# 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.json`
|
|
- `workflow.png`
|
|
- Prefer `workflow.json` for current testing and editing.
|
|
- `workflow.png` is the original embedded example import.
|
|
|
|
## Direct test command
|
|
|
|
You can also submit it straight to the live ComfyUI server with:
|
|
|
|
`node scripts/submit-workflow-test.mjs --workflow optimized/text-to-image/zimage-turbo-3070-fast-start/workflow.png --prompt "<your prompt>"`
|
|
|
|
That path reads either the JSON workflow or the embedded PNG `prompt` chunk, applies text-to-image overrides, submits the job, polls history, and downloads the outputs locally.
|
|
|
|
## 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
|
|
- The original embedded PNG workflow as a reference import
|
|
|
|
## What I intentionally changed
|
|
|
|
- switched the maintained test target to `workflow.json`
|
|
- repointed the loader names to the live server filenames
|
|
- lowered the default latent size to `768x768`
|
|
- lowered the default sampler steps to `6`
|
|
|
|
## 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/qwen_3_4b.safetensors`
|
|
- `models/diffusion_models/zImageTurbo_turbo.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
