Setup tutorial: Moondream 2 on RTX 3090 Ti

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

TL;DR

Moondream 2 runs at Grade S on an NVIDIA GeForce RTX 3090 Ti with Q4_K_M quantization, achieving ~870 tok/sec.

Prerequisites

Before starting, ensure you have at least 2GB of free disk space, a 64-bit version of Windows or Linux, and the latest NVIDIA drivers (version 525.60 or later) with CUDA 11.8 installed.

Expected performance

With the recommended settings, Moondream 2 should achieve ~870 tok/sec on the NVIDIA GeForce RTX 3090 Ti, using approximately 1.5GB of VRAM. This leaves 22.5GB of VRAM available for context, allowing for a practical context window of up to 2048 tokens.

1. Install runtimeOllama

pip install ollama
ollama config set runtime cuda

2. Download the model

Download the Q4_K_M quantized version of Moondream 2 (1.0GB file) from Hugging Face.

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 3090 Ti

For optimal performance on the NVIDIA GeForce RTX 3090 Ti with 24GB VRAM, use the --n-gpu-layers parameter to offload layers to the GPU. Set --n-gpu-layers to 32 to utilize the ample VRAM. Additionally, enable flash attention (--flash-attn) to further speed up inference. With 22.5GB of VRAM remaining after loading the model, you can comfortably handle large context windows.

Troubleshooting

Inference is slow or hangs

Ensure that the CUDA runtime is correctly configured with 'ollama config set runtime cuda'. If the issue persists, try reducing the number of GPU layers with '--n-gpu-layers 16'.

Out of memory errors

Reduce the number of GPU layers with '--n-gpu-layers 16' or disable flash attention with '--no-flash-attn'.

Model fails to load

Verify that the model file is downloaded correctly and not corrupted. Try downloading the model again with 'ollama pull ggml-org/moondream2-20250414-GGUF:moondream2-20250414-Q4_K_M.gguf'.

Alternative runtimes

Alternative runtimes include LM Studio, llama.cpp, and Jan. LM Studio is suitable for users who prefer a graphical interface, while llama.cpp offers more control over low-level optimizations. Jan is a lightweight option for quick prototyping. For the NVIDIA GeForce RTX 3090 Ti, Ollama is recommended due to its ease of use and optimized CUDA backend.
