What is Output Format?

Tela allows you to define a structured Output Format for your prompts.
Output Format is a way to communicate to your Canvas how you want to receive the response, providing guidelines that will help the model extract information with precision.
Structuring an Output Format is useful when:
  • You want your output to consistently be generated within the same framework
  • You need to integrate your Canvas with other processes, that require structured data
  • You want to organize the output from your Canvas in lists or tables

​
Setting up your Output Format

To add an Output Format to your Canvas you can click on the Output Format button on the bottom left of the Craft experience. Output Format This will open the Output Format interface, where you can click Add Attribute to create your first attribute. Each attribute has a name, a description and a type: Attribute type selector

​
Creating attributes

Attributes are the guidelines that will tell your Canvas what to respond and how to structure the content. Each attribute has a label, a description and a type.
  • Label: a relevant name for the attribute, similar to naming a variable when programming or a column header on a table. We recommend using only letters, numbers and underscores for your labels.
  • Description: a short text describing what is the desired output and how it should be formatted, if applicable. This can complement and reinforce the instructions for your Prompt.
  • Type - The type of attribute, which can be:
    • Text - textual or string content
    • Number - numeric content
    • Boolean - Either TRUE or FALSE
    • List - a list of Attributes of variable length
    • Object - a group of Attributes representing an object
    • Table - a table of Attributes of variable length
    • Categories (Enum) - one value from a fixed set of options you define (for example, active, expired or terminated)
Lists and objects are powerful types of attributes that can be used together in several applications. Since they are more complex, the next section will provide more details about how to use them.

​
Diving deeper into Lists

Lists are useful when you can have more than one valid response for an attribute. Using lists, you can tell the Canvas to bring you everything that can be a valid response for that attribute.
When using a list, you will notice that it requires a new Type, which will be the Type of the elements inside your list.

Example

Supposing you have a Canvas that reads contracts and you want every party that signs it.You can create an attribute parties with the type List of Object, where each object has a name and a role:Output Format with a parties list of objectsWith this list attribute, your Canvas will look for every party in the contract, and the response will contain one item per party.

​
Diving deeper into Objects

Objects are often described as a digital representation of something in the real world, they can have any number of attributes that will provide information related to it.
You will be asked to provide a type to the objects you create. It can be any one of Tela’s attribute types, even other Objects and Lists, allowing you to create complex structures if you need.

Example

In the example above, each item of parties is an Object with two Text attributes, name and role. You can nest Objects and Lists as deep as you need, for example an Object address inside each party.
