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

TL;DR

Moondream 2 runs at Grade S on the NVIDIA GeForce RTX 5080 with Q4_K_M quantization, achieving ~580 tok/sec.

Prerequisites

Before starting, ensure you have at least 2GB 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 recommended settings, Moondream 2 should achieve ~580 tok/sec, using approximately 1.5GB of VRAM. The remaining 14.5GB of VRAM provides ample headroom for handling larger context windows, enabling more complex and detailed interactions.

1. Install runtimeOllama

pip install ollama
ollama config set device 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 --context-length 2048 --n-gpu-layers 32 --flash-attn
ollama chat --model moondream2-20250414-Q4_K_M.gguf

4. Optimize for RTX 5080

For optimal performance on the NVIDIA GeForce RTX 5080 with 16GB VRAM, set --n-gpu-layers to 32 to utilize the GPU efficiently. Enable --flash-attn for faster attention computations. With 1.5GB VRAM used by the model, you have 14.5GB of VRAM available for context, allowing for a large practical context window.

Troubleshooting

Low token throughput (< 500 tok/sec)

Ensure that --flash-attn is enabled and --n-gpu-layers is set to 32. Update your NVIDIA drivers to the latest version.

Out of memory errors

Reduce the --context-length to 1024 or lower to decrease VRAM usage.

Model fails to load

Check that the model file is correctly downloaded and not corrupted. Verify the file integrity using md5sum or sha256sum.

Alternative runtimes

Alternative runtimes include LM Studio and llama.cpp. LM Studio offers a graphical interface and is suitable for users who prefer a visual setup. llama.cpp is a lightweight option for running models directly from the command line, ideal for scripting and automation. Jan is another runtime that supports advanced features like tensor parallelism, useful for multi-GPU setups.
