the way: “mature experiences”. According to the directives of OPENAI application developers, “applications must be adapted to the general public, including users aged 13 to 17. Applications cannot explicitly target children under 13.” But this will not always be the case. “The management of experiences for adults (18 and over) will arrive once age verification and appropriate controls will be in place,” read.

The company recently introduced age verification tools designed to pass minor users to a chatgpt experience with much stricter directives following an unjustified death trial brought against the society by the family of a suicide deceased after long conversations with the chatbot. It seems that once these details settled, this will open the valves to more “adult” functions.

In addition to the SDK apps, the company has also deployed its API Agentkit (Application Programming Interface), which will allow users to create their own agentic AI tools. This is a significant extension of the OpenAi agent, previously introduced with the promise that the system could navigate the web independently to accomplish the tasks assigned to it by the user.

True to the theme of the mood coding, the main feature of Agentkit is its agent builder, which allows users to program the functionality of their AI agent via a visual interface. Altman described it as Canva for construction agents, making it more accessible to those who are less technical.
