Closest models by score

Similar positions on shared benchmark leaderboards. Smaller gaps are closer.

How similarity is measured

Mean absolute gap in percentile positions on shared benchmark settings; lower is closer. At least 60% overlap is required, with a minimum of three when available. Independent evaluations are used when there are at least three; otherwise published report comparisons are used. Repeated model observations within one setting are averaged before ranking. Writing-style traits and composite indices are excluded. This describes similarity, not an overall quality ranking.

POST-TRAINING / SOURCE DISCLOSURE

What the GLM-5.2 / GLM-5.3 report says

Z.ai says GLM-5.3 keeps the GLM-5.2 base and scales post-training on the same long-horizon stack: SAO, asynchronous slime training and a larger mix of environments and tasks.

  • Shared GLM-5.2 base checkpoint
  • Single-rollout asynchronous optimization (SAO)
  • Expanded long-horizon environment training

The launch report attributes the change to post-training, but its headline scores are publisher comparisons rather than a complete independent replication or an isolated optimizer ablation.

Every plotted observation links to its evaluation. Reported configurations, benchmark versions and task subsets can differ; similarity describes shared scores, not training lift.
