How can i play with a model

One thing i want is to play the model myself. How can i replace one of the playing models output with my own. With just text input for simplicity?

The issue names no files, tests, or entry points. Start by locating the code that runs a model turn and handles player input, then clarify whether the expected result is documentation or a new interaction path. Done should let a person substitute one model's output with text input and clearly explain how to use it.
