If model-based testing has been selected for the overall test automation approach for a project,...

In model-based testing, the test cases are derived from a model that represents the desired behavior of the System Under Test (SUT). This model serves as the basis for generating test cases, which means the test generation layer will be automated based on the defined model. However, all other layers of the Test Automation Architecture (TAA), such as the execution layer, test script layer, and the adaptation layer, are still utilized. The model informs the generation of test cases but does not eliminate the need for the other layers, as they play crucial roles in the execution and management of the tests. References = The ISTQB Test Automation Engineer syllabus discusses the influence of model-based testing on the layers of the TAA, emphasizing the automation of the test generation layer while retaining the other layers123.
