EndLoop - ComfyUI Built-in Node Documentation - ComfyUI

End Loop marks the end of a loop block. It collects the value produced by the last node in the loop body and returns either only the final iteration or every iteration, depending on the accumulate setting, while also passing a value back to Start Loop so the next iteration can begin.

Inputs

Parameter	Description	Data Type	Required	Range
`output_value`	Value returned by End Loop. It returns the final iteration or all iterations according to accumulate.	ANY	No	Any value type
`next_iteration_value`	Value sent from End Loop back to Start Loop for the next iteration.	ANY	No	Any value type
`accumulate`	Return output_value from every iteration when enabled; otherwise return only the final iteration.	BOOLEAN	No	`true` `false` (default: `false`)
`terminations`	Connect outputs that must execute on every iteration. Their values are not returned. Growable slots named `termination_1`, `termination_2`, and so on.	ANY	No	0 to 50 slots

Note: terminations is a growable list of slots with a minimum of 0 and a maximum of 50 connections. Values connected here force execution on every iteration but are not part of the returned result. Note: This node is an input list node, so its inputs receive the collected values from every loop iteration.

Outputs

Output Name	Description	Data Type
`outputs`	The final iteration’s output_value, or values accumulated across iterations when accumulate is enabled.	ANY (list)
