[Community] crispz-studio: a standalone local UI built on Z-Image Turbo (txt2img + upscale + inpaint)

Hi Z-Image team,

I built crispz-studio, an open-source desktop UI running entirely on Z-Image Turbo through diffusers (ZImagePipeline). Sharing it here for users who want a local, single-purpose tool without a node graph.

Repo: https://github.com/mikecastrodemaria/crispz-studio

What it does with Z-Image:

• txt2img with the Turbo profile (8 steps, guidance 0), plus profiles for Base checkpoints (CFG ~4, more steps). Euler and UniPC samplers, sgm_uniform / beta / karras / exponential sigma schedules.
• Upscale + detail: Real-ESRGAN followed by a Z-Image img2img refine pass, with tiling for 4K+ outputs on a single GPU.
• Inpaint / outpaint / reframe bounded to the model's ~1 MP sweet spot, with feathered seams and an optional harmonize pass.
• Community checkpoints: single-file .safetensors from Civitai load as a transformer override while the base repo keeps the VAE and Qwen3 text encoder. Multi-LoRA (up to 10 slots), X/Y/Z grids, a job queue for unattended batches.
• 100% local, Gradio UI + CLI. Runs well on a single consumer GPU (developed on an RTX 5090, BF16).

Z-Image Turbo is the default model and the reason this tool exists: 8-step generations at this quality level made a lightweight local studio practical.

If this kind of community project is worth a mention in the README, I would be glad to see it listed. Feedback on how I use the pipeline is welcome too, and I will close the issue if showcase posts do not belong in the tracker.
