Distillation validation checkpoints
Final weights from the distillation validation ladder in
distillation/validation
of lm-exploration (campaigns distill-validation-20261023-01, -02-covering and
-03-qwen-200m). Results, grades and completions for every checkpoint are in the HF
dataset jfrick/lm-exploration-results, folder distillation-validation/.
<campaign>/students/<arm>/model.pt: from-scratch students (PyTorch state dict withconfigandsettings) for the modern decoder intraining/10m/model.py. Trimmed and covering arms use a 16,384-entry subset of the Qwen3.5 tokenizer (rebuilt from the shards injfrick/qwen35-distillation-shards-20261023); full arms use all 248,320 IDs.<campaign>/control/<run>/model/: Qwen3.5-0.8B-Base fine-tuned on the same stream (text-onlyQwen3_5ForCausalLM, FP32 safetensors, servable by vLLM 0.32).
The teacher's solutions were not verified for semantic correctness. Base model license: Qwen3.5-0.8B-Base (Apache-2.0).
