The comparison nobody puts on the pricing page

Every one of these models is wrong about 5–15% of the time on hard questions, and they're wrong differently. Claude will confidently summarize a contract clause that isn't there; GPT-5 will invent a citation; Gemini will miss a nuance in a video you know is in there. Single-model users absorb those errors silently. Multi-model users catch them: the second opinion costs one click, not another subscription.

That's the actual argument for a sandbox over a choice. The question isn't 'which AI is best' — it's 'how much is it worth to know which answer is right today, for this task, without paying three companies monthly to find out?'

What 'choosing' looks like when you don't have to

So which should you buy?

  • One subscription, maximum quality: Claude Pro — the best default for professional knowledge work in 2026.
  • You need the Google ecosystem: Gemini Advanced — Workspace integration and video understanding.
  • You need the ecosystem everyone knows: ChatGPT Plus — plugins, voice, familiarity.
  • You do real work with AI: all of them, at once, for less than two of them cost separately. That's what Sandbox is for.

Stop choosing. Start comparing.
