Approach Before discussing the different applications in detail, let us first discuss how we fine-tune the GPT-3 model in practice for a simple but highly non-trivial example. High entropy alloys have attracted much interest as a novel class of structural metals. Interestingly, one has a sheer infinite number of possible combinations of metals. From a practical point of view, it is important to know if a given combination of metals will form a solid solution or multiple phases. Hence, the question we would like to ask is "What is the phase of <composition of the high entropy alloy>?" and our model should give a text completion from the set of possible answers {single phase, multi-phase}.
