Does Oracle AI in Fusion Applications need calibration before using?

Large language models (LLMs) for generative AI don't need to be trained further. For predictive AI, the base models are trained on your data to tailor them further for your use. These calibrated models are embedded into Oracle Fusion Cloud Applications, and they can be used without further training. Other than enabling the features with AI, usually you don't need to do additional implementation. At least, it would be very minimal.
