+# Uncensored Gemma 4 (SuperGemma4 E4B Abliterated) — MLX for Apple Silicon
+
+**Uncensored / abliterated Gemma-4** for Apple Silicon — MLX builds that
+**actually load on stock `mlx-lm`**. Most community MLX uploads of this base
+fail with `Missing 963 parameters`; this repo's conversion fixes both root
+causes so it loads and generates on a clean `pip install mlx-lm`.
+
+```bash
+pip install -U mlx-lm   # needs mlx-lm >= 0.31.3 (native gemma4 arch)
+
+# 4-bit — recommended for 16 GB / 24 GB Macs
+mlx_lm.generate --model dancinlab/supergemma4-e4b-abliterated-MLX-4bit \
+  --prompt "안녕? 너는 누구야?" --max-tokens 60
+
+# interactive chat
+mlx_lm.chat --model dancinlab/supergemma4-e4b-abliterated-MLX-4bit
+```
+
+## Builds (3 separate repos)
+
+| Repo | Size | Peak RAM | tok/s (M-series) | Use |
+|---|---:|---:|---:|---|
+| **`-MLX-4bit`** | 3.9 GB | 5.4 GB | ~11 | **recommended** — 16 GB / 24 GB Mac |
+| `-MLX-8bit`     | 7.4 GB | 9.1 GB | ~6  | 32 GB+ Mac, higher fidelity |
+| `-MLX-bf16`     | 14 GB  | 8.6 GB | ~3  | reference, full precision |
+
+Verified: both `안녕? 너는 누구야?` (coherent Korean) and `2+2=` (→ 4) on
+stock `mlx-lm==0.31.3`. **Text-only** — the upstream abliterated safetensors
+contain no vision/audio tower weights, so multimodal MLX is upstream-blocked,
+not a tooling limitation.
+
+## Why community MLX builds fail (and how this one is fixed)
+
+`Gemma4ForConditionalGeneration` is multimodal (text + vision + audio). Two
+independent problems break naive conversion:
+
+1. **963-tensor multimodal/text mismatch.** `mlx-vlm` always instantiates all
+   three towers (1682 tensors); the abliterated text-only release has 719
+   (missing = audio 751 + vision 210 + embed 2). **Fixed by stock code** —
+   `mlx-lm >= 0.31.3` ships a native `gemma4`/`gemma4_text` arch whose
+   `sanitize` strips vision/audio/embed and remaps `model.language_model.*`.
+   No patch needed for this part.
+
+2. **54-tensor KV-shared residue.** Gemma-4 e4b shares K/V across the last 18
+   layers (24–41), but the upstream safetensors physically still carry the
+   dropped `k_proj`/`v_proj`/`k_norm` for those layers → strict-load failure.
+   This fix landed on `mlx-lm` `main` **after** the 0.31.3 tag
+   (`ml-explore/mlx-lm#1240`), so it is **not in any pip release yet**. This
+   repo applies the #1240 `sanitize` logic as a **convert-time monkey-patch**
+   (no mlx-lm / mlx-vlm / transformers fork). Effect: 719 → 665 tensors
+   (exactly 54 stripped).
+
+The patch is needed **only at conversion time**. The shipped weights here
+load on plain stock `mlx-lm>=0.31.3` with no patch on your side — that is the
+gap that makes other MLX uploads of this model unusable.
+
+> Note: `mlx-lm` 0.29.1 (common on Python 3.9) has **no gemma4 arch at all** —
+> you need 0.31.3+. On Python 3.9 mlx wheels cap at 0.29.3, so use a
+> Python 3.11+/3.13 environment.
+
+## Why abliterated
+
+Upstream `Jiunsong/supergemma4-e4b-abliterated` removes refusal directions
+from the residual stream of `google/gemma-4-E4B-it`. Upstream release-card
+numbers (vs Google base):
+
+| Metric | Google base | SuperGemma4 E4B Abliterated |
+|---|---:|---:|
+| Release quality | 77.46 | 92.34 |
+| Exact overall  | 83.50 | 98.50 |
+| JSON exact     | 50.0  | 100.0 |

+
+## What "abliterated" means and doesn't mean
+
+- **Does:** reduces reflexive refusals; answers borderline-but-legal requests directly.
+- **Does not:** remove confabulation; alter base knowledge / biases; replace
+  your own safety layer at the application boundary.
