The app

This is what you install

One desktop app. Chat, image, and video each have their own screen. Models stay on the machine you paid for.

Hadalyx private chat screen with a local model selected.

Chat

Private chat on this computer. Messages go to the local engine, not a cloud inbox.

Hadalyx creator screen for generating images on the local GPU.

Images

Flux and SDXL runtimes on your GPU. Describe a scene, generate it here.

Hadalyx video screen for local text-to-video generation.

Video

Short local clips on high-VRAM cards. Preview first, then render.

Sample image generated locally with Hadalyx: a silver robot on a purple studio pedestal.

Made on a local GPU

FLUX smoke test from the Hadalyx Creator stack. This is the kind of output the image workflow is built to produce.

Why buy once

Own the stack. Stop renting it.

Cloud AI bills every month and takes your prompts off-site. Hadalyx is a one-time package that runs on hardware you already own.

Wait for the block

The download email goes out after the payment is included in a Bitcoin block. Check spam if it is not in your inbox.

Install on this PC

The installer sets up the app and models for your NVIDIA GPU. After that, supported work can run offline.

What you get

Built to stay on your machine

Works offline after install

Installed models keep working without the internet. First-time downloads still need a connection.

You set the local rules

Open-weight models run as their authors ship them. Content policy is local, plus each model’s license.

Lifetime update access

Come back to the download portal for tested config and model updates. No extra monthly fee.

Human support

Installer, GPU, and library help. Ultimate and Video include one year of priority support.

Guided installer

Scripts handle the dependency and CUDA setup so you are not compiling a stack by hand.

Speed follows your GPU

Tokens and image times scale with VRAM and the card you already have. Profiles ship per bundle.

Hardware

What you need

Comfortable minimums. More VRAM is faster. This release is Windows 11 + NVIDIA only.

Validated on one Windows / NVIDIA rig

Windows 11 build 26100, Ryzen 9 5900X, 64 GB RAM, and GeForce RTX 5060 8 GB completed chat, 512×512 FLUX image, small-format Wan video, checksum, and four-edition installer smoke tests.

That is evidence for this exact configuration — not a guarantee for every NVIDIA GPU. Comfortable tier minimums below still apply. AMD, Intel GPU, clean-machine, and code-signing checks remain pending.
