# d12 baseline runner. Runs INSIDE a RunPod pod.
|
||||
# Pipeline: tokenizer -> base_train -> base_eval -> SFT -> chat_eval -> report.
|
||||
# On exit:
|
||||
# success -> upload final cache to HF, self-delete pod
|
||||
# failure -> upload logs + report dir to HF under _failures/, self-delete pod
|
||||
# (set UPLOAD_FAILURE_CACHE=1 to also dump partial cache for offline debug)
