Krea2 Character LoRA Collection

A collection of 84 character LoRAs for the KREA2 base AND turbo model, each paired with a persona .md file describing the character's stable facial features, variable appearance, and expressions.

Every LoRA ships as <Name>_KREA2.safetensors alongside <Name>_KREA2.md inside its own folder under Characters/.

Updates

Repository restructure

• All characters moved under a single Characters/ directory (one folder per character containing the .safetensors, the persona .md, and the training captions).
• A new Pruned_Comparison folder was added with one preview image per character (see below).

Dynamic re-rank + block pruning

Every LoRA was re-ranked with dynamic sv_fro SVD (retention 0.998, max rank 16) and block-pruned by dropping the 8 lowest-impact transformer blocks (blocks 1-8, ~3% of delta energy).

Retrained character

• Jung Ho-yeon (Ho-yeon) was retrained on a new dataset, then re-ranked and pruned like the others.

Fully automated pipeline

This repository - dataset, training, and upload - was produced end-to-end by an autonomous Hermes Agent (served by the Kimi K3 model) from a natural-language request. No manual review gates anywhere in the loop:

1. Scraping - automated image collection per character from web photo pools.
2. Cropping & curation - face/head detection Ultralytics Yolo and crop, with a hard content filter (No AI generated images, correct subject only, sharpness threshold).
3. Aesthetic gating - every candidate image scored by a discriminator built on the ERNIE aesthetic image scorer; low scorers rejected automatically with a hard pass/fail threshold.
4. Captioning - datasets captioned with Gemma-4 26B (abliterated) vision MTP for unrestricted, descriptive captions, fast (1.2s/i).
5. Persona synthesis - each <Name>_KREA2.md generated from caption trait-analysis (facial features, range of expressions).
6. Infrastructure - training pods created, configured, monitored, and torn down automatically via the RunPod API (MCP).
7. Training - LoRAs trained on pods with Ostris AI-Toolkit with user predefined settings.
8. Publishing - weights and persona files uploaded to this repo by the agent.

Known limitations

• Trained for likeness; style flexibility depends on your prompt and sampler settings.
