Present does not mean used well

Suppose "booking required" is still in the request, but the draft invitation leaves it out.

The model did not necessarily run out of room. Information can fit in the context and still be overlooked or used incorrectly.

In a 2023 study, models answering questions over long inputs often performed worse when the relevant information was in the middle. The result varied with the model and task. A larger window was not a guarantee of reliable use.

Give the model a concise current brief, separate requirements from background, and check the result against those requirements.

Putting a paper on a desk makes it available. It does not guarantee that every detail reaches the finished invitation.
