Setup tutorial: Moondream 2 on RTX 3080 Ti

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

TL;DR

Moondream 2 runs at Grade S on an NVIDIA GeForce RTX 3080 Ti with Q4_K_M quantization, achieving ~435 tok/sec.

Prerequisites

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

Expected performance

With the recommended settings, you can expect Moondream 2 to run at ~435 tok/sec, utilizing approximately 1.5GB of VRAM. Given the 12GB VRAM of the RTX 3080 Ti, you will have 10.5GB of VRAM headroom, allowing for a practical context window of up to 2048 tokens without running out of memory.

1. Install runtimeOllama

pip install ollama
ollama init

2. Download the model

Download the Q4_K_M quantized version of Moondream 2, which is a 1.0GB file.

ollama pull ggml-org/moondream2-20250414-GGUF:moondream2-20250414-Q4_K_M.gguf

3. Run it

ollama run moondream2-20250414-Q4_K_M.gguf
ollama chat --model moondream2-20250414-Q4_K_M.gguf

4. Optimize for RTX 3080 Ti

For optimal performance on the NVIDIA GeForce RTX 3080 Ti with 12GB VRAM, set --n-gpu-layers to 32 to utilize the GPU effectively. Enable flash-attn for faster inference and consider using tensor parallelism if running multiple instances. This configuration will allow you to achieve the target ~435 tok/sec while keeping VRAM usage around 1.5GB, leaving ample headroom for larger context windows.

Troubleshooting

Out of memory error during inference

Reduce --n-gpu-layers to 16 or enable CPU offloading with --cpu-offload.

Slow inference speed

Ensure flash-attn is enabled and update your CUDA drivers to the latest version.

Model fails to load

Verify the integrity of the downloaded model file and try re-downloading it.

Alternative runtimes

If you prefer a different runtime, consider LM Studio for a more user-friendly interface, llama.cpp for advanced customization options, or Jan for lightweight deployment. Each has its own strengths, but Ollama provides a balanced approach with ease of use and performance on the RTX 3080 Ti.
