Partner Nodes concurrency

Last updated: June 12, 2026

This article explains how Partner Nodes run in parallel.

Q. Can I run Partner Nodes in parallel?

Yes. Independent Partner Node branches within a single workflow can run in parallel automatically.

You do not need to enable this separately.

Actual concurrency may still depend on factors such as:

  • Available credits

  • Provider-side limits

  • Workflow structure

  • Your Partner Nodes concurrency limit

Q. Can I run multiple workflows at the same time?

This depends on your environment.

Comfy Cloud

  • Supports running multiple workflows in parallel depending on your subscription plan

  • Additional jobs may queue automatically

ComfyUI Local

  • Processes workflow runs through a single queue

  • Parallel execution may still happen inside an individual workflow

Q. What limits Partner Nodes concurrency?

Partner Nodes concurrency is controlled at the account level.

Requests beyond your concurrency limit may be rejected with a 429 error until existing requests complete.

Please note:

  • New accounts start with a default concurrency limit

  • Limits may increase automatically based on recent credit purchases

  • Self-serve limits scale automatically up to a supported maximum

  • Higher limits may require contacting support
