Unless you’re on a Business plan, OpenAI and Gemini train on your data. More on that here.

That’s 71 dollars per person on starter plans, and it climbs the moment you exhaust the quotas. Expensive, and hard to control securely at scale.

One subscription, all three, or something else entirely is a real decision.

Short answer: yes. On the Free, Go, Plus, and Pro plans, your data is used for training. On Business and Enterprise, it isn’t.

Worth knowing before you hand ChatGPT subscriptions to your team.

The leaders in December 2025:

  • Text: Gemini 3 Pro
  • Coding: Claude Opus 4.5
  • Text-to-image: GPT Image 1.5

I asked Claude and Gemini for a title for this post. Gemini was thorough: three options across three angles, with a recommendation. Claude gave me half as many and no reasoning.

Claude’s suggestion was “Are You Using the Wrong AI?”. Gemini’s is the title that kept you reading.
