ChatGPT Plus vs Google AI Pro
ChatGPT Plus is our pick of the standard band. Both cost the same $20/mo.
Our verdict
The OpenAI ladder. Every paid ChatGPT rung runs the same Codex CLI and the same GPT 5.6 models; upgrading changes the weekly allowance and nothing else. Plus is already the lightest quota burn we measure, about 3% of its window per real-world run, so the upper rungs sell headroom most people never touch.
The Google ladder. It splits at $20. Below that, AI Plus is Gemini in the chat apps and no coding agent worth the name. From AI Pro up, every rung runs the same Antigravity CLI with the same models; Ultra buys volume, not capability.
ChatGPT Plus is our pick of the standard band.
ChatGPT Plus is for steady everyday use where headroom matters more than raw capability; Google AI Pro is for fast, capable work at $20, plus Gemini everywhere else.
Both cost the same $20/mo.
Our whole suite fits about 30 to 40 times a week on ChatGPT Plus and about 9 to 10 times a week on Google AI Pro. Each figure is a share of its own plan's allowance.
None of the GPT 5.6 models is the one we would pick on capability alone. What Plus has is the meter: one real-world run costs about 3% of the weekly window, the lightest burn we measure anywhere, so the limit is never what stops you. This is the plan where you stop thinking about quota.
Pros
- One run costs ~3% of the weekly window, the lightest burn we measure
- Three GPT 5.6 models to switch between
- The quickest medians in the field
Cons
- The models sit mid-field, not at the front
- Headroom is the whole pitch
Best for Steady everyday use where headroom matters more than raw capability.
How far it goes: about 30 to 40 times a week
Our whole Real-world issues suite runs about 30 to 40 times a week on this plan, depending on which model you run.
That works out at about 11c to 16c of the subscription per run, at the list price.
Measured on this plan, at 2.4% to 3.5%/1w of its allowance per run. A share belongs to the plan it was measured on, so we never subtract one plan's from another's.
The most improved plan we track, and fast-and-cheap now belongs to it outright. Gemini 3.7 Flash is quick and genuinely good on the work we give it, prompted apps included. The gripe is the Antigravity harness itself: rough-looking, and looser with your instructions than the better harnesses.
Pros
- 3.7 Flash owns the fast-and-cheap lane: quick and actually good
- A real coding agent at $20
- Gemini in Docs, Gmail and the chat app thrown in
Cons
- About eight real-world runs empty the weekly window
- The Antigravity harness looks rough and is loose with instructions
Best for Fast, capable work at $20, plus Gemini everywhere else.
How far it goes: about 9 to 10 times a week
Our whole Real-world issues suite runs about 9 to 10 times a week on this plan, depending on which model you run.
That works out at about 39c to 52c of the subscription per run, at the list price.
Measured on this plan, at 8.5% to 11.3%/1w of its allowance per run. A share belongs to the plan it was measured on, so we never subtract one plan's from another's.
