Finally, we have introduced a method for further fine-tuning the model on additional reaction data. By using this further mixed fine-tuning we have substantially improved the model's top-1 reactant-accuracy on ring formation reactions published in 2022 from 0% to 89.9% without significantly compromising performance for older ring formation reactions or other reaction classes. While this approach has been applied to a small dataset of less than 1.5k heterocycle formations, it has the potential to be scaled up for a larger dataset or a different reaction class.
