Group LLM data processing (DLC) components in Machine Learning Designer to run them as a single batch job — no intermediate data is written to storage between components, which reduces I/O overhead and speeds up your pipeline.
How it works
A group acts as a single execution unit that wraps multiple LLM-DLC components. When the group runs, all enclosed components execute in sequence without persisting intermediate results to storage. The group provides a unified set of configurations and produces a collective output consumed by downstream components.
Limitations
Currently, LLM-Risk Content Filtering (DLC) and LLM-Quality Predict (DLC) under the Large Model Data Preprocessing folder do not support grouping.
Some components do not support multi-node distributed operation. If a group contains such components, multi-node tasks fail. To check whether a component supports multi-node distributed operation, open the component's Tuning tab. If the Nodes parameter can be set to a value greater than 1, the component supports multi-node distributed operation.
Configuration hierarchy
Group-level configurations take precedence over individual component configurations. Within a group, settings are split across two levels:
| Level | What to configure |
|---|---|
| Group level | Text fields, image fields, video fields, computing resources, data output paths |
| Component level | Tuning parameters specific to each component |
Component-level tuning parameters are not overridden by the group. Configure them individually on each component.
Group output behavior
Grouped components do not produce individual outputs. The group emits a single collective output that combines the results of all enclosed components. In the example below, the connection originates from the center of the group, indicating that the output includes results from both LLM-Text Normalizer (DLC) and LLM-Clean Special Content (DLC)-1.
Create a group
Intelligent aggregation
Machine Learning Designer automatically detects canvas nodes that can be grouped. Click 
to aggregate them into a group, then click 
to configure resources for the group.
Manual aggregation
Click 
or use Shift+left-click to select multiple components. Right-click in an empty area and choose Group Selected Nodes. Then click to configure resources for the group.
