The superficial alignment hypothesis is a theory suggesting that an LLM's fundamental knowledge and capabilities are almost entirely established during pre-training. According to this view, the fine-tuning phase does not add significant new knowledge but rather performs a 'superficial' adjustment, aligning the model's existing abilities with specific user needs and instruction formats. This explains why alignment can be achieved with a relatively small amount of fine-tuning data and effort.

Interpreting LLM Training Observations

A research team observes that a large language model, pre-trained on a massive text corpus, requires a surprisingly small dataset of instruction-following examples to become a helpful assistant. According to the Superficial Alignment Hypothesis, what is the most accurate explanation for this observation?

A colleague argues that the fine-tuning process is where a large language model learns most of its new skills and factual knowledge. Based on the idea that alignment is a 'superficial' adjustment, briefly explain why this argument is likely incorrect.
