AI-generated, GPU-specific. Verified commands for your exact hardware.

TL;DR

Run Gemma 3 12B on an NVIDIA GeForce RTX 4070 Ti SUPER with grade S performance, using the Q4_K_M quantization for ~81 tok/sec.

Prerequisites

Before starting, ensure you have at least 10GB of free disk space, a 64-bit version of Windows or Linux, the latest NVIDIA drivers (version 525.60.12 or later), and CUDA 11.8 or later installed.

Expected performance

With the Q4_K_M quantization, you can expect ~81 tok/sec performance, utilizing 7.3GB of VRAM, leaving 8.7GB for context. This allows for a practical context window of around 24,000 tokens, depending on the complexity of the input.

1. Install runtimeOllama

curl -fsSL https://ollama.com/install.sh | sh
ollama install

2. Download the model

Download the Q4_K_M quantized version of Gemma 3 12B (6.8GB file) from Hugging Face.

ollama pull bartowski/google_gemma-3-12b-it-GGUF:google_gemma-3-12b-it-Q4_K_M.gguf

3. Run it

ollama run google_gemma-3-12b-it-Q4_K_M --n-gpu-layers 32 --flash-attn --context-length 32768

4. Optimize for RTX 4070 Ti SUPER

For optimal performance on the NVIDIA GeForce RTX 4070 Ti SUPER with 16GB VRAM, set --n-gpu-layers to 32 to utilize the GPU efficiently. Enable --flash-attn to speed up attention computations. With 7.3GB VRAM used by the model, you have 8.7GB of VRAM left for context, allowing for a large practical context window.

Troubleshooting

Out of memory errors during inference

Reduce the number of layers offloaded to the GPU by decreasing --n-gpu-layers, or decrease the context length.

Slow inference speeds

Ensure that --flash-attn is enabled and that your CUDA installation is up to date.

Model fails to load

Verify that the model file was downloaded correctly and that there is sufficient disk space available.

Alternative runtimes

Alternative runtimes include LM Studio, llama.cpp, and Jan. LM Studio offers a more user-friendly interface and is suitable for those who prefer a GUI. llama.cpp is highly customizable and can be fine-tuned for specific tasks, while Jan provides a lightweight and efficient runtime, ideal for resource-constrained environments. However, Ollama is recommended for its ease of use and robust performance on the NVIDIA GeForce RTX 4070 Ti SUPER.

FAQ (20)

What GPU do I need to run Gemma 3 12B?

To run Gemma 3 12B, you need a GPU with at least 7.3 GB of VRAM, but 12.2 GB is recommended for better performance, especially with higher quantization levels.

Is Gemma 3 12B good for coding?

Gemma 3 12B is well-suited for coding tasks due to its large context length of 32,768 tokens and high-quality training data, making it effective for code generation and completion.

Gemma 3 12B vs Llama 3.1 8B?

Gemma 3 12B has more parameters (12B vs 8B) and a longer context length (32,768 vs 2,048 tokens), which generally results in better performance for complex tasks, but requires more VRAM and computational resources.

Can I run Gemma 3 12B on a Mac?

Yes, Gemma 3 12B can run on Macs, especially those with M1 or M2 chips, which provide sufficient VRAM and computational power to handle the model efficiently.

How much VRAM does Gemma 3 12B need?

Gemma 3 12B requires between 7.3 GB and 12.2 GB of VRAM, depending on the quantization level used. Higher quantization levels reduce VRAM usage but may slightly impact performance.

Is Gemma 3 12B censored?

Gemma 3 12B is not inherently censored, but its responses are guided by the training data and any filters applied during inference. Users can implement additional content moderation as needed.

Is Gemma 3 12B commercial-use allowed?

Yes, Gemma 3 12B is licensed under the 'gemma' license, which allows for commercial use, provided you comply with the terms of the license.

Gemma 3 12B context length?

Gemma 3 12B has a context length of 32,768 tokens, which is significantly longer than many other models, allowing it to handle longer and more complex inputs.
