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
