Parallel Language Models - HumanEval: leaderboard

Parallel Language Models (2026): post-trained 1.3B and 3B research checkpoints with explicit beta and decoding configurations. The 3B autoregressive result uses the same PLM checkpoint in AR inference mode, not a separately trained AR model. GSM8K was used to select learning rates and epochs (Appendix A7.SS3), so its reported score is a development metric; other task scores are kept distinct. Throughput is excluded. Score (%); higher is better.

Metric: Score (%). Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 6 models tracked.
