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?'
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.
