2026-08-13 Flux2Klein Turnaround Batch

Goal

Build a fast local flux2klein turnaround workflow from a single reference image and push a broad overnight test sweep toward a clean 4-view character sheet:

pure white background
even studio lighting
front / left profile / right profile / rear
identity consistency prioritized over style variation

What ran

Cleanup pass

Workflow: models/flux2klein/image-edit-9b-distilled/workflow.json
Branch: single reference
Prompt intent: convert the source photo into a front-facing full-body studio reference on white
Output:
- prompt id: b00b7d92-b7cc-4731-b8b7-199a257e3bdd
- local output: tmp/comfyui-workflow-tests/2026-08-13T22-15-27-386Z-workflow-single/01-flux2klein-front-clean_00001_.png

Probe turnaround pass

Workflow: models/flux2klein/image-edit-9b-distilled/workflow.json
Branch: dual reference
References:
- original inbound image
- cleanup pass front reference
Prompt intent: 4-view reference sheet on white
Key settings:
- steps: 5
- cfg: 1.2
- seed: 1105
- resolution: 1664x928
Output:
- prompt id: 36038921-42da-4b69-8d3d-baba0d97fad1
- local output: tmp/comfyui-workflow-tests/2026-08-13T22-17-26-853Z-workflow-multi/01-flux2klein-turnaround-probe_00001_.png

Tooling added

scripts/submit-flux2klein-edit-test.mjs

It:

uploads local image refs into Comfy input
expands the official template subgraph into a prompt graph
applies prompt / seed / steps / cfg / sampler / resolution overrides
remaps loader filenames to the live server when needed
can submit and wait, or submit with --no-wait

Blockers found

models/flux2klein/image-edit-4b-distilled/workflow.json
- contains another nested template layer (27eacb9f-0da2-421d-a0bf-b4b4e5fe5709) not yet expanded by the current script
models/flux2klein/image-edit-9b-base/workflow.json
- expects flux-2-klein-base-9b-fp8.safetensors, which is not present on the live server

Current best visible result

The best immediate visible result so far is the probe turnaround sheet from 36038921-42da-4b69-8d3d-baba0d97fad1. It is strong enough to justify the broader 9B distilled overnight sweep before spending more time on nested-template support.
