| # 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. |
|

| | 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. |

| `add_special_tokens=False`. |
|
|
| ## Note |

| domain-code corpus on 2026-08-25. |
