Slayer1B 1.06 — training checkpoints
Full trainer checkpoints of the run that produced Slayer1B 1.06:
pre-training continued from ckpt_12870.pt (sha256 435082ff…). Each file holds the model weights and the
optimizer state. Release 1.06 is the state at step 13848 (ckpt_13848.pt).
Status (28 October 2026): complete — 20 files. All copies have completed anonymous read-back verification. The LFS object ids and sizes of all 20 files were independently compared with the verified source list on 28 October 2026: no missing files or mismatches. The same files are also in Slayer1B-1.04-checkpoints, which collects the whole continuation 7200–13848.
| Start | ckpt_12870.pt (step 12870, constant lr 6e-4) |
| Steps | 12871 → 13848 (978 steps × 1 048 576 tokens = 1 025 507 328 tokens), 256 sequences × 4096 tokens per step |
| Schedule | constant lr 6e-4, no decay |
| Data | SlayerLab/slayer-pl-8x3b revision d50df04a, continuing the single pass over the corpus. The segment ends where the corpus pass ends (14 520 680 448 tokens in total, one epoch). |
| 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…); this whole segment is filtered (steps up to 7192 were not) |
| Hardware | 8 × NVIDIA L40S (48 GB), DDP; global batch identical to the 4 × L40S run of 1.04 |
| Checkpoints | every 50 steps, and the final step 13848; all are constant-lr states |
| Trainer | train_gpt_ref r24.2 (sha256 46f83b51…); model definition train_gpt_ref_r23.py (unchanged) |
| Training curve and evaluations | https://track.fabryka.ai/run/f056bb5c-f1da-56d5-9776-cc33063f10a5 |
