OpenDCAI /DataFlex

DataFlex：面向大语言模型以数据为中心训练的统一基准与评估平台

OpenDCAI /DataFlex-Doc

DataFlex is a data-centric training framework that enhances model performance by either selecting the most influential samples, optimizing their weights, or adjusting their mixing ratios.

haolpku /DataFlex-RL

A Data-Centric RL and On-Policy Distillation Framework for LLM Post-Training

Yaxin9Luo /LLMSurgeon

(ACL 2026 Main) LLMSurgeon recovers the pretraining data mixture of any LLM from only its generated text — no weights, no training data. A calibrated domain classifier plus label-shift correction de-blurs biased predictions. Ships with LLMScan, a benchmark on 8 open-source LLMs.

mixing-floor /compute-floor

Repository containing paper's code, results, and LaTeX source.

liujin99 /climbmix

Unofficial reproduction of Nemotron-CLIMB (CLustering-based Iterative Data Mixture Bootstrapping, NeurIPS 2025, arXiv:2504.13161) on Ascend NPUs — 5 rounds, ≈3,900 NPU-hours; learned mixtures beat every fixed-ratio baseline (+0.014–0.043 STEM); the selection mechanism is the weak link — fixed and validated live.

roccoangelella /climbmix-token-mixture

Exact token-weighted cluster totals and reproducible calibration for NVIDIA Nemotron-ClimbMix
