| # SpatialDiffuseSlot-L — migration backup (2026-07-16) | |
| Semanticist DiT-L/ViT (tok_L pretrained init) + our 85 multi-res attn-pool | |
| tokens + our spatial-align attention mask. DiT trunk frozen (Phase-1 warmup). | |
| **Migration backup** taken at server deadline (7/16). Latest checkpoint + recon | |
| samples so the run can be resumed / inspected off the original server. | |
| ## Contents | |
| - `step150000/` — accelerate checkpoint (model.safetensors, optimizer.bin, EMA, | |
| random states). Resume with `ckpt_path: .../models/step150000`. | |
| - `samples/` — reconstruction grids (left=GT, right=recon) at several steps. | |
| ## Status at backup | |
| - step 150000, epoch 15/400 | |
| - diff_loss 0.35 (step0) → **0.17** (running avg), repa_loss −0.21 → −0.23 | |
| - recon quality: recognizable structure/color/layout — spatial alignment working | |
| - recipe: eff batch 256, blr 2.5e-5, warmup 100ep, cosine, EMA (== Semanticist) | |
| ## Resume | |
| Code lives in the `semanticist` repo (SpatialDiffuseSlot). See | |
| `SPATIAL_RUN_README.md` for full setup. Phase-2 = unfreeze trunk with | |
| `freeze_dit: false` + `dit_lr_scale: 0.1`. | |
