Long-context benchmark for recovering parent relationships inside graph tasks.
BenchLM is tracking Graphwalks Parents 128K in the local dataset, but exact-source verification records for these rows are still being attached. To avoid a blank benchmark page, BenchLM shows the current tracked rows below as a display-only reference table.
These tracked rows are useful for inspection and spot-checking, but until exact-source attachments are completed they should not be treated as fully verified public benchmark rows.
BenchLM mirrors the published tracked score view for Graphwalks Parents 128K. GPT-5.4 leads the public snapshot at 89.8% , followed by GPT-5.4 mini (71.5%) and GPT-5 mini (64.3%). BenchLM does not use these results to rank models overall.

The published Graphwalks Parents 128K snapshot is tightly clustered at the top: GPT-5.4 sits at 89.8%, while the third row is only 25.5 points behind. The broader top-10 spread is 39.0 points, so the benchmark still separates strong models even when the leaders cluster.
4 models have been evaluated on Graphwalks Parents 128K. The benchmark falls in the Reasoning category. This category carries a 17% weight in BenchLM.ai's overall scoring system. Graphwalks Parents 128K is currently displayed for reference but excluded from the scoring formula, so it does not directly affect overall rankings.
