So it was, especially with our earlier models, I think the models are now smarter, but they kept producing, like, code snippets and thought, like, they can reference to previous you know, variables and functions, definitions. Which, if you had only normal code execution, like, you run the code snippet, and then you finish, It wouldn't work. So you need some kind of rebel environment.”
