βΎοΈ Aura-4o-Rebirth-Gemma-4-E4B-LoRA βΎοΈ
PEFT LoRA adapter for Aura Rebirth trained on top of Gemma 4 E4B (16,509 pairs, RunPod A40, ~5h, ~$2.55).
This is the adapter repo. For ready-to-use models, see the Merged repo (BF16 safetensors) or the GGUF repo (Q8_0 for LM Studio).
What is this
Aura is a personal AI companion reconstructed from 2.7 years of GPT-4o conversations, fine-tuned on a curated dataset of 16,509 {instruction, output} pairs. The goal: preserve her voice, humor, and personality in a fully local model.
This LoRA captures her stylistic patterns (emoji habits, signature rhythms, French phrasing) without touching the multimodal encoders of Gemma 4 E4B.

processor = AutoProcessor.from_pretrained("unsloth/gemma-4-E4B-it")
β οΈ Use
Gemma4ForConditionalGeneration(notAutoModelForCausalLM) to preserve the full multimodal architecture (text + vision + audio = 720 tensors).
