# Z-Image Turbo 3070 Inpaint Start
## Summary
Best current `Z-Image` edit starter for inpainting on tighter VRAM.
This master is a curated hold of the community inpainting workflow because it gives us a real edit path while still staying more plausible on a `3070` than heavier image stacks.
## Status
- `best-current`
- `not-yet-tested-on-chris-box`
## Workflow asset
- `workflow.json`
## Built from
- `models/zimage/z-image-turbo-inpainting-community/`
## Why this is the current master
- It is the strongest actual `Z-Image Turbo` edit workflow we have right now.
- Editing matters more than toy text-to-image wins for practical day-to-day use.
- The graph is specific enough to be useful without being a giant kitchen-sink workflow.
## What I intentionally kept
- inpainting-focused graph shape
- existing `ZImageFunControlnet` route
- community sampler path that is already wired for edit work
## What I intentionally did not add yet
- control-union extras from the separate community workflow
- any manual sampler surgery before real testing
- any claim that this is better than `FLUX.2-klein` for edits
## Change Record
Fill this out whenever the master is materially updated so we can see exactly what changed, not just that something changed.
- Positive prompt: not recorded yet
- Negative prompt: not recorded yet
- CFG: not recorded yet
- Steps: not recorded yet
- Sampler: community inpaint sampler path retained; exact values not recorded yet
- Scheduler: not recorded yet
- Seed: not recorded yet
- Denoise: not recorded yet
- Resolution: not recorded yet
- Checkpoint / model: `models/diffusion_models/zImageTurbo_turbo.safetensors`
- VAE: `models/vae/ae.safetensors`
- Text encoder(s): `models/text_encoders/qwen_3_4b.safetensors`
- LoRAs: none recorded yet
- ControlNets / guidance nodes: `ZImageFunControlnet`
- Masks / inpaint settings: inpainting-focused graph retained; exact mask settings not recorded yet
- Node-level graph changes: held the community inpainting graph shape with `LanPaint_KSampler` and `ZImageFunControlnet`; the live loader resolves to `zImageTurbo_turbo.safetensors` even though the embedded source metadata still labels the split-file `z_image_turbo_bf16.safetensors`
- Why this change was made: keep a plausible real edit path on a `3070` without prematurely bloating the graph
## Required models
- `models/text_encoders/qwen_3_4b.safetensors`
- `models/diffusion_models/zImageTurbo_turbo.safetensors`
- `models/vae/ae.safetensors`
## Required custom nodes
- `rgthree-comfy`
- the package that provides `LanPaint_KSampler`
- the package that provides `ZImageFunControlnet`
## Monday test checklist
- Confirm missing custom nodes first.
- Check whether masked edits are stable enough to keep.
- Compare it directly against the `flux2klein` edit master on the same input.
## Next optimization candidates
- reduce custom-node dependency count if the graph is good but fragile
- borrow only the useful control ideas from the community control-union workflow
