โœจ Gemma4-12B-Reasoning-Distill (GGUF) โœจ

๐Ÿฃ Tiny footprint, big brain โ€” local AI for everyone

No matter your GPU. No matter your RAM. If you've got ~4.5 GB of VRAM or unified memory free, you can run your own private, offline AI right now. ๐Ÿš€ Tuned on Opus 4.6, 4.7 & 4.8 reasoning data, it delivers a major leap in reasoning power โ€” whether you're asking questions or writing code. ๐Ÿง ๐Ÿ’ป All local, all yours, no API, no cloud.

โšก NEW โ€” the MTP version is here! Free speed ๐ŸŽ‰

As of June 7, 2026, mainline llama.cpp just merged Gemma 4 MTP support โ€” so the MTP draft model is now live in the MTP/ folder. Drop it next to any quant and generation gets noticeably faster with identical output (speculative decoding is lossless) โ€” just add a couple of flags. ๐Ÿ‘‰ See โšก Speed it up with MTP below. ๐Ÿ’š


๐Ÿ“ฆ Pick your size (GGUF quants)

Quant Size Vibe
๐ŸŸข Q2_K 4.5 GB tiniest โ€” runs almost anywhere
๐Ÿ”ต Q4_K_M 6.87 GB the sweet spot ๐Ÿ‘Œ (recommended)
๐ŸŸฃ Q6_K 9.11 GB near-lossless
โšช Q8_0 11.8 GB basically full quality
(f16) 22.2 GB full precision (overkill for most)

๐Ÿงฎ "Will it fit?" โ€” context length cheat-sheet

Rough estimates ๐Ÿค“ (assumes q8_0 KV cache + ~1.5 GB overhead; use q4_0 KV cache for โ‰ˆ2ร— more context!). Max context is 131K. "โ€”" = won't fit, pick a smaller quant. โœ‚๏ธ

Your VRAM / unified mem ๐ŸŸข Q2_K (4.5G) ๐Ÿ”ต Q4_K_M (6.87G) ๐ŸŸฃ Q6_K (9.11G) โšช Q8_0 (11.8G)
8 GB ~16K ctx tight (~2โ€“4K) โ€” โ€”
12 GB ~48K ~30K ~12K โ€”
16 GB ~80K ~64K ~44K ~22K
24 GB 131K (max) ๐ŸŽ‰ ~128K ~110K ~88K
32 GB 131K 131K 131K 131K

๐Ÿ’ก Apple Silicon / integrated GPUs with unified memory count too โ€” same numbers, just slower than a dGPU. ๐Ÿ’ก Low on room? Drop a quant or switch KV cache to q4_0 and your context roughly doubles.


โšก Speed it up with MTP (free & lossless) ๐ŸŽ๏ธ

New as of June 7, 2026! Gemma 4's Multi-Token Prediction drafter lets the model guess a few tokens ahead and verify them in one shot โ€” so you get more tokens/sec with byte-for-byte identical output. Pure speed, zero quality cost. ๐Ÿช„

1. Grab the tiny draft from the MTP/ folder:

Draft file Size Use it for
โšช gemma-4-12B-it-MTP-Q8_0.gguf 0.44 GB recommended โ€” tiny + full speed
โ€ฆ-F16.gguf / โ€ฆ-BF16.gguf 0.82 GB full-precision draft (overkill)

๐Ÿ’ก The draft is tiny โ€” keep it Q8 or higher (over-quantizing a draft just lowers its hit rate). It pairs with any quant of the main model.

2. You need a fresh llama.cpp build โ€” June 7 2026 (b9553) or newer. MTP was just merged, so older builds can't load the draft (unknown architecture: 'gemma4-assistant').

3. Run it exactly like below, just +3 flags (--model-draft, --spec-type, --n-gpu-layers-draft):

@echo off
cd /d C:\llama.cpp
llama-server.exe ^
  -m C:\models\gemma4-opus48-Q4_K_M.gguf ^
  --model-draft C:\models\MTP\gemma-4-12B-it-MTP-Q8_0.gguf ^
  --spec-type draft-mtp --spec-draft-n-max 4 ^
  --ctx-size 16384 --n-gpu-layers 99 --n-gpu-layers-draft 99 ^
  --no-mmap -fa on ^
  --temp 1.0 --top-p 0.95 --top-k 64 ^
  --host 0.0.0.0 --port 18080
pause

Measured on a single RTX 5090 (Q4_K_M main + Q8 draft): ~1.3ร— faster at greedy and ~1.2ร— at the default thinking sampling โ€” free, with no change to output. ๐ŸŽˆ

๐Ÿ”ง Heads-up: this is the stock Gemma drafter (trained on base Gemma 4), so on this fine-tune the hit rate โ€” and thus the speedup โ€” is a little lower than on vanilla Gemma 4. A re-aligned draft could push it higher (maybe a future update). Either way: free speed, no downside. ๐Ÿ’š


๐Ÿš€ How to run it (super easy)

Option A โ€” llama.cpp (recommended) ๐Ÿฆ™

  1. Grab a quant above (e.g. โ€ฆ-Q4_K_M.gguf) and llama-server from llama.cpp.

    โš ๏ธ Needs a recent llama.cpp (this is the gemma4_unified architecture โ€” older builds won't load it).

  2. Run a server (Windows .bat shown โ€” tweak --port, --ctx-size to taste):
@echo off
cd /d C:\llama.cpp
llama-server.exe ^
  -m C:\models\gemma4-opus48-Q4_K_M.gguf ^
  --ctx-size 16384 ^
  --n-gpu-layers 99 ^
  --no-mmap ^
  -fa on ^
  --cache-type-k q8_0 --cache-type-v q8_0 ^
  --temp 1.0 --top-p 0.95 --top-k 64 ^
  --host 0.0.0.0 --port 18080
pause
  1. Open http://localhost:18080 and chat. ๐ŸŽ‰ (Tip: bump --ctx-size per the table; use q4_0 KV for more.)

Option B โ€” one-click apps ๐Ÿ–ฑ๏ธ

Works in LM Studio, Jan, Ollama, etc. โ€” just import the GGUF, pick your quant, go. ๐Ÿพ

๐Ÿง  Thinking mode

This model thinks in Gemma's native thought channel. Keep enable_thinking=true (the default chat template handles it). Recommended sampling: temp 1.0, top_p 0.95, top_k 64.


โš ๏ธ Good to know

  • Reduced refusals: the training data omits safety hedging, so this refuses less than the base model. It is not safety-aligned โ€” add your own guardrails for production. Use responsibly. ๐Ÿ™
  • Reasoning is stylistic synthetic CoT โ€” great for structure, but double-check facts/numbers.
  • English-centric.
