Difficulty: Intermediate
Software: Ollama
Hardware: For the publisher's 3.4 GB Ollama text package at a short 4K context, we estimate at least 8 GB GPU memory or 16 GB Apple unified memory. For a more comfortable starting point, use 16 GB GPU memory or 16 GB unified memory. These are capacity estimates, not speed tests; longer context and other apps need additional headroom.

THE WORKFLOW

Set up Qwen3.5 · 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.

Install Ollama

Ollama is the local runtime used here. Download and install the Ollama application for Windows, macOS, or Linux from the official Ollama website, then make sure the ollama command is available in your terminal or command prompt.

Download and start Qwen3.5 4B

Run the model directly. This downloads the 3.4 GB package the first time and then starts an interactive chat session in your terminal.

ollama run qwen3.5:4b

Send your first prompt

Once the prompt appears, type a plain user message and press Enter. Qwen3.5 operates in thinking mode by default, so you may see content inside a thinking block before the final answer. For example, ask: In two sentences, explain what a local language model is and why private chat can be useful.

Confirm the model responds

Read the text that appears after your prompt. A correct result is a coherent, non-empty answer produced by Qwen3.5 4B in your terminal, optionally preceded by thinking content. If you receive a generated answer, the local chat is working.

SUCCESS CHECK · Qwen3.5 · 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

The download or run fails because the model package is unavailable.

Install or update Ollama, then run the same documented command again: ollama run qwen3.5:4b

The model takes a long time to answer or the machine runs out of memory.

Close other memory-heavy applications and try again. If the machine is very constrained, use a smaller local model, because the documented Qwen3.5 4B package is 3.4 GB.

You see thinking content before the answer and think the model is stuck.

Wait for the final response after the thinking section. Qwen3.5 operates in thinking mode by default.
