Glide is much more structured. I gave it a real test on one of my repos and it outlined something I would expect from a junior engineer who messed up a lot of little details- e.g. function names and parameters were slightly off. I think if there was a type evaluation step/it was typescript-specific it would match an engineer with 3-9mo of experience (great!). But it failed to match basic codebase conventions e.g. using require on a codebase that is all imports.
For the authors, I would recommend using GPT4-turbo and huge context windows, or have an option to upload an OpenAI key. GPT3.5 is just not worth it- and I do sort of suspect GPT4 isn't being used because of the speed of the output but I'm not sure.
