# devops-300m-base — Recovered Base Checkpoint

Recovered 2026-09-20 from /home/dkaiser/sft-training/devops-300m-prepped/
after the original outputs/devops-300m-4096-bf16-vast/ was lost in a
working-copy rsync incident on big-ai.

Provenance chain:
1. Trained on vast.ai (2x RTX 4090, bf16, 4000 steps, seq 4096)
2. Fetched to big-ai outputs/devops-300m-4096-bf16-vast/
3. prep_for_sft.py converted to HF LlamaForCausalLM format (vocab 65539,
   +3 chat special tokens) -> sft-training/devops-300m-prepped/
4. This copy = the prepped base weights (identical to trained checkpoint,
   HF-native format, loads via AutoModelForCausalLM)

macpro mirror (/mnt/1tb_store/vastai/) was empty at recovery time.
