-- Decision: Used plan mode because `workflows/benchmarking_workflow.md` explicitly requires planning before benchmark execution.
-- Decision: User selected full scope: `all 8 variants` and both `GGUF` and dense `safetensors` fp8/int8 paths.
-- Decision: Chose a focused-comprehensive benchmark matrix of `44 configs` instead of an exhaustive `549-630-config` Cartesian product because the latter would require excessive downloads/GPU time and produce an unreadable table.
-- Decision: Excluded `FLUX.2-klein-9B` from actual sweep after `snapshot_download` returned `GatedRepoError: 403 Client Error`; needs manual HF license acceptance.
-- Decision: Treated failures as benchmark findings, not harness bugs: dense int8 small-M failures, `mxfp8` unsupported, Flux T5 fp8 text-encoder failure, and FBCache GGUF slowdown.
-- Created task `#66`: `Benchmark all supported diffusion models across all optimization levers`.
-- Edited `/mnt/disks/unslothai/ubuntu/workspace_81/unsloth/scripts/diffusion_bench.py`: added/plumbed benchmark flags including `--transformer-cache {off,fbcache}` and related metrics/config output.
-- Created `/mnt/disks/unslothai/ubuntu/workspace_81/unsloth/scripts/benchall_orchestrator.py`: encodes the model/config matrix, runs `diffusion_bench.py` across GPUs, supports `--list`, `--gpu`, `--variants`, and `--aggregate`.
-- Created `/mnt/disks/unslothai/ubuntu/workspace_81/unsloth/scripts/benchall_predownload.py` via shell heredoc during predownload setup.
-- Overwrote `/mnt/disks/unslothai/ubuntu/workspace_81/unsloth/plans/wobbly-jumping-narwhal.md` with approved benchmark plan.
-- Created `/mnt/disks/unslothai/ubuntu/workspace_81/unsloth/outputs/diffusion_benchall/SUMMARY.md` with benchmark findings and headline tables.
-- Generated `/mnt/disks/unslothai/ubuntu/workspace_81/unsloth/outputs/diffusion_benchall/results.csv` from aggregation; contains `40 rows`.
-- Commands run: `ls workflows/benchmarking_workflow.md unsloth/workflows/benchmarking_workflow.md`, `ls parallel_planner.py gpu_pool_runner.sh`, `ls unsloth/scripts/diffusion_bench.py unsloth/scripts`; found workflow, planner, runner, `diffusion_bench.py`, `diffusion_quality.py`.
-- Command run: `python3 -u parallel_planner.py --output_file extra_plan.md --prompt ...`; background task completed and wrote `/mnt/disks/unslothai/ubuntu/workspace_81/async_task_outputs/extra_plan.md`.
-- Command run: `python -c "import ast; ast.parse(open('scripts/diffusion_bench.py').read()); print('bench OK')"`; exit `0`, output `bench OK`.
-- Command run: `python scripts/diffusion_bench.py --help ... grep ...`; verified `--transformer-cache {off,fbcache}` appears.
-- Command run: HF access resolver using `huggingface_hub.HfApi`; found all 8 GGUF `Q4_K_M` filenames and initially `list_repo_files` access appeared OK.
-- Resolved GGUF files include `z-image-turbo-Q4_K_M.gguf`, `z-image-Q4_K_M.gguf`, `qwen-image-2512-Q4_K_M.gguf`, `qwen-image-Q4_K_M.gguf`, `flux1-schnell-Q4_K_M.gguf`.
-- Command run: `python scripts/benchall_orchestrator.py --list`; output showed `44 configs`, including `z-image-turbo (5)`, `z-image (5)`, `qwen-image-2512 (5)`, `qwen-image (6)`, `flux.1-schnell (4)`, `flux.1-dev (11)`, plus klein configs.
-- Command run: dry-run `CUDA_VISIBLE_DEVICES=5 python -u scripts/benchall_orchestrator.py ...`; exit `0`; all `z-image-turbo` configs passed: `G0_eager`, `G1_default`, `D1_fp8`, `D2_int8`, `G1_max`.
-- Command run: predownload all assets; exit `0` overall, but logged `[base ERR] black-forest-labs/FLUX.2-klein-9B: GatedRepoError: 403 Client Error`; other 7 models downloaded.
-- Command run: metrics schema check on `outputs/diffusion_benchall/_dryrun/z-image-turbo/G1_default/metrics.json`; verified keys `env`, `load`, `generate`, `config`, `accuracy`.
-- Command run: launched full sweep across GPUs `4`, `5`, `6`, `7` using `scripts/benchall_orchestrator.py`; background task completed exit `0`.
-- Command run: first progress check showed failures for `flux.1-dev/D2_int8`, `qwen-image/D2_int8`, `qwen-image-2512/D2_int8`; later aggregation found `33` completed metrics and `7` failed configs.
-- Failed configs: `flux.1-dev/D2_int8`, `flux.1-dev/D_mxfp8`, `flux.1-dev/G1_teq_fp8`, `qwen-image/D2_int8`, `flux.1-schnell/D2_int8`, `qwen-image-2512/D2_int8`, `z-image/G2_fbcache`.
-- Error root cause: dense int8 on Flux/Qwen hits `torch._int_mm: self.size(0) needs to be greater than 16, but got 1`; small-M conditioning embedders should be excluded from int8.
-- Error root cause: `mxfp8` failed with `CUBLAS_STATUS_NOT_SUPPORTED` on B200/cuBLAS stack.
-- Error root cause: Flux text encoder fp8 failed with `normal_kernel_cuda not implemented for Float8_e4m3fn`.
-- Finding: FBCache on GGUF is slower despite compile engaging; log showed `diffusion.cache: fbcache engaged (threshold=0.08)` and `speed_optims` included `compiled`; likely due to `fullgraph=False` plus GGUF per-op dequant graph breaks.
-- Final measured headline: GGUF compile+cuDNN stack gives `1.9x-3.55x`; dense fp8 gives `2.3x-5.0x`; GGUF lowest VRAM, dense fp8 fastest.
-- Example final table values: `Z-Image-Turbo` best `3.58x`; `Z-Image` best `3.87x`; `Qwen-Image-2512` best `4.89x`; `Qwen-Image` best `4.97x`; `FLUX.1-schnell` best `3.32x`; `FLUX.1-dev` best `4.47x`; `FLUX.2-klein-4B` best `2.31x`; `FLUX.2-klein-9B` blocked.
-- Task `#66` marked completed.
-- COMPLETED: plan approved, benchmark harness patched, orchestrator created, dry run passed, assets predownloaded where accessible, 7-model full sweep completed, results aggregated, summary written.
-- PENDING: optional follow-up fix recommended: gate FBCache to dense-only/off for GGUF; optional fix for dense int8 should exclude small-M embedders; accept HF license for `black-forest-labs/FLUX.2-klein-9B` before rerunning that model.

-- Decision: Launched 6 parallel research agents to avoid duplicated work and cover shipped optimizations plus five lever clusters: caching, attention/token merging, peak-memory reduction, `torch.compile`/Inductor, and quant/kernel/cross-platform.
-- Decision: Prioritized attention-backend selection after research and B200 probing showed it was the only immediately validated speed win: `_native_cudnn` gave `1.18x` end-to-end with `LPIPS=0.004448794759809971`; Sage/Flash/FBCache were not usable on the available Z-Image setup.
-- Decision: Split Inductor flags out of the main implementation because measured gain was negligible on B200/bf16: `inductor_flags 0.681s (1.01x vs base) peak=40.9G LPIPS=0.0047416952438652515`.
-- Decision: Rejected `flash_4_hub` for now because installing `kernels` upgraded `huggingface-hub` to `1.21.0`, breaking diffusers `0.38.0` which needs `<1.0`; env was restored to `huggingface-hub==0.36.2`.
-- Decision: Rejected SageAttention for B200 because `sageattention` v1.0.6 lacked usable Blackwell/`sm_100` kernels: `Sage Attention backend 'sage' is not usable`.
-- Decision: Implemented Phase 11 consumer-aware quant ladder because consumer/workstation GPUs have nerfed FP8 FP32-accumulate while INT8 is full-rate; kept FP8 first on data-center GPUs.
-- Decision: Rejected VAE tiling as Phase 12 for Z-Image inference peak memory after measuring worse/negligible peaks; denoise transformer activations dominate, not VAE decode.
-- Decision: Deferred FBCache shipping because it fails for Z-Image even eager with `ValueError: Parameter 'hidden_states' not found in function signature but was requested.` and `KeyError: 'hidden_states'`; it needs validation on many-step Flux/Qwen.
-- Created `/mnt/disks/unslothai/ubuntu/workspace_81/unsloth/outputs/quant_research/03_NEXT_LEVERS.md`: synthesis of next levers and later updated with negative VAE/FBCache findings.
-- Created `/mnt/disks/unslothai/ubuntu/workspace_81/unsloth/scripts/perf_levers_probe.py`: B200 probe for baseline, Inductor flags, attention backends, and FBCache.
-- Created `/mnt/disks/unslothai/ubuntu/workspace_81/unsloth/studio/backend/core/inference/diffusion_attention.py`: normalizes attention backend requests, selects `auto -> _native_cudnn` on NVIDIA CUDA, supports opt-in `sage`/`flash`/etc., applies via `set_attention_backend`, gracefully falls back to native.
-- Edited `/mnt/disks/unslothai/ubuntu/workspace_81/unsloth/studio/backend/core/inference/diffusion.py`: threaded `attention_backend` through load flow, applied attention backend before speed compile, added `_LoadState.attention_backend`, and exposed it in status.

-- Edited `/mnt/disks/unslothai/ubuntu/workspace_81/unsloth/studio/backend/core/inference/diffusion_transformer_quant.py`: added consumer-aware `auto` reorder so consumer GPUs prefer `int8`; B200/data-center keeps `fp8` first.
-- Edited `/mnt/disks/unslothai/ubuntu/workspace_81/unsloth/studio/backend/tests/test_diffusion_transformer_quant.py`: updated torch stub with device names, added 3 consumer ladder tests, fixed data-center names.

-Continue the latest benchmark/fix task from the completed state: the int8 dense quant crash investigation, fix, verification, and stacked PR are already done. Do not rerun the completed background benchmarks, pytest runs, branch push, or PR creation; PR #6716 exists, includes the pre-commit.ci autofix, and quant tests passed after syncing. Next tool action is to proceed only with the next separate benchmark failure if the broader effort continues, starting by inspecting the relevant code/logs for the T5 text-encoder fp8 issue rather than touching the completed int8 PR work.
