Building TableauTim GPT v1 : Part 1

I built a TableauTim GPT in a week, but honestly most of its magic is just GPT-4 wearing my brand — so I'm not launching it yet.

  • Custom GPTs don't retrain the underlying model on your uploaded knowledge — they search that knowledge at query time as added context, so feeding huge multi-hour transcripts is inefficient.
  • Smaller, precise GPTs (e.g. a Tableau LOD helper or a conference-recap bot) are far more useful than one giant catch-all model built from raw transcripts.
  • The 'actions' section is where the real power sits, letting a GPT integrate with APIs like Zapier or Todoist via the OpenAI schema, with authentication and a required privacy policy.
  • Much of a branded GPT's apparent quality comes straight from GPT-4 scraping the wider web, making it hard to know how much output reflects your own content versus OpenAI's training data.
  • Summarising transcripts into key bullet points before loading them as knowledge works better than dumping full-length transcripts.
