We strongly recommend checking that your template
isn't printing extra spaces where it shouldn't be!
{% for message in messages %}
    {% if message['role'] == 'user' %}
        {{ ' ' }}
    {% endif %}
    {{ message['content'] }}
    {% if not loop.last %}
        {{ '  ' }}
    {% endif %}
{% endfor %}
{{ eos_token }}
If you've never seen one of these before, this is a Jinja template.
Jinja is a templating language that allows you to write simple code that generates text.
