There are two technical approaches to vertical-domain knowledge injection: one is injecting domain knowledge at the foundation model level through fine-tuning, which requires large amounts of annotated data and offers low flexibility; the other is keeping the foundation model unchanged and dynamically injecting knowledge at inference time through tool calls, RAG, or structured prompts, which offers higher flexibility but places greater demands on prompt engineering.
