Readability (Perplexity)

Dropped

Models answer search questions. Graders rate whether answers are concise yet detailed and use markdown formatting well.

Perplexity reported it once, for Sonar, with no public method or data. The scoring method is not described, so model-judged is assumed.

Model scored in lab cards

Launch post lists it, from 1 lab

sonar leads with 85.9%

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

All the scores we have, one dot each, so a model tested at several settings appears more than once.
