Package

What this package does

From the documents of veizik-flux-1.0.5-linux-x86_64.vzpack (release v1.0.5).

FLUX.1 text to image on NVIDIA GPUs, as a self-contained native engine — no Python, no CUDA toolkit. Eight variants: FLUX.1-dev (12B) and FLUX.1-schnell, plus Kontext, Krea and the Tools set (Fill, Depth, Canny, Redux).
Renders 1024×1024 images with veizik run <key> "prompt" --out out.png (options: --steps, --seed, --mode [quality / balanced / efficient / compact / low-memory / fast / ultrafast], --weights). The Tools variants condition on an input image via --image (Fill also takes --mask).
Per-architecture cubin for every supported GPU, with no compile step at render time; device-bound activation; a v1 provenance mark on every image.
Two licences, and they differ: FLUX.1-schnell is Apache-2.0; the dev variants are under the FLUX.1 Non-Commercial Licence from Black Forest Labs — commercial work needs a separate licence from them. Veizik neither redistributes nor relicenses the weights, which you supply.

Guide

How to run it

Get the veizik command

Get the veizik command for Linux x86-64:

veizik

$ curl -fsSL https://veizik.com/install.sh | sh
# if the installer asks you to put ~/.local/bin on your PATH
$ export PATH="$HOME/.local/bin:$PATH"

Install the model engine
This model is in veizik-flux-1.0.5-linux-x86_64.vzpack. veizik install downloads it from its GitHub release and refuses it unless its SHA-256 matches the one on the download page.
install
```
# accepted names: flux or a full model key (flux1dev, fluxschnell, fluxkrea, fluxcanny, fluxdepth, fluxfill, fluxkontext, fluxredux); any case
$ veizik install flux
```

Activate this device

Approve the machine once; it receives a licence bound to it.

activate

$ veizik activate
# without a browser (SSH, servers): create a key + CLI password on your account page, then:
$ veizik activate --key KEY --password-stdin

Run it

The first commands for this model, as the package’s own documents give them.

run

# FLUX.1 weights are user-supplied from Black Forest Labs, and two licences apply:
#   FLUX.1-schnell — Apache-2.0, no conditions (public, ungated).
#   flux1dev + the Krea / Canny / Depth / Fill / Kontext / Redux variants — FLUX.1 [dev] under the FLUX.1 Non-Commercial Licence: accept it at Black Forest Labs (Hugging Face gated), and commercial use needs a separate licence from them.
$ veizik hf login # once, for the gated dev checkpoints
# text to image:
$ veizik pull flux1dev
$ veizik run flux1dev "<your prompt>" --seed 42 --steps 8 --out out.png
$ veizik pull fluxschnell # Apache-2.0, ungated, 4-step
$ veizik run fluxschnell "<your prompt>" --steps 4 --out out.png
$ veizik run fluxkrea "<your prompt>" --out out.png
# image-conditioned (the Tools set takes an input image):
$ veizik run fluxcanny "<your prompt>" --image edge.png --out out.png # Canny edges
$ veizik run fluxdepth "<your prompt>" --image depth_src.png --out out.png # depth map
$ veizik run fluxfill "<your prompt>" --image base.png --mask mask.png --out out.png # inpaint / outpaint
$ veizik run fluxkontext "<your prompt>" --image input.png --out out.png # instructed edit
$ veizik run fluxredux "<your prompt>" --image ref.png --out out.png # variation
# options: --out --seed --steps --mode (quality | balanced | efficient | compact | low-memory | fast | ultrafast) --weights. Bring your own weights with --weights DIR (or VZ_WEIGHTS) to skip pull. run does NOT auto-download — pull is the download step. Every image carries a v1 provenance mark.

Support

Where it runs.

Evidence and availability are separate: a verified device is not a download, and an available model is not verified on every device.

“Verified” means this family ran end to end on that exact device, on a published build. Architecture membership never upgrades a device to verified.

Licence

Weights and terms

FLUX.1-schnell is Apache-2.0 with no conditions. The other seven variants — dev, Kontext, Krea, and the Tools set (Fill, Depth, Canny, Redux) — are FLUX.1 [dev] models under the FLUX.1 Non-Commercial Licence: commercial work needs a separate licence from Black Forest Labs. Veizik neither redistributes nor relicenses any of them.
