Automate GPT-4o Fine-Tuning with Google Sheets or Airtable Data

Automates pulling ready examples from Google Sheets or Airtable, creating JSONL files, fine-tuning GPT-4o, and logging the model ID back to a registry. Saves hours of manual OpenAI fine-tuning setup.

This n8n workflow streamlines the entire GPT-4o fine-tuning process for users managing before/after text examples in spreadsheets. It triggers on a schedule (weekly by default), fetches rows marked 'Ready' from Google Sheets or Airtable, converts them into properly formatted chat JSONL files (splitting 80/20 for train/validation), uploads to OpenAI, initiates the fine-tune job, polls for completion, and appends the new model ID and metadata back to a registry sheet or table.
