How this is ranked: ELO scores from blind human preference (people compare two outputs and pick the one they prefer) — rankings by Artificial Analysis. Open-weight means the model can be downloaded and run on your own hardware; where we cannot confirm it, we mark the model unverified rather than guess. See the full media model leaderboard.
