Self-healing Generate Object Function Call like Instructor

[feliche93]

I would love to see if there would be some functionality for the generateObject function like there is with instructor.

The idea is in short, that if validation fails the output is put again into a function call with the zod validatin errors, so the model gets a second (or X number of chances) to "fix" any wrong output.

Probably using the maxRetries param for this could be confusing for other users, so not sure what the most elegant API design for this would be. 🤔
