An engineering team is refining a large language model. During one step of the process, the model is given the start of a sentence, 'The best way to learn a new skill is'. The model then calculates a probability for every word in its vocabulary to be the next word and uses this distribution to generate a complete sentence. The model's internal parameters are then updated based on a separate quality assessment of the generated sentence. Which part of this process best describes the primary role of the model being actively trained (the 'policy model')?
