LLM usage tracker & cost monitor with node-level analytics (v2)
Ready for 3.0Ready for 3.0. This template uses no nodes that n8n 3.0 removes. No removed nodes, versions or helpers found. Static check, last run 2026-10-19.
What this workflow does
This workflow has 12 nodes and runs manually, when you click “Execute workflow” (plus 1 other trigger). It uses only n8n's built-in nodes.
How it runs
Trigger: Manually, when you click “Execute workflow” (plus 1 other trigger).
- Get an execution (n8n): get (execution)
- Find Nodes with LLM Use (Code): runs custom JavaScript code
- Merge: merges the data from its input branches
- create models_used list (Code): runs custom JavaScript code
- Calculate cost (Code): runs custom JavaScript code
- Standardize names (Edit Fields (Set)): sets or maps fields
- model prices (Edit Fields (Set)): sets or maps fields
- Check correctly defined (Code): runs custom JavaScript code
- If: checks a condition and branches into true / false
- Stop and Error: stops the run with an error
Before you upgrade to n8n 3.0
Nothing in this workflow is removed in n8n 3.0, so it should import and run after the upgrade.
