Input Nodes

The outputs from one model can be used as the inputs in another model. This allows you to link together the models in a graph. Linking models helps you build sophisticated AI solutions, that can zero-in on a specific use case.

Supported input and output types

To view your available models, just open your app and click Model Mode icon on the left hand side of the screen. From here just click the Create a Custom Model button in the top righthand corner of the screen.

Different models accept different types of inputs and return different types of outputs. They are named after the fields in the Data object of our API. This object is uses in inputs, annotations, models and workflows. Some examples include:

Inputs

• Concepts

• Embeddings

• Image

• Image or video

• Regions

Outputs

• Concepts

• Clusters

• Regions

The building blocks

You can create workflows out of any Clarifai Models or custom models that you have created for your app. The inputs and outputs supported by your custom models will depend on the inputs and outputs supported by the Clarifai Models, or model templates that you have used to build them.

Sample workflow with multiple connected nodes

The The following is an example of how to build a workflow with multiple connected nodes. Note that model IDs and model version IDs from the public clarifai/main application are fixed, so they are already hard-coded in the code examples below. It is possible to use other public model or model version IDs.

Suppressing the output from nodes

It is possible to turn the outputs from given nodes in your workflow on and off with the suppress_output endpoint. This can be helpful when you want to hide outputs for expensive return values like image crops or embedding. By default, this endpoint will be set to false, meaning that we do not suppress any model's output.
