Snowball 67B-A2B RLVR1 data These are the exact Parquet inputs retained for the Snowball 67B-A2B sync and async RLVR1 experiments on Iris cw-rno2a in September 2026. The data was selected from the skyrl_gym route of a TaskTrove conversion of the public NVIDIA Nemotron RL Ultra training blend, preserving source order and holding out the last 100 selected rows. See provenance.json for the local conversion and filtering record. The original TaskTrove release is also public.… See the full description on the dataset page: https://huggingface.co/datasets/open-athena/Snowball-67B-A2B-RLVR1-Repro-Data.
