DragonCode Tokenized Pretrain — Domain-Code Corpus

Pre-tokenized training corpus for the DragonCode LLM family. This is the domain-code-only dataset (not general web text).

Format

26 shards: data/train-00000-of-00026.bin .. train-00025-of-00026.bin
Flat int32 little-endian token-id stream (no headers, no row structure). Concatenate shards in order to reconstruct the full sequence.
3,417,141,141 tokens total (~3.42B), ~13.67 GB on disk.
Sequence length: 4096 (MAX_SEQ_LEN) during training.

Sources (streaming, permissive only)

Source	Field	License filter
`codeparrot/codeparrot-clean`	`content`	permissive only (MIT/ISC/Apache-2.0/BSD/CC0/Unlicense/etc.)
`open-r1/codeforces-cots`	`prompt` / `generation`	permissive only

Non-permissive-licensed and empty samples are dropped. General web corpora (FineWeb-Edu / SlimPajama / The-Pile) are intentionally excluded per project spec.

Tokenizer

Uses the DragonCode tokenizer (see DragonLimited/DragonCode-150M). Encode with add_special_tokens=False.

Note

The previous 5-shard legacy corpus (FineWeb-Edu-based) was fully replaced by this domain-code corpus on 2026-08-25.
