Scoring the FLUF(F) Test Rubric: Identifying Inaccuracies in GenAI Output
FLUF comes in many shapes and forms and can be applied to a variety of AI results including images or text/LLMs.
In this example, we see two infractions - an issue with the Format length, and with the Usability credibility. The FLUF score is two (2).
Note that for each error there is a plus or a point assessed as an infraction.
Any score other than zero means re-prompting, regenerating, and repeating until you get the intended result.
