🦙 Ollama Instructions

To quickly run this model using Ollama, you can use the following command:

ollama run hf.co/ZeroXClem/Qwen3-4B-NexusPrime-Q4_K_M-GGUF

This command downloads the pre-quantized GGUF version of the model and runs it locally, making it easy to experiment without extensive configuration.

For Optimal Inference Use the following ollama modelfile, create it as a file caled Modelfile.
