how does ai search grader works

[jasmin]

technically speaking, how do these grading tools score llm outputs?

yeah i've been wondering this too. from what i've seen, a lot of them use another llm to evaluate, like one llm grades another. or they have a 'reference answer' it tries to match up with. also heard about some just checking for certain keywords or structure. dunno if it's super fair sometimes tho tbh.

oh thanks that makes a lot of sense

AI search graders score LLM outputs by comparing them to reference answers or using "judge" LLMs to evaluate relevance. They analyze keyword density, structural alignment, and programmatic labeling to determine how well content satisfies specific search intents, ensuring visibility across modern, AI-driven search results.
