A large language model, or LLM, is a model trained to work with language. In a drafting task it can generate text that fits the supplied context and instructions. The same model may help summarise a document, suggest wording, classify a request or prepare a first draft.
A fluent answer is not evidence
It is easy to read a well-written answer as if it had been checked against a reliable reference. That is a mistake. A model can produce a plausible statement, citation or explanation that is wrong. Its response also depends on the information and instructions available to it.
For quality and regulatory work, treat a generated response as material to assess. Check the actual source, whether it supports the statement, the date and scope of the source, and whether the conclusion fits the specific product, activity and market.
Give the task a usable context
State the purpose, intended reader and requested format. Supply the relevant controlled material through an approved route, identify the version and explain what the model should do when the information is incomplete. Asking it to flag an unresolved question is more useful than encouraging it to fill the gap.
A retrieval-assisted workflow can provide selected reference material with a task. This can make a draft easier to trace to the supplied information, but it does not automatically prove that the retrieved material is current, complete or applicable. Those checks remain part of the workflow.
Use the draft to support a decision
For example, ask for a comparison of two approved procedure revisions, with each proposed difference linked to the relevant passage. Review that comparison against the documents themselves before deciding what training or other action is needed.
The useful division of work is clear: the model helps organise and draft; the responsible people verify the evidence, resolve the open questions and decide what to accept. An attractive document is not an approved or correct document simply because it was generated quickly.
