Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for dynamically performing website creation. In some implementations, a server receives request data specifying a natural language description of a webpage modification. The server determines web development tasks corresponding to the webpage modification. The server determines web development tools configured to execute the web development tasks. The server generates prompt data for trained machine learning models. The prompt data includes instructions for generating a code update segment for the webpage modification. The server obtains from the trained ML models output data for the code update segment. The code update segment causes the web development tools to execute the tasks. The server generates a deployment artifact by executing the code update segment. The server provides an instruction that causes the computing device to display a representation of a modified webpage based on the deployment artifact.
