# D24 v6

Public project index for the complete D24 v6 training lineage.

| Stage | Loadable model | Retained full-state checkpoints |
|---|---|---:|
| Pretrain | [`sfanm/d24-v6-pretrain`](https://huggingface.co/sfanm/d24-v6-pretrain) | 23 (`iter_0004000` through `iter_0084527`) |
| Midtrain | [`sfanm/d24-v6-midtrain`](https://huggingface.co/sfanm/d24-v6-midtrain) | 12 (`iter_0002000` through `iter_0023842`) |
| SFT | [`sfanm/d24-v6-sft`](https://huggingface.co/sfanm/d24-v6-sft) | 2 (`iter_0001600`, `iter_0001773`) |

Lineage: nominal ClimbMix-400B pretraining (354,530,270,862 consumed training
tokens) → 100,000,595,968 tokens of replay-free OLMo-3/Dolmino midtraining →
no-GSM8K simple-chat SFT (475,114,114 packed tokens).

Each stage repository exposes its terminal BF16 Transformers model at the root
and stores every retained resumable Megatron checkpoint under `megatron/`.
