Logen Desktop Studio Windows & Linux x64

Own the darkroom,
not the cloud tab.

TitanXT builds local-first creative software that runs directly on your GPU. Generate studio-grade imagery with FLUX.1-schnell and ComfyUI pipelines inside a self-healing desktop studio—with zero per-image fees, zero cloud queues, and zero third-party prompt logging.

01 / ARCHITECTURAL THESIS

Why working creatives are leaving rented cloud queues.

Cloud generators meter your curiosity by the credit, store every client concept on remote servers, and silently swap model behavior mid-project. Running locally on your own GPU changes the economics and the craft.

Rented Cloud Subscriptions

Metered tabs & shared queues

  • Recurring £20–£60/month overhead £240 to £720 every year whether you are in active production or between client briefs.
  • Prompts & client drafts on third-party servers Every concept, product prototype, and unpublished campaign asset leaves your machine.
  • Unannounced model drift Cloud endpoints update weights behind the scenes, breaking repeatable look-development seeds.
  • Peak-hour throttling & content filters Fast-hour burn rates and opaque moderation gates interrupt studio deadlines.
TitanXT Local Architecture (Logen)

Your GPU. Your weights. Your disk.

  • Free tier forever · Optional £49 one-time Pro Generate with FLUX.1-schnell and SD 1.5 at £0, or unlock Batch mode, 4K upscaling, and custom workflows once.
  • Complete creative confidentiality Prompts and rendered pixels stay inside your local project folders (Documents/Logen/).
  • Deterministic checkpoints & seeds Pin exact GGUF/Safetensors weights, sampler schedules, and seeds for repeatable client revisions.
  • Zero node-graph spaghetti required Logen installs and supervises ComfyUI and Ollama automatically—giving you a clean studio UI instead of broken Python venvs.

SELF-HEALING RUNTIME // OLLAMA + COMFYUI

Auto-starts local engines & diagnoses issues in one click.

Raw local AI tools fail silently when background services stop or VRAM fills up. Logen automatically starts ollama serve when you submit a chat prompt and surfaces plain-English recovery actions if a model is missing or memory runs tight.

AUTO-RECOVERY Ollama service was offline — spawned headless background engine and restored prompt. ✓ Online

HARDWARE-AWARE MODEL MANAGER

Know what fits your GPU before you download.

Logen inspects your graphics card and tags every model with live VRAM fit badges and license metadata so you never waste bandwidth on weights your card cannot run.

PROJECT GALLERY & 1:1 LIGHTBOX

Inspect at true 1:1 pixel resolution or jump back to the prompt.

Filter your gallery by project folder, inspect grain at 100%–400% zoom, navigate variations with arrow keys, copy the exact prompt, or reopen the originating chat thread in one click.
