Compare

Description

The Compare node performs a logical/mathematical comparison between two input values and outputs the result as a boolean (True or False). It is part of the EasyUse/Logic/Math category and is useful for adding conditional logic to a workflow.

Inputs

a

• Type: ANYTYPE
• Optional: Yes

The first value to compare. Because this input accepts any type, a can be a number, string, tensor, or other ComfyUI data type.

b

• Type: ANYTYPE
• Optional: Yes

The second value to compare. As with a, any type can be supplied.

comparison

• Type: COMBO
• Optional: Yes
• Default: "a == b"

The comparison operator to apply. Choose the desired operator from the dropdown menu. The default is equality: a == b.

Outputs

BOOLEAN

• Type: BOOLEAN

The result of the comparison. The node outputs True when the comparison holds and False otherwise.

Usage Notes

• All inputs are marked optional, so the node can be placed in the graph and connected as needed. Leaving an input unconnected may result in it receiving None; make sure both values are supplied for meaningful comparisons.
• Since a and b accept any type, the available comparisons will be evaluated according to ComfyUI's data semantics. For scalar numbers and strings, the ordering comparisons usually behave as expected.
• The node is designed for logic and math use cases, such as comparing numeric parameters, checking conditions, and controlling downstream nodes with the resulting boolean.
