Six plans, and only two of the jumps are about capability
Almost nobody arrives at a ChatGPT review to decide whether to try it. The decision is which plan to pay for, and the ladder now has six rungs: free, Go at $8 per month, Plus at twenty dollars, two Pro tiers at one hundred and two hundred, then Business seats.
Only two of those steps buy new capability. Free to Go buys volume, nothing else. Go to Plus is the real upgrade, because it is where the Sol reasoning models, projects, scheduled tasks and custom GPTs begin. Plus to Pro buys allowance, not features. Pro to Business buys administration.
So the question for most readers is narrow. If you use ChatGPT for everyday text and the occasional image, Go covers it for eight dollars. If you use it to think through work, Plus is the plan, and the twelve dollar difference is the whole reasoning stack.
The Pro tier nobody mentions
Every other review of this product describes Pro as a two hundred dollar plan. There are two Pro tiers. The cheaper one is one hundred dollars a month and unlocks five times the usage of Plus. The two hundred dollar tier unlocks twenty times. Same models, same reasoning levels, different ceilings.
That matters because the usual moment of decision is hitting a wall on Plus during a heavy week. The choice at that point is not a tenfold increase in spend. It is a five times allowance for double the Plus price, which is a much easier thing to justify and much easier to reverse.
The limits are real and OpenAI does not publish them
Here is the thing to plan around. Message allowances for file uploads, image creation, voice and deep research are described in the help centre as varying by plan, and no plan states a number. The free tier says unlimited everyday text chats subject to abuse prevention. Everything else is "expanded", "more" or "maximum".
You cannot forecast capacity from the published limits
We compared the vendor documentation and the pricing page rather than running metered usage tests. The gaps below are gaps in what OpenAI publishes, not gaps in our testing: outside the Business plan, where standard seats are documented at ten to one hundred Sol messages per five hour window, no tier states a numeric allowance.
That is a specific, checkable criticism, and it is the main reason this page does not score higher on trust. It also explains why the score sits where it does under how we rate: the capability is close to the top of the scale, and the reservations are commercial rather than technical.
Who owns what you type
On consumer plans, conversations are used to train the model by default. You turn that off under Settings, Data Controls, in the setting called "Improve the model for everyone", and your history stays intact. Temporary chats are deleted from OpenAI systems after thirty days and are never used for training.
Business and Enterprise are the other way round: business data is excluded from training by default, with SAML single sign on, an admin console and SOC 2 Type 2 behind it.
The practical reading is simple. A default that has to be switched off is a default most people never switch off, so if the work is confidential, the plan matters more than the setting.
Where a team stops paying per person
Two Plus subscriptions cost forty dollars a month and give you no admin console, no shared workspace and training on by default. Two Business seats cost fifty dollars monthly, or forty on annual billing, and give you all three. Above two people the seat plan wins on control before it wins on price, and the cap is two hundred users before the conversation becomes Enterprise.
Where a specialist still beats it
ChatGPT drafts well and holds nothing. That is the limitation that sends teams to a specialist. A brand voice profile that applies across a campaign, which is what Jasper is built around, keeps the twentieth post in a series sounding like the first, and no amount of custom instructions reliably reproduces that. For teams writing marketing copy at volume, Copy.ai does the same job per seat for less money.
If publishing is the actual use case, start from the best AI writing tools for blog posts rather than from here, and read how these tools actually work before paying for any of them. Everything else we score in this category sits under AI tools.
Who should stay free
If your use is everyday text, the free tier is not a trial. It is unlimited text chat on the Luna model, and the ceiling you eventually hit is uploads, images and deep research rather than conversation. Pay when you hit that ceiling, not before, and pay for Plus rather than Go unless the thing you ran out of was volume.
One caveat on Go specifically: OpenAI has said it will test ads in the United States on the free and Go tiers, and that Plus, Pro, Business and Enterprise stay ad free. Eight dollars a month for a plan that may show you ads is a strange middle, and it is the one plan here we would think twice about.
