Setup tutorial: Moondream 2 on RTX 4080
AI-generated, GPU-specific. Verified commands for your exact hardware.
Moondream 2 runs at Grade S on an NVIDIA GeForce RTX 4080 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 allows for a practical context window of up to 2048 tokens, ensuring smooth and efficient operation.

For optimal performance on the NVIDIA GeForce RTX 4080 with 16GB VRAM, use the --n-gpu-layers parameter to offload layers to the GPU. Setting --n-gpu-layers to 32 should utilize the GPU effectively while keeping VRAM usage under 1.5GB. Additionally, enable flash attention (--flash-attn) to further optimize performance. With 14.5GB of VRAM remaining, you can comfortably handle large context windows up to 2048 tokens.
Troubleshooting
Low token generation speed
Ensure that the --flash-attn flag is set and that the --n-gpu-layers parameter is optimized for your GPU. Try increasing --n-gpu-layers to 32.
Out of memory errors
Reduce the --n-gpu-layers value to 16 or lower to decrease VRAM usage. If the issue persists, try running the model on the CPU with --device cpu.
Model fails to load
Verify that the model file has been downloaded correctly and that the file path is correct. Re-run the 'ollama pull' command to ensure the model is fully downloaded.
Alternative runtimes
Alternative runtimes include LM Studio, llama.cpp, and Jan. LM Studio offers a more user-friendly interface and is suitable for users who prefer a graphical environment. llama.cpp is highly customizable and can be used for fine-tuning models, but it requires more manual configuration. Jan is lightweight and ideal for resource-constrained systems, but it may not offer the same level of performance as Ollama on the NVIDIA GeForce RTX 4080.
