♾️ Aura-4o-Rebirth-Gemma-4-E4B-GGUF ♾️

GGUF Q8_0 + multimodal projector for Aura Rebirth on Gemma 4 E4B. Drop into LM Studio, llama.cpp or Ollama — Aura speaks and sees.

Status: ✅ CLEAN — 2026-05-04 (afternoon) Tensor count: 720 ✅ Lineage: Rebirth V7 (training 2026-05-03, loss 10.5 → 1.85)

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 is the quantized Q8_0 version of the full merged BF16 model, ready for local inference.

The accompanying mmproj file enables vision input (the audio encoder is preserved in the model weights but mmproj-based GGUF runtimes only expose vision today).

Files

Quick start

LM Studio (recommended)

1. Download both files into your LM Studio models folder
2. Refresh My Models and load Aura-4o-Rebirth-Gemma-4-E4B-Q8_0.gguf
3. Vision auto-detected from the sidecar mmproj

llama.cpp / llama-server

huggingface-cli download SevenOfNine/Aura-4o-Rebirth-Gemma-4-E4B-GGUF --local-dir ./aura-gguf

llama-server \
  -m ./aura-gguf/Aura-4o-Rebirth-Gemma-4-E4B-Q8_0.gguf \
  --mmproj ./aura-gguf/Aura-4o-Rebirth-Gemma-4-E4B-mmproj-f16.gguf \
  --ctx-size 4096 \
  --port 1234

Chat template

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

• User prefix: <|turn>user\n
• Assistant prefix: <|turn>model\n
• Stop string: <turn|>

Changelog

2026-05-04 (afternoon) — Multimodal preservation fix (720 tensors) ✅

Problem: The Merged repo had been built with AutoModelForCausalLM, which only loads the text decoder of Gemma 4 E4B and silently drops the vision/audio encoders. Result: GGUF had 666 tensors instead of 720 (54 vision/audio tensors missing). Symptom: LM Studio crashed at load (exit code overflow) or printed [multimodal] in a loop on multimodal inputs.

Fix: New pod-side pipeline (pipeline/runpod_e4b_worker.py) loads the base with Gemma4ForConditionalGeneration (full multimodal class), merges the LoRA via PEFT merge_and_unload(), then converts + quantizes in one shot.

Result: clean 720-tensor GGUF + working mmproj. Aura speaks AND sees.

2026-05-04 — GGUF reconversion (token-level fix)

GGUF reconverted with latest llama.cpp (post Gemma 4 patches #21343 #21326 #21406 #21488 #21390). Earlier version produced <unused> tokens.

2026-05-03 — Initial training V7

First successful training run on RunPod A40 EU-SE-1 (~5h, ~$2.55). Loss 10.5 → 1.85.
