| Diagrams, arrows, fixed layouts | gdm:nbp or gdm:nb2 |
| Photographic or painterly | gdm:nbp |
| Cheap, fast exploration | gdm:nb2, or gdm:nb2-lite at about 3 s |
| Top benchmark score, time no object | oai:gi2.5 |

Arena: text-to-image leaderboard, votes to
24 September. Arena scored oai:gi2 at medium and gdm:nbp at 1K, and names no setting for
the rest. n/a means it lists only a variant genimg does not use. Artificial Analysis scores
within about ±9 points tie.
