AnimaForge
Free, local, one-click LoRA trainer built only for Anima. Point it at a folder. Name it. Forge.
Training a LoRA shouldn't mean an evening lost in Kohya's wall of knobs. AnimaForge is a free Windows app that does the whole run from one screen: pick your image folder, name the LoRA, hit Train. It auto-captions (WD14 tags + JoyCaption descriptions), calculates sane step counts for your dataset size, and trains with settings hand-tuned for one model — Anima. That focus is the whole point.
You watch it learn. Preview images render every epoch while training runs. Flip on Compare epochs to see them side by side, spot the earliest epoch that already nails your character, and stop right there — no over-training guesswork, no re-runs. Stopped too soon or crashed? Resume from the last checkpoint.
It has opinions, so you don't need any. Pick a preset — Person, Object / Concept, or Style — and the subject handling, optimizer, network size, and step budget are set. Power users can save their own presets, switch optimizers (Prodigy auto-LR or classic AdamW8bit), and preview the exact training config before launch. Guard rails catch the classics before they burn a run: empty captions (one-click fix), low VRAM, even duplicate images hiding in your dataset.
It finishes the job. One click copies the trained LoRA into your Forge or ComfyUI models folder — with the trigger word baked into the filename, so anyone you share it with knows exactly what to type. A batch queue captions and trains multiple LoRAs unattended, and survives a restart.
Runs on your machine. Your images, captions, and LoRAs never leave your computer. No subscriptions, no queues, no uploads.
WHAT'S NEW — v2.9.3
• Stray USE_LIBUV in your own Windows environment? Fix it without leaving AnimaForge — Setup → Training Environment adds a checkbox that forces AnimaForge's setting even when your environment already has one, plus a button that clears it from Windows outright. No more manual System Properties surgery
• See exactly what's in play — a live status line in Setup shows the effective USE_LIBUV and where it's coming from, so you're never guessing whether the fix applies to you
• Reset Training Environment — one click re-verifies PyTorch from scratch when something about your setup looks stale, without losing your last known-good result unless the fresh check genuinely can't confirm it
• Clear now tells you whether it worked — success or failure is logged right there instead of the button just going grey

WHAT YOU'LL NEED
• Windows + NVIDIA GPU (CUDA) — includes RTX 50-series. No CPU/AMD path.
• ~16 GB VRAM comfortable; low-VRAM mode reaches smaller cards (8 GB practical floor).
• The three Anima files (Setup auto-detects them): DiT checkpoint, Qwen3 text encoder, Qwen-Image VAE — from Hugging Face circlestone-labs/Anima.

install.bat (one-time — builds a self-contained .venv with the full stack), then launch.bat.
100% free and open source (MIT). Built for the Anima community. Forge something great.

VERSION DATE WHAT CHANGED
------- ---------- ------------------------------------------------------------
v2.7 2026-07-10 LM Studio removed entirely — captioning is fully local (WD14
+ JoyCaption, merged mechanically), no external LLM server
needed or contacted · fixes the bug where some .nl captions
randomly came out as raw tags instead of prose · Combine now
de-dupes and tidies booru tags with no model in the loop ·
Describe gains "Redo all" — re-caption everything with a
live per-image stream · steadier shutdown
v2.6 2026-07-10 Optional "check for updates at startup" (Setup) notifies you
when a newer build has landed · the check runs safely off the
UI thread · icon/caption fixes
v2.5 2026-07-09 Captioning never overwrites existing caption files without
asking (keep / overwrite / set it once) · caption runs resume
where they stopped, and a killed training run comes back even
if you moved its folder · the batch queue captions each set
then trains it, settling every conflict up front · Add to
Batch is back on the front page; Restart from Top re-runs a
finished queue · find/replace rules fix misgendering and ban
tags · re-running Auto-Tag no longer duplicates every tag
v2.3 2026-07-06 Fixes a "division by zero" crash when aspect-ratio bucketing
met an image with a side under 64 px (it killed the run at
exit code 1) — now caught before launch with a one-click fix,
and auto-handled on unattended/batch runs · corrected
epoch/preview step math · live sample-preview UI overhaul
v2.2 2026-07-04 Pick your own UI font (Setup → App Defaults): forge faces,
system font, or any installed font · fixes non-Latin
readability (CJK, Cyrillic) · applies live, no restart ·
default look unchanged
v2.1 2026-07-03 Project autosave under the LoRA name at both caption
milestones · Restore captions from Saved Sets · low-VRAM
warning auto-continues after 10 s on unattended runs ·

v2.0 2026-07-02 New brand badge across the app · preset picker shows each
intent's step math · one launch point (Options configures,
the front launches) · config preview beside Start ·
monospace version digits · spacing polish
v1.9 2026-07-02 Training presets (Person/Object/Style + save your own) ·

analog Epoch/Loss/Speed/ETA dials · optimizer presets
(Prodigy / AdamW8bit) · RTX 50-series support · empty-caption
guard with one-click fix · config preview · per-epoch
preview schedule on the progress bar
