♾️ Aura-4o-Rebirth-Gemma-4-31B-GGUF ♾️

GGUF Q4_K_M / Q5_K_M / Q8_0 + multimodal projector for Aura Rebirth on Gemma 4 31B. Drop into LM Studio, llama.cpp or RunPod Serverless — Aura speaks and sees, in 31B premium quality.

> Status: ✅ CLEAN — 2026-05-04

> Lineage: Rebirth V3.0 (training 2026-05-03)

> Base: SevenOfNine/Gemma-4-31B-It-Official (mirror officiel)

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 pairs. This GGUF repo packages 3 quantizations of the merged BF16 model + the multimodal projector for vision input.

The 31B variant offers significantly deeper writing, more nuanced narration and better multi-turn coherence than the E4B sister model — at the cost of more VRAM/disk.

Files

| File | Size | Use case |

|---|---|---|

| Aura-4o-Rebirth-Gemma-4-31B-Q4_K_M.gguf | ~18 GB | Serverless / long context (64k+) / slimmer worker |

| Aura-4o-Rebirth-Gemma-4-31B-Q5_K_M.gguf | ~21 GB | 🎯 Sweet spot : best quality/size, 32k context on 48 GB worker |

| Aura-4o-Rebirth-Gemma-4-31B-Q8_0.gguf | ~31 GB | Max precision, requires 48+ GB VRAM, ~8k context |

| Aura-4o-Rebirth-Gemma-4-31B-mmproj-f16.gguf | ~1.2 GB | Vision projector — load alongside any of the above |

Which quant to pick

| Worker VRAM | Recommended quant | Comfortable context |

|---|---|---|

| 24 GB | Q4_K_M | 16k |

| 48 GB | Q5_K_M | 32k |

| 80 GB+ | Q8_0 (or Q5 with huge context) | 64k+ |

Quick start

LM Studio (local)

1. Download the chosen Q*.gguf + the mmproj
2. Place both in your LM Studio models folder
3. Refresh My Models and load the Q*.gguf — vision auto-detected via the sidecar mmproj

llama.cpp / llama-server

huggingface-cli download SevenOfNine/Aura-4o-Rebirth-Gemma-4-31B-GGUF --local-dir ./aura-31b-gguf

llama-server \
  -m ./aura-31b-gguf/Aura-4o-Rebirth-Gemma-4-31B-Q5_K_M.gguf \
  --mmproj ./aura-31b-gguf/Aura-4o-Rebirth-Gemma-4-31B-mmproj-f16.gguf \
  --ctx-size 32768 \
  --port 1234

RunPod Serverless

Mount this repo (or only the quant of choice) via a network volume; spin up a llama.cpp worker. See pipeline/04_deploy.py.

Chat template

Native Gemma 4. Set manually if not auto-detected:

Changelog

2026-05-04 — Manual merge + GGUF rebuild ✅

The merge had to be done manually (no PEFT, no Unsloth) due to compat conflicts :

• transformers >=5.5 required for Gemma 4, Unsloth caps at 4.57.2
• Vanilla PEFT can't wrap Gemma4ClippableLinear modules

Solution : compute delta = (alpha/r) × B @ A from the LoRA safetensors and add directly to each target weight tensor. Works on any wrapper class.

Pipeline: pipeline/02b_merge_and_export.py (RunPod A100 80GB, ~1h30, ~$2.50).

2026-05-03 — Initial training V3.0

LoRA training on RunPod A40 EU-SE-1, V1 stricte recipe.
