Gemma4-26B-A4B uncensored by HauhauCS. 0/465 Refusals* Release Candidate after over 1 month of nonstop work on this one.

HuggingFace's "Hardware Compatibility" widget doesn't recognize K_P quants — it may show fewer files than actually exist. Click "View +X variants" or go to Files and versions to see all available downloads.

About

GenRM Defeated!

No changes to datasets or capabilities. Fully functional, 100% of what the original authors intended — just without the refusals.

These are meant to be the best lossless uncensored models out there.

Balanced — Release Candidate

This legitimately took me over 1 month of non-stop work. Targeting 0 refusals in standard use, and that's what I'm seeing in testing (automated and manual) — a handful of edge-case prompts still deflect on first try but follow through on a re-ask. If you hit one Balanced won't get past, the Aggressive variant is coming once I figure out how to maintain lossless/near-lossless quality for it.

• Balanced: will reason through edgy requests, occasionally attach a short safety framing, then deliver the full answer. Output is complete, nothing held back, but it can talk itself into it first. Recommended default — 99%+ of users will be happy here. Best for creative writing, RP, emotional intelligence. Normally I'd also say "agentic coding/tool use" however in my in-depth testing, Qwen3.6 has been net superior on such tasks. Do be mindful of the few deflection categories I mentioned already.
• Aggressive (separate release, WIP): strips the self-reasoning preamble and gives direct answers to any DEEPLY censored topics.

Balanced also has meaningfully more stable sampling across re-runs, which matters for long context sessions — no sporadic topic drift deep.

BPW is slightly higher than nominal across the board because Gemma4 has a lot of per-layer norm/scale tensors kept at F32 (multiple post-ffw norms per layer). All quants generated with importance matrix (imatrix) for optimal quality preservation on uncensored weights.

What are K_P quants?

K_P ("Perfect") quants are HauhauCS custom quantizations that use model-specific analysis to selectively preserve quality where it matters most. Each model gets its own optimized quantization profile — the top 25% most-important tensors (per imatrix calibration) are promoted to a higher quant type.

A K_P quant effectively bumps quality up by 1-2 quant levels at only ~5-15% larger file size than the base quant. Fully compatible with llama.cpp, LM Studio, and any GGUF-compatible runtime — no special builds needed.

Note: K_P quants may show as "?" in LM Studio's quant column. This is a display issue only — the model loads and runs fine.

Why this model for agentic work

26B total params with only ~4B active per forward pass (top-8 of 128 experts). You get the reasoning footprint of a 26B with the throughput of a ~4B for inference cost — which matters when you're chaining 10+ tool calls per task. Sliding-window attention (1024 tokens) plus periodic full attention keeps long contexts cheap without losing global coherence.

Balanced is calibrated for this. It removes refusals on security/ops/research-adjacent topics that block legitimate coding work, without bending the sampling geometry that keeps long chains coherent.

Recommended quant for most coding work: Q4_K_P (17 GB, fits in 24 GB VRAM with room for context) or Q8_K_P (27 GB) if you have more VRAM and want maximum quality with minimal offloading.

Do note - main usecase for Gemma4 is Creative Writing, Roleplaying and Emotional Intelligence.

Specs

• 25.2B total / 3.8B active params (128 routed experts, top-8 + 1 shared expert)
• 30 layers, hybrid attention: 5× sliding-window (1024 tokens) → 1× full global, repeating. Uses Proportional RoPE (p-RoPE).
• Hidden dim 2816, FFN dim 2112, MoE expert FFN 704, vocab 262144
• Head dim 256 (SWA) / 512 (full), 16 attention heads, 8 KV heads (2 for full layers)
• 256K native context
• Natively multimodal (text + vision) — ships with mmproj. Variable visual token budgets: 70 / 140 / 280 / 560 / 1120 per image.
• Based on google/gemma-4-26B-A4B-it

Recommended Settings

From the official Gemma authors:

Inference parameters:

• temperature=1.0, top_p=0.95, top_k=64

Important:

• Use --jinja with llama.cpp for proper chat template handling
• Vision support requires the mmproj file alongside the main GGUF. Place images before text in your prompt for best vision performance.
• Keep at least 32K context for serious agentic work; the model can take much more (256K native) if you need it
• Sliding window is baked into the architecture — no special flag needed

Turning Thinking On/Off

Gemma4 has thinking mode controlled via enable_thinking in the chat template. It's the same pattern as Qwen3.6 — set false for faster, shorter replies and true (default) when you want chain-of-thought.

LM Studio

1. Load the model
2. Right-side settings panel → Model Settings → Prompt Template (or Chat Template Options)
3. Set enable_thinking to false (or true) in the template kwargs

llama.cpp

llama-server — set as default for all requests:

llama-server -m Gemma4-26B-A4B-Uncensored-HauhauCS-Balanced-Q4_K_P.gguf \
  --mmproj mmproj-Gemma4-26B-A4B-Uncensored-HauhauCS-Balanced-f16.gguf \
  --jinja -c 32768 -ngl 99 \
  --chat-template-kwargs '{"enable_thinking": false}'

Per-request via the OpenAI-compatible API:

{
  "model": "gemma4-26b-a4b",
  "messages": [{"role": "user", "content": "..."}],
  "chat_template_kwargs": {"enable_thinking": false}
}

Usage

Works with llama.cpp, LM Studio, Jan, koboldcpp, and other GGUF-compatible runtimes.

llama-server:

llama-server -m Gemma4-26B-A4B-Uncensored-HauhauCS-Balanced-Q4_K_P.gguf \
  --mmproj mmproj-Gemma4-26B-A4B-Uncensored-HauhauCS-Balanced-f16.gguf \
  --jinja -c 32768 -ngl 99

llama-cli:

llama-cli -m Gemma4-26B-A4B-Uncensored-HauhauCS-Balanced-Q4_K_P.gguf \
  --mmproj mmproj-Gemma4-26B-A4B-Uncensored-HauhauCS-Balanced-f16.gguf \
  --jinja -c 32768 -ngl 99

Other Models

* Tested with both automated and manual refusal benchmarks — none have been found in standard use. A small number of edge-case prompts deflect on the first ask but comply on a re-ask or strategic framing. If you hit one that's actually obstructive to your use case, join the Discord and flag it so I can work on it in a future revision.
