deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B @ ad9f0ae0864d7fbcd1cd905e3c6c5b069cc8b562 supervised-fine-tuned for one pass over the 6400 pre-registered sft_train rows of cmpatino/direct-opd-sft-deepmath-pilot-data @ 22625ae5db434947195bf862c429cd94504a4809.

This is an experiment artifact of the Direct-OPD SFT-vs-RL policy-shift pilot: it is the SFT-shifted teacher whose divergence from the base teacher Phase 3/4 measures. It is not intended or evaluated as a general-purpose model.

Configuration (pre-registered)


steps / global batch	100 x 64 = 6400 examples (6400 rows available)
optimizer	AdamW lr 5e-06, betas (0.9, 0.95), eps 1e-08, wd 0.1 (no decay on 1-D params)
schedule	linear decay, 10 warmup steps, grad-norm clip 1.0
precision	fp32 master weights, autocast bf16 compute, bf16 checkpoints
max sequence	3072 tokens (prompt <= 1024, target + EOS <= 2048)
supervised tokens	10,950,054
seed	42 (data order `numpy.random.default_rng(42).permutation(n_train) [PCG64; NOT RandomState/MT19937], n_train=6400`)
attention	flash_attention_2 (requested `auto`)
target construction	completion-style: prompt via `add_generation_prompt=True`, target = `adapted_target` + EOS, prompt tokens masked with -100

checkpoint-20/ — optimizer step 20
checkpoint-40/ — optimizer step 40
checkpoint-60/ — optimizer step 60
checkpoint-80/ — optimizer step 80
checkpoint-100/ — optimizer step 100
repo root — same weights as checkpoint-100 (so from_pretrained works directly)
logs/run_manifest.json, logs/metrics.jsonl — full config, per-step metrics, tokenization statistics and every post-training assertion result

Tokenizer files are byte-identical to the base revision (asserted per checkpoint); the vocabulary and embedding matrices are never resized.
