Delulu: leaderboard

Delulu evaluates code-generation models on fill-in-the-middle completion tasks across multiple languages, so the input modality is text/code. The pinned metric is pass@1, measuring whether the model’s first completion matches the verified target under the benchmark’s hallucination-focused evaluation. This is a source-attributed result table mirrored by BenchmarkList. Source: BenchmarkList’s attributed result table.

Metric: pass@1. Source: benchmarklist.com. Saturation forecast: Estimated already saturated. 11 models tracked.
