feat(z-image): add Z-Image Base (undistilled) model variant support by Pfannkuchensack · Pull Request #8799 · invoke-ai/InvokeAI

Pfannkuchensack · 2026-01-28T20:42:50Z

Summary

Add ZImageVariantType enum with 'turbo' and 'zbase' variants
Auto-detect variant on import via scheduler_config.json shift value (3.0=turbo, 6.0=zbase)
Add database migration to populate variant field for existing Z-Image models
Re-add LCM scheduler with variant-aware filtering (LCM hidden for zbase)
Auto-reset scheduler to Euler when switching to zbase model if LCM selected
Update frontend to show/hide LCM option based on model variant
Add toast notification when scheduler is auto-reset

Z-Image Base models are undistilled and require more steps (28-50) with higher guidance (3.0-5.0), while Z-Image Turbo is distilled for ~8 steps with CFG 1.0. LCM scheduler only works with distilled (Turbo) models.

Only Tested with Diffusers version of the Model.

Related Issues / Discussions

Adds full support for Z-Image Base (undistilled) models alongside the existing Z-Image Turbo support.

QA Instructions

Import a Z-Image Turbo model - Verify variant is detected as "turbo"
Import a Z-Image Base model - Verify variant is detected as "zbase" (shift value 6.0 in scheduler_config.json)
Select Z-Image Turbo model - Verify LCM scheduler option is available
Select Z-Image Base model - Verify LCM scheduler option is hidden (only Euler and Heun shown)
With LCM selected, switch from Turbo to Base - Verify scheduler auto-resets to Euler with toast notification
Edit model in Model Manager - Verify variant field is editable for Z-Image models

Merge Plan

Database migration (migration_26) adds variant field to existing Z-Image models. Safe to merge anytime.

Issues involving Z-Image Turbo support

I found a couple of problems with support for Z-Image Turbo.

Problem 1

After pulling the PR and restarting the backend, I'm getting config validation errors on previously-installed Z-Image Turbo models, and they vanish from the model manager.

Here is the type of error message that appears during startup:

Problem 2

Installing a new ZiT model (in this case z_image_turbo-Q4_K.gguf) fails with a similar pydantic validation error:

I can confirm that Z-Image Base (Diffusers):

Installs correctly
Variant is recognized correctly as "Z-Image Base"
Steps and CFG default to appropriate values
txt2img working
img2img working
Inpaint working
Outpaint working
Only Heun and Euler schedulers are shown
❌ ZiT LoRAs are working with ZiB -- Produces a fractured image
❌ Standalone denoiser .safetensors version installs -- Produces a pydantic validation error

I was unable to test whether the LCM scheduler reappears when a turbo model is installed due to the earlier issues with turbo model validation errors.

Pfannkuchensack · 2026-02-01T00:31:20Z

ZiT LoRAs are working with ZiB -- Produces a fractured image

That is to be expected

Standalone denoiser .safetensors version installs -- Produces a pydantic validation error

i will take a look

The zimage Turbo models should be getting a variant with the migration. Do you have the startup log?

See Problem 1 and Problem 2 in the earlier comment for the error log startup messages. Let me know if you need more.

I reported the same issue on Discord the other day; I should have posted it here in the first place. Here is a link to the log I pasted in Discord.
