OpenAI Updates ChatGPT Sites with Collaboration Tools, Custom Domains, and Faster Deployment

OpenAI has updated ChatGPT Sites with a "Build Together" collaboration feature, allowing team members to co-develop, edit, and publish web applications directly. Additionally, the update cuts site deployment times by roughly half, enables custom domain binding, and introduces natural language database inspection. This update transforms ChatGPT Sites from a single-user prototyping tool into a practical collaborative web development environment for teams. Faster deployment speeds and custom domain support significantly lower the barrier for quickly building and launching custom web tools using natural language. Invited team members can now edit, save, and publish site changes, as well as inspect attached database contents using natural language prompts without opening separate database managers. Projects can also be kept private for internal testing before launch, and users can bind their own custom domains instead of relying on generic URLs.
