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

TL;DR

Llama 3.2 1B Instruct runs at Grade S on an NVIDIA GeForce RTX 4070 Ti with FP16 quantization, achieving ~247 tok/sec.

Prerequisites

Before starting, ensure you have at least 2.3GB of free disk space, a compatible operating system (Windows or Linux), and the latest NVIDIA drivers (version 525.60.13 or later) with CUDA 11.8 installed.

Expected performance

With the FP16 quantization, you can expect the model to run at approximately 247 tokens per second, using around 2.8GB of VRAM. This leaves 9.2GB of VRAM available for context, enabling a practical context window of up to 131072 tokens.

1. Install runtimeOllama

pip install ollama
ollama init

2. Download the model

Download the FP16 quantized model (2.3GB file) from Hugging Face.

ollama pull bartowski/Llama-3.2-1B-Instruct-GGUF:Llama-3.2-1B-Instruct-f16.gguf

3. Run it

ollama run Llama-3.2-1B-Instruct-f16.gguf
ollama chat --model Llama-3.2-1B-Instruct-f16.gguf

4. Optimize for RTX 4070 Ti

For optimal performance on the NVIDIA GeForce RTX 4070 Ti with 12GB VRAM, set --n-gpu-layers to 12 to fully utilize the GPU. Enable flash attention (--flash-attn) to reduce memory usage and improve speed. With 2.8GB VRAM used by the model, you have 9.2GB of VRAM available for context, allowing for a practical context window of up to 131072 tokens.

Troubleshooting

Out of memory error during inference

Reduce the number of GPU layers (--n-gpu-layers) or enable flash attention (--flash-attn) to optimize memory usage.

Slow inference speed

Ensure that the latest NVIDIA drivers and CUDA are installed. Also, try increasing the batch size if your application allows it.

Model not found

Verify that the model was successfully downloaded and is located in the correct directory. Use the 'ollama list' command to check available models.

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 graphical environment. llama.cpp is highly optimized for low-memory devices and is ideal for running on smaller GPUs or embedded systems. Jan is another lightweight runtime that can be used for quick prototyping and testing.
