JupiMind datasets

This repository stores normalized dataset snapshots used for JupiMind training workflows. The primary asset at the moment is the pretraining mix built for aevynt/JupiMind-Dense-J1R-Tokenizer-24k.

Files currently included

• pretrain/j1r_24k_7b_mix/j1r_t4x4_24k_mix.jsonl
• pretrain/j1r_24k_7b_mix/j1r_t4x4_24k_mix.summary.json

Main dataset: J1R 24k 7B mix

• Type: pretraining JSONL
• Format: one record per line as {"text": "..."}
• Target tokenizer: aevynt/JupiMind-Dense-J1R-Tokenizer-24k
• Generated sequences: 1,710,000
• Target context length: 4096
• Estimated token budget: about ~7B tokens using chunk size 4094
• Original build output path: /home/trainer/jupimind/outputs/pretrain/j1r_t4x4_24k_mix.jsonl

Actual source mix after backfill

Two smaller technical sources did not contain enough material to reach their planned quotas, so the build pipeline backfilled the missing volume with fineweb2_vi. The table below reports the actual final composition, not the initial intended weights.

This repository does not apply a single blanket content license to the mixed dataset. Each source portion remains governed by its upstream terms. See LICENSE and SOURCES.md for details.

Usage notes

• This is a derived training mix assembled for pretraining, not a replacement distribution for the original source datasets.
• Downstream users are responsible for reviewing legal, safety, privacy, attribution, and redistribution obligations of each upstream source before training or deploying a model.
• VTSNLP/vietnamese_curated_dataset and common-pile/stackv2_edu_filtered require extra care because their final content rights depend on upstream components or per-document metadata.
