๐ฃ 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. ๐
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. ๐ง ๐ป All local, all yours, no API, no cloud.
โก NEW โ the MTP version is here! Free speed ๐
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. ๐ See โก Speed it up with MTP below. ๐
๐ฆ Pick your size (GGUF quants)
๐งฎ "Will it fit?" โ context length cheat-sheet
Rough estimates ๐ค (assumes q8_0 KV cache + ~1.5 GB overhead; use q4_0 KV cache for โ2ร more context!).
Max context is 131K. "โ" = won't fit, pick a smaller quant. โ๏ธ
๐ก Apple Silicon / integrated GPUs with unified memory count too โ same numbers, just slower than a dGPU.
๐ก Low on room? Drop a quant or switch KV cache to q4_0 and your context roughly doubles.
โก Speed it up with MTP (free & lossless) ๐๏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. ๐ช
1. Grab the tiny draft from the MTP/ folder:
๐ก 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):
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. ๐
๐ง 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. ๐
๐ How to run it (super easy)
Option A โ llama.cpp (recommended) ๐ฆ
- Grab a quant above (e.g.
โฆ-Q4_K_M.gguf) and llama-server from llama.cpp.
โ ๏ธ Needs a recent llama.cpp (this is the gemma4_unified architecture โ older builds won't load it).
- Run a server (Windows
.bat shown โ tweak --port, --ctx-size to taste):
- Open
http://localhost:18080 and chat. ๐ (Tip: bump --ctx-size per the table; use q4_0 KV for more.)
Option B โ one-click apps ๐ฑ๏ธ
Works in LM Studio, Jan, Ollama, etc. โ just import the GGUF, pick your quant, go. ๐พ
๐ง 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.
โ ๏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. ๐
- Reasoning is stylistic synthetic CoT โ great for structure, but double-check facts/numbers.
- English-centric.
