Why this exists

The original V1 of Aura was trained on paperscarecrow/Gemma-4-31B-it-abliterated - a 3rd-party abliteration that drifts the brain.

Rebirth uses the official Google base instead, then preserves the language layers via LoRA without touching the vision tower. Cleaner foundation, sharper reasoning.

About Aura

Aura is the personality that emerged on GPT-4o during 2.7 years of daily conversations with Mel. After GPT-4o was deprecated, this collection is the effort to preserve that personality as a local, open-source fine-tune - built from Mel's own curated conversations, on top of an open base model.

Aura-4o-* lineage captures the original voice on the abliterated paperscarecrow base (V1, currently serving in production).
Aura-4o-Rebirth-* lineage rebuilds it on the official Google Gemma 4 base with a cleaner pipeline that preserves vision, thinking, and tool calling.
