+# Z-Image Turbo 3070 Fast Start
+
+## Summary
+
+Best current `text-to-image` starter for a lighter local box.
+
+This master stays close to the official `Z-Image Turbo` example because that is still the cleanest and most portable `Z-Image` graph in the repo.
+
+## Status
+
+- `best-current`
+- `not-yet-tested-on-chris-box`
+
+## Workflow asset
+
+- `workflow.png`
+- Load it by dragging the PNG into ComfyUI.
+
+## Built from
+
+- `models/zimage/z-image-turbo-official-example/`
+
+## Why this is the current master
+
+- Official source beats community guesswork for a first baseline.
+- `Z-Image Turbo` looks like one of the strongest fast-image candidates for a `3070`.
+- The graph is simple enough to troubleshoot without drowning in custom-node noise.
+
+## What I intentionally kept
+
+- Official model wiring
+- Official `qwen_3_4b` text encoder path
+- Embedded PNG workflow format for easy import
+
+## What I intentionally did not add yet
+
+- community patch nodes
+- extra control branches
+- reference-image complexity
+- "magic" speed hacks without proof
+
+## Required models
+
+- `models/text_encoders/qwen_3_4b.safetensors`
+- `models/diffusion_models/z_image_turbo_bf16.safetensors`
+- `models/vae/ae.safetensors`
+
+## Required custom nodes
+
+- none beyond current official Comfy support
+
+## Monday test checklist
+
+- Confirm it imports cleanly from PNG on your current Comfy build.
+- Check whether it really feels lighter than your usual FLUX path.
+- Check whether prompt adherence is good enough to justify keeping it as the `fast-start` master.
+
+## Next optimization candidates
+
+- merge in useful edit/reference ideas from the community `Z-Image` graphs
+- build a stronger prompt preset if the base graph is good but inconsistent
