JetBrains Junie Local: An agent you own, not one you rent

The GitHub page for the Junie [1] script explicitly says "MacOS/Linux": It's the same curl command for the CLI

    curl -fsSL https://junie.jetbrains.com/install.sh | bash

To automatically install the local model after the CLI is installed, you run with th --local-model flag:

    curl -fsSL https://junie.jetbrains.com/install.sh | bash -s -- --local-model

There is a note in the bash script [2] that the local model needs MacOS for some reason:

    install_local_model() {
    echo ""
    log "Junie is installed. Setting up the local model..."
    if ! curl -fsSL "$LOCAL_MODEL_URL" | bash; then
        # The local model is an optional extra on top of a finished Junie install,
        # and it is the part most likely to be refused -- it needs macOS 26 on an
        # Apple M5 or newer with 40 GB of RAM. Whatever went wrong here, Junie itself
        # is installed, so say so plainly instead of leaving the run looking failed.
        echo ""
        log_error "The local model setup did not complete."
        log "Junie itself is installed and ready to use -- run: junie"
        log "To try the local model again: curl -fsSL $LOCAL_MODEL_URL | bash"
        exit 1
    fi
    }

But the GitHub repo README for "local" [3] does have instructions for Linux though, and makes it seem like the --local flag will work. As a hardy Linux hacker, you should probably just try it and see what happens.

Edit: Interestingly, I got Junie CLI on my M4 Mac but did NOT get the local model installed, which t looks like iwas going to me Qwen3.6-27B-MLX-4bit. (Needs a M5 GPU apparently.)

I did start Junie and it prompted me to connect to a local model, successfully detected Ollama and connected to that.
