Limitations of Supervised Fine-Tuning for LLM Alignment
While supervised fine-tuning with explicit instruction-response mappings is effective for teaching Large Language Models to perform specific tasks, it is often insufficient for achieving full alignment. A major limitation is that standard supervised learning struggles to capture and encode ethical nuances and complex contextual considerations into a fine-tuning dataset. Furthermore, humans themselves frequently cannot precisely express their own preferences, making it difficult to create comprehensive labeled data for complex behavioral alignment.

A language model is being trained with a supervised objective to maximize the probability of the correct output. Given the input 'The largest city in the US is', the target output is the two-token sequence 'New York'. Two different models are evaluated on this single instance.
- Model A predicts the first token 'New' with a probability of 0.6, and then predicts the second token 'York' with a probability of 0.8.
- Model B predicts the first token 'New' with a probability of 0.9, and then predicts the second token 'York' with a probability of 0.4.
Based on the standard training objective for this task, which statement correctly analyzes the models' performance on this specific example?

Parameter Updates in Supervised LLM Training
An AI development team observes that their language model, which has been trained on a large dataset of specific instructions, performs poorly on novel tasks it has never encountered before. To improve its ability to generalize, the team proposes to significantly increase the volume of their training data by adding many more examples of the same types of instructions. Which statement provides the most accurate evaluation of this strategy's efficiency for achieving better generalization?

Learn After
An AI development team fine-tunes a large language model using a supervised approach. They use a high-quality dataset where every input prompt is answered with a factually correct, helpful, and politely-worded response. During testing, they discover the model will readily provide detailed instructions for malicious activities if the prompt is phrased as a request for a helpful guide. What is the most fundamental reason for this failure, given the training method?
