THE WORKFLOW

Set up Spark X2.5 4B on your machine

Pick your operating system. Every command below is for the selected package and runtime.

Install Ollama for this operating system before running the model command.

01

Install the Ollama runtime

Download and install Ollama for your platform from the official download page: https://ollama.com/download. Native spark2_5 support requires Ollama v0.34.1 or later, so install a build at or above that version. On macOS and Windows the installer places the ollama binary on your PATH; on Linux follow the installer instructions on that download page. After installing, open a fresh terminal so the ollama command is available.

02

Download the Spark X2.5 4B model

Pull the Spark X2.5 4B model into your local Ollama library. This downloads the weights and registers the model under the identifier SparkLLM/Spark-X2.5-4B.

ollama run SparkLLM/Spark-X2.5-4B
03

Start a chat session and send your first prompt

The previous command opens an interactive prompt in your terminal once the model has loaded. Type a short question such as: What is the capital of Anhui Province? and press Enter. The model runs entirely on your machine; no data leaves your computer.

04

Confirm that the model responded

Read the terminal output. A successful setup shows a generated text answer below your prompt. For the example question, the expected answer is Hefei. If a coherent answer appears in the terminal, the model is running and responding locally. Type /bye and press Enter to exit the chat session when you are done.

03
SUCCESS CHECK · Spark X2.5 4B

Check the first local reply

Ask a short question with a known answer. Confirm the selected local model responds and verify the answer yourself before using it for private work.

This is a source-linked setup, not a YouRunAI hardware test. Confirm your exact runtime version, package, and output before relying on it.

Back to setup steps

When it doesn’t go to plan

Ollama reports an unknown model architecture or refuses to load Spark-X2.5-4B.

Your Ollama build is older than v0.34.1, which is the first version with native spark2_5 support. Install a current Ollama release from https://ollama.com/download and retry ollama run SparkLLM/Spark-X2.5-4B.

The model load fails or the machine runs out of memory.

A 4B parameter model needs substantial available memory. Close other memory-heavy applications and ensure you are running the model on hardware with enough RAM or VRAM for the weights and context you use.
