Template

The template lets you dynamically format and combine variables from previous nodes into a single text-based output using Jinja2, a powerful templating syntax for Python. It's useful for combining data from multiple sources into a specific structure required by subsequent nodes. The simple example below shows how to assemble an article by piecing together various previous outputs:

Beyond naive use cases, you can create more complex templates as per Jinja's documentation for a variety of tasks. Here's one template that structures retrieved chunks and their relevant metadata from a knowledge retrieval node into a formatted markdown:

{% for item in chunks %}
### Chunk {{ loop.index }}. 
### Similarity: {{ item.metadata.score | default('N/A') }}

#### {{ item.title }}

##### Content
{{ item.content | replace('\n', '\n\n') }}

---
{% endfor %}

This template node can then be used within an Advanced Agent to return intermediate outputs to the end user, before a LLM response is initiated.

The Answer node in a Advanced Agent is non-terminal. It can be inserted anywhere to output responses at multiple points within the flow.
