Failed to get a valid response from Ollama (HTTP Status: 404)

If you see this error:

Failed to get a valid response from Ollama. (HTTP Status: 404 - Server message: {"error":"model \"gemma3:1b\" not found, try pulling it first"})

…it means that the model you're trying to use is not installed on your machine.

✅ Step 1: Check the Model in Settings

1. Open Excel and go to the XLlama tab.

2. Click Settings.

3. Under Model Name, use the dropdown to select one of the models already installed on your machine.

If the dropdown is empty or you don’t see the model you want — keep reading.

✅ Step 2: Install the Model

You can install more models by clicking the Install More Models link in the Settings window.

Or you can directly navigate to THIS page, which explains how to install a specific model on your machine.

After that, go back to Excel, open Settings, and you should now see your new model in the dropdown. Select it — and then try running XLlama again.
