The best models, per seat:

• ChatGPT Business: 30 dollars
• Claude Pro: 20 dollars
• Gemini Enterprise: 21 dollars

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.
