ChatGPT Go costs $8/mo; Google AI Plus costs $5/mo. More usage is expected from the more expensive plan; the question is whether it buys anything else.
Google AI Plus vs ChatGPT Go: choose ChatGPT Go if you're paying for the coding. ChatGPT Go costs $8/mo; Google AI Plus costs $5/mo. Prices are the providers' own list prices, and the verdict is ours rather than a score. The two plans are compared on what a week of real coding tasks fits, not on a feature list.Measured
Our verdict
Choose ChatGPT Go if you're paying for the coding. It gets you into Codex for little money, even though the limit will push regular users toward Plus.
Choose Google AI Plus if you want Gemini in Google apps and do not need a coding agent. Its value is the Google bundle, not the agent.
Go gets you onto Codex for $8. It runs the same Codex CLI as ChatGPT Plus, so nothing changes when you upgrade except the limit. The limit is what you will notice first. We would rather start at $20, but if $8 is the budget, this is the plan.
Pros
The cheapest way onto Codex
Same Codex CLI as Plus
Cons
Tight enough that you will soon want Plus
Not enough usage for real work
Best for A cheap first step onto Codex.
How far it goes: we have not measured this plan
