🚀 Quick Start

How to Use Gemma 3 Vision with llama.cpp

To utilize the experimental support for Gemma 3 Vision in llama.cpp, follow these steps:

1. Clone the latest llama.cpp Repository:

   git clone https://github.com/ggml-org/llama.cpp.git
   cd llama.cpp
   

2. Build the Llama.cpp: Build llama.cpp as usual: Building the project. Once llama.cpp is built, copy the ./llama.cpp/build/bin/llama-gemma3-cli to a chosen folder.

3. Download the Gemma 3 gguf file: Gemma 3 gguf files. Choose a gguf file without the mmproj in the name. Example gguf file: google_gemma-3-12b-it-q4_k_l.gguf. Copy this file to your chosen folder.

4. Download the Gemma 3 mmproj file Gemma 3 mmproj files. Choose a file with mmproj in the name. Example mmproj file: google_gemma-3-12b-it-mmproj-bf16.gguf. Copy this file to your chosen folder.

5. Copy images to the same folder as the gguf files or alter paths appropriately. In the example below, the gguf files, images, and llama-gemma-cli are in the same folder. Example image: car-1.jpg. Copy this file to your chosen folder.

6. Run the CLI Tool: From your chosen folder:

llama-gemma3-cli -m google_gemma-3-12b-it-q4_k_l.gguf --mmproj google_gemma-3-12b-it-mmproj-bf16.gguf

> what is the image of
Here's a breakdown of what's in the image:

**Subject:** The primary subject is a black Porsche Panamera Turbo driving on a highway.

**Details:**

*   **Car:** It's a sleek, modern Porsche Panamera Turbo, identifiable by its distinctive rear design, the "PORSCHE" lettering, and the "Panamera Turbo" badge. The license plate reads "CVC-911".
*   **Setting:** The car is on a multi-lane highway, with a blurred background of trees, a distant building, and a cloudy sky. The lighting suggests it's either dusk or dawn.
*   **Motion:** The image captures the car in motion, with a slight motion blur to convey speed.

**Overall Impression:** The image conveys a sense of speed, luxury, and power. It's a well-composed shot that highlights the car's design and performance.

Do you want me to describe any specific aspect of the image in more detail, or perhaps analyze its composition?

✨ Features

If you find these models useful

Please click like ❤️. Also, I’d really appreciate it if you could test my Network Monitor Assistant at 👉 Network Monitor Assitant. 💬 Click the chat icon (bottom right of the main and dashboard pages). Choose an LLM; toggle between the LLM Types TurboLLM -> FreeLLM -> TestLLM.

What I'm Testing

I'm experimenting with function calling against my network monitoring service. Using small open source models. I am into the question "How small can it go and still function". 🟡 TestLLM – Runs Phi-4-mini-instruct using phi-4-mini-q4_0.gguf, llama.cpp on 6 threads of a CPU VM (Should take about 15s to load. Inference speed is quite slow and it only processes one user prompt at a time—still working on scaling!). If you're curious, I'd be happy to share how it works!

The other Available AI Assistants

🟢 TurboLLM – Uses gpt-4o-mini Fast! Note: tokens are limited since OpenAI models are pricey, but you can Login or Download the Free Network Monitor agent to get more tokens. Alternatively, use the TestLLM. 🔵 HugLLM – Runs open-source Hugging Face models Fast, Runs small models (≈8B) hence lower quality, Get 2x more tokens (subject to Hugging Face API availability).

Choosing the Right Model Format

Selecting the correct model format depends on your hardware capabilities and memory constraints.

BF16 (Brain Float 16) – Use if BF16 acceleration is available

• A 16-bit floating-point format designed for faster computation while retaining good precision.
• Provides similar dynamic range as FP32 but with lower memory usage.
• Recommended if your hardware supports BF16 acceleration (check your device’s specs).
• Ideal for high-performance inference with reduced memory footprint compared to FP32.

📌 Use BF16 if: ✔ Your hardware has native BF16 support (e.g., newer GPUs, TPUs). ✔ You want higher precision while saving memory. ✔ You plan to requantize the model into another format.

📌 Avoid BF16 if: ❌ Your hardware does not support BF16 (it may fall back to FP32 and run slower). ❌ You need compatibility with older devices that lack BF16 optimization.

F16 (Float 16) – More widely supported than BF16

• A 16-bit floating-point high precision but with less of range of values than BF16.
• Works on most devices with FP16 acceleration support (including many GPUs and some CPUs).
• Slightly lower numerical precision than BF16 but generally sufficient for inference.

📌 Use F16 if: ✔ Your hardware supports FP16 but not BF16. ✔ You need a balance between speed, memory usage, and accuracy. ✔ You are running on a GPU or another device optimized for FP16 computations.

📌 Avoid F16 if: ❌ Your device lacks native FP16 support (it may run slower than expected). ❌ You have memory limitations.

Quantized Models (Q4_K, Q6_K, Q8, etc.) – For CPU & Low-VRAM Inference

Quantization reduces model size and memory usage while maintaining as much accuracy as possible.

• Lower-bit models (Q4_K) → Best for minimal memory usage, may have lower precision.
• Higher-bit models (Q6_K, Q8_0) → Better accuracy, requires more memory.

📌 Use Quantized Models if: ✔ You are running inference on a CPU and need an optimized model. ✔ Your device has low VRAM and cannot load full-precision models. ✔ You want to reduce memory footprint while keeping reasonable accuracy.

📌 Avoid Quantized Models if: ❌ You need maximum accuracy (full-precision models are better for this). ❌ Your hardware has enough VRAM for higher-precision formats (BF16/F16).

Model Information

Summary description and brief definition of inputs and outputs.

Description

Gemma is a family of lightweight, state-of-the-art open models from Google, built from the same research and technology used to create the Gemini models. Gemma 3 models are multimodal, handling text and image input and generating text output, with open weights for both pre-trained variants and instruction-tuned variants. Gemma 3 has a large, 128K context window, multilingual support in over 140 languages, and is available in more sizes than previous versions. Gemma 3 models are well-suited for a variety of text generation and image understanding tasks, including question answering, summarization, and reasoning. Their relatively small size makes it possible to deploy them in environments with limited resources such as laptops, desktops or your own cloud infrastructure, democratizing access to state of the art AI models and helping foster innovation for everyone.
