- Composition: BabyLM 2026 official 10M natural corpus (unchanged; redistributed per challenge terms) blended per arm with: LLM-generated didactic text (competition pool 3.02M words final; d1conc 5.72M; d1spread 5.85M; d1social 9.57M), open-licensed textbook text (1.81M; Project Gutenberg PD children's literature/primers), and generator-rephrased natural text (1.76M, source = the removed 2M slice). Per-arm realized compositions: see paper Appendix A14 (all within 10M for competition arms).
- Generator: cyankiwi/Qwen3-30B-A3B-Instruct-2507-AWQ-4bit (revision 876f886e383033237a04d8634b5af1cde0818290), vLLM 0.9.2, llm.chat with model chat template, enforce_eager, temperature U(0.7,1.0) per prompt (rephrase/topup variants documented in released code), top_p 0.95, repetition_penalty 1.05.
- Budget accounting: whitespace word count; every arm's sum of all text seen <= 10M words (competition arms); diagnostics labeled over-budget in paper.
- RNG seeds: removal order + all sampling seed 42; round-2 pool shuffles seed 42; topup prompts seed 777.
- Source markers: NATURAL= DIDACTIC= TEXTBOOK= REPHRASED= (pre-existing tokenizer specials, index <16, never masked).
- Cleaning/decontamination: pipeline in released code (clean_dedup.py, decontaminate.py); 8-gram literal pass: 0 hits synthetic pools, 2 textbook; TF-IDF semantic pass drops 14-675/pool; EWoK canary UUID absent from all released files.
- Tokenizers: one per arm, vocab 16384, trained on that arm's exact mix; pairwise vocab Jaccard 0.81-0.88.
- Known register properties: Flesch-Kincaid ~2.6 (synthetic), 5.5 (rephrased), ~12 (textbook).
