# Slayer1B 1.04 — training checkpoints

Full trainer checkpoints of continued pre-training of [Slayer1B 1.03](https://huggingface.co/SlayerLab/Slayer1B-1.03)
from its final checkpoint ([`ckpt_7150.pt`](https://huggingface.co/SlayerLab/Slayer1B-1.03-checkpoints), sha256
`d7cad967…`). Each file holds the model weights **and the optimizer state**.

**Status (28 October 2026): complete.** Release [Slayer1B 1.04](https://huggingface.co/SlayerLab/Slayer1B-1.04) is the
state at step 10010 (`ckpt_10010.pt`). This repository holds every checkpoint of the 1.04 run (7200–10010, 58 files)
and, because the run continued without a break, also the checkpoints of the next two releases (10050–13848, 78 files):

| release | steps | files | per-release repository |
|---|---|---:|---|
| 1.04 | 7151–10010 | 58 | this repository |
| [1.05](https://huggingface.co/SlayerLab/Slayer1B-1.05) | 10011–12870 | 58 | [Slayer1B-1.05-checkpoints](https://huggingface.co/SlayerLab/Slayer1B-1.05-checkpoints) (same files) |
| [1.06](https://huggingface.co/SlayerLab/Slayer1B-1.06) | 12871–13848 | 20 | [Slayer1B-1.06-checkpoints](https://huggingface.co/SlayerLab/Slayer1B-1.06-checkpoints) (same files) |

| | |
|---|---|
| Start | 1.03 `ckpt_7150.pt` (step 7150, constant lr 6e-4) |
| Steps | 7151 → 10010, 1 048 576 tokens per step (256 sequences × 4096 tokens) |
| Schedule | **constant lr 6e-4**, no decay |
| Data | [SlayerLab/slayer-pl-8x3b](https://huggingface.co/datasets/SlayerLab/slayer-pl-8x3b) revision `d50df04a`, continuing the single pass over the corpus: tail of pack-03 (steps 7151–7192), pack-04 from step 7193, pack-05 from step 8991 |
| Leak-scan exclusion | from pack-04 on (step 7193), the 5133 documents with n-gram overlap with BoolQ / MMLU / ARC test items are excluded (list sha256 `84caed78…`); steps up to 7192 used the unfiltered data |
| Hardware | 4 × NVIDIA L40S (48 GB), DDP. Training paused (budget) at step 8300 and resumed from `ckpt_8300.pt` |
| Checkpoints | every 50 steps from 7200, and 10010; all are constant-lr states |
| Trainer | `train_gpt_ref` r24.1 (sha256 `881cb055…`); model definition `train_gpt_ref_r23.py` (unchanged). Steps 10011–13848: `train_gpt_ref` r24.2 (sha256 `46f83b51…`) on 8 × L40S |
| Training curve and evaluations | https://track.fabryka.ai/run/f056bb5c-f1da-56d5-9776-cc33063f10a5 |

## SHA-256 (steps 7200–10010)

Each value equals the LFS object id of the file in this repository (checked anonymously after upload).

## File format

`torch.save` dictionary of the trainer: `model`, `opt` (Muon + AdamW), `step`, `config`. Load with
`torch.load(path, map_location="cpu", weights_only=True)`. Model class: `train_gpt_ref_r23.py` in the model
repositories (1.00–1.06). Every file is 8 860 287 151 bytes.
