# LAION Box — Work in Progress 0.7

Work-in-progress LoRA fine-tune (rank 256) of the DramaBox / LTX audio DiT on a
diverse mix: German (70%, 3-mode standalone/voice-clone/concat) + diverse-mix (30%).

**This repo is updated automatically by a training daemon.**

Layout:
- `latest/` — most recent validated checkpoint (overwritten each save).
  - `lora.safetensors`, `training_state.pt` (optimizer/scheduler for resume), `metadata.json`
- `best/step<N>/` — the two best checkpoints so far by mean flow_loss (last-20 window).
  Pruned to two; stale ones are removed when the best set changes.

Checkpoints are validated before upload (safetensors header + finiteness spot-check,
optimizer-state size check, flow-loss sanity).
