NobodyWho/Google_Gemma4-12B-GGUF

Overview

GGUF quantization of Google's Gemma 4 12B (Unified) model, re-hosted for NobodyWho. The unsloth build already ships a tool-calling setup and recommended sampling metadata (general.sampling: temp 1.0, top_k 64, top_p 0.95), so nothing needs patching — the model is verified with NobodyWho's test suite. The 12B Unified variant is the laptop-class Gemma 4 — stronger reasoning and multimodal capability than the edge (E2B/E4B) models while staying well below the larger MoE/dense variants in memory. Multimodal (text + image), multilingual, Apache 2.0.

Model Capabilities

Text generation — instruction-following chat, stronger reasoning
Tool calling — native function calling with grammar-constrained output
Vision — ⚠️ the 12B mmproj (vision + audio encoder) currently fails to load in NobodyWho (llama.cpp MTMD/CLIP init error); needs a newer llama.cpp. Text + tool calling are unaffected. For vision today, use Gemma 4 E2B/E4B (verified working)
Long context — 256k tokens
Multilingual — 140+ languages

Available Quantizations

File	Approach	Tool-calling tests
`gemma-4-12b-it-BF16.gguf`	Sampling embedded upstream	not separately run
`gemma-4-12b-it-Q8_0.gguf`	Sampling embedded upstream	14/14
`gemma-4-12b-it-Q4_K_M.gguf`	Sampling embedded upstream	14/14
`mmproj-BF16.gguf`	Vision projection — ⚠️ does not load in NobodyWho yet	—

Tool calling verified on Q8_0 and Q4_K_M (14/14 each, June 2026; BF16 hosted but not separately tested — 24 GB). Vision: the 12B mmproj fails to load in the current NobodyWho build (llama.cpp MTMD/CLIP init error) — Gemma 4 E2B/E4B vision is verified working. Quant names follow the unsloth gemma-4-12b-it-GGUF repo.

Quick Start

Using the NobodyWho library:

from nobodywho import Chat

chat = Chat("huggingface:NobodyWho/Google_Gemma4-12B-GGUF/gemma-4-12b-it-Q4_K_M.gguf")
response = chat.ask("What is the capital of Denmark?").completed()
print(response)  # The capital of Denmark is Copenhagen.

Vision

⚠️ Not working yet on 12B: the mmproj fails to load in the current NobodyWho build. The snippet below is the intended API (it works for Gemma 4 E2B/E4B today).

from nobodywho import Model, Chat, Prompt, Image, Text

model = Model(
    "huggingface:NobodyWho/Google_Gemma4-12B-GGUF/gemma-4-12b-it-Q4_K_M.gguf",
    projection_model_path="huggingface:NobodyWho/Google_Gemma4-12B-GGUF/mmproj-BF16.gguf",
)
chat = Chat(model=model, system_prompt="You are a helpful assistant.")
response = chat.ask(Prompt([
    Text("What is in this image?"),
    Image("./photo.png"),
])).completed()
print(response)
