Automate GPT-4o fine-tuning with Google Sheets or Airtable data
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 AI workflow has 14 nodes and runs on a schedule (every day). Along the way it connects OpenAI, Airtable and Google Sheets.
How it runs
Trigger: On a schedule (every day).
- Get Examples from Sheet (Google Sheets): uses Google Sheets
- Get Examples from Airtable (Airtable): uses Airtable
- Create JSONL File (Code): runs custom JavaScript code
- Upload JSONL File (OpenAI): uses OpenAI
- Set GPT Model (Edit Fields (Set)): sets or maps fields
- Begin Fine-tune Job (HTTP Request): calls an HTTP API
- Wait: pauses before continuing
- Check Fine-Tune Job (HTTP Request): calls an HTTP API
- If: checks a condition and branches into true / false
- Add Fine-Tuned Model to Airtable (Airtable): uses Airtable
…plus 3 more steps. See the full node list below.
Services it uses
Before you upgrade to n8n 3.0
