I have been testing the various models, and I would not call Fable SOTA.
I can't actually get Fable to do anything. I only work on back-end code, and the moment Fable notices the jwt scope checks on the endpoints it's game over, it refuses to do anything because security is involved.
So for me, Fable is completely useless, the bar is very low, any llm that will actually attempt the task beats it every time.
It has been fine for me for weeks of work in a mobile app, but yesterday I ran into the same limitation.
For implementing a feature where browser credentials need to be handled securely in the app, Fable refuses to work.
