ChatGPT’s pricing page lists Go at $8 a month and Plus at $20. Neither has an annual plan. OpenAI’s help centre says it doesn’t offer annual billing for Go, Plus or Pro, so the yearly cost is simply twelve times the monthly price: $96 a year for Go, $240 for Plus.
That’s $144 a year between them. The question that decides it: do you need the newest reasoning models, or do you mostly chat? If you mostly chat, Go covers you, and possibly Free does too.
What each plan costs over a year
| Plan | Monthly | Yearly | Ads |
|---|---|---|---|
| Free | $0 | $0 | May appear |
| Go | $8 | $96 | May appear |
| Plus | $20 | $240 | None |
| Pro | from $100 | from $1,200 | None |
Pro comes in three monthly tiers according to OpenAI’s help centre: Pro 100 at $100, Pro 200 at $200 and Pro 500 at $500. That’s $1,200 to $6,000 a year. It’s a separate conversation, and our AI subscription comparison covers it next to Claude and Google’s top tiers. This page is about the bottom two paid plans.
Plus costs 2.5 times what Go does.
What Go and Plus share
OpenAI’s plan comparison table shows more overlap than the prices suggest. On 14 October 2026 it listed these as the same on both plans:
- Context window. 54K for everyday chats and 256K for reasoning chats on both, which OpenAI translates as roughly 40 and 320 pages of text. Free gets 27K. So “longer conversations” is a reason to leave Free. It isn’t a reason to pick Plus over Go.
- Projects, scheduled tasks, file uploads, data analysis, image generation, search and study mode are all marked as included on both.
- Unlimited everyday text chats. Free has that too, subject to OpenAI’s abuse guardrails.
If what you want is to paste in a long document and keep a project’s files in one place, Go’s table entries match Plus’s.
What the extra $12 a month buys
The differences are in models, speed and the heavier tools:
- The newest reasoning models. The table gives Plus GPT-6 Sol, GPT-6 Astra and GPT-6.1 Sol, and marks all three as not included on Go. Go gets GPT-6 Luna and GPT-5 Thinking Mini, the same models Free gets.
- Speed. Go’s response times are listed as “Limited on bandwidth & availability”, the same wording as Free. Plus is listed as “Fast”.
- No ads. OpenAI’s ads FAQ says ads may appear on Free and Go, and that Plus and Pro have none. The Go card on the pricing page says the same: “This plan may include ads.”
- Heavier tools. Deep research and Codex are “Limited” on Go and fully included on Plus. Sites is Plus-only. ChatGPT Work is limited and desktop-only on Go, and runs on desktop, web and mobile on Plus.
- Legacy models. Not on Go; included on Plus.
OpenAI’s own pages disagree in two places. The Go help article says Think on Go uses GPT-5.6 Luna, while the comparison table marks GPT-5.6 Luna as not included on Go. And the same help article says OpenAI “may start testing ads in ChatGPT Go in the future”, while the ads FAQ and the pricing page say Go may already show them. We’ve gone with the pricing page and the ads FAQ, and you should assume ads are possible on Go.
The calculation: is Plus worth $144 more a year?
Plus has to save you $144 of time a year more than Go would. Divide that by what an hour of your time is worth:
$144 ÷ your hourly rate = hours a year Plus must save you over Go
At $25 an hour, that’s 5.8 hours a year, or about 29 minutes a month. At $50 an hour it’s 2.9 hours a year.
The question isn’t whether ChatGPT saves you time. Go already gives you that. It’s whether the better model and faster responses save you that much more. For someone using reasoning models for code, analysis or research most working days, 29 minutes a month is easy to clear. If you use it for recipes, emails and settling arguments, it won’t be.
We can’t tell you how many minutes the stronger models save you. We haven’t measured it, and it depends entirely on the work. That’s the number to estimate honestly.
The cheaper way to get Plus when you need it
Both plans bill monthly, and switching is allowed in both directions. When you move from Plus down to Go, OpenAI’s help article says you keep Plus until the end of the billing cycle, then pay the Go rate, with no refund. So switching down early costs you nothing: you keep the month you paid for.
That lets you use Plus only for the months you need it. Say you have three heavy months a year, such as a thesis, a launch or tax season:
| Approach | Calculation | Year |
|---|---|---|
| Plus all year | 12 × $20 | $240 |
| Plus for 3 months, Go for 9 | (3 × $20) + (9 × $8) | $132 |
| Plus for 3 months, Free for 9 | 3 × $20 | $60 |
Switching saves $108 over a year of Plus, and dropping to Free in quiet months saves $180. The catch is that you have to remember to switch. A reminder set the day you upgrade does that. Our annual versus monthly billing guide explains why the lack of an annual plan works in your favour here: you aren’t locked into the expensive tier for a year.
Go against the other cheap AI plans
Go isn’t the only plan under $10. Google AI Plus is $4.99 a month, or $59.88 a year, on Google’s subscriptions page. That’s $36.12 a year less than Go. Our AI subscription comparison explains what it includes and how it relates to Google One storage.
The cheapest plan overall is the one you already pay for. If you pay for Claude Pro, Google AI Pro or another $20 AI plan, adding Go on top is $96 a year for overlap.
Check how you’re actually billed
If you subscribed in the ChatGPT app, you may be billed by Apple or Google rather than OpenAI. OpenAI’s help article on Go mentions App Store and Play Store subscriptions, and we haven’t confirmed that app-store prices match the web prices above. An app-store charge appears under Apple’s or Google’s name, not OpenAI’s, which makes a forgotten second plan easy to miss. Our guide to spotting subscriptions on a bank statement shows what those charges look like.
The verdict
Go is enough if you leave Free because you keep hitting limits on uploads, images or conversation length, and you mostly chat, write and summarise. You get the same context window as Plus for $96 a year instead of $240.
Plus is worth it if you use reasoning models for real work most weeks, such as coding, analysis or research, or you rely on deep research or Codex. It’s also the cheapest way to avoid ads. At $25 an hour, it needs to save you about half an hour a month more than Go to pay for itself. If you need it only some months, pay for those months and drop back to Go the rest of the year.
Don’t buy Go if ads would bother you. Go may show them, and the only ad-free paid plans are Plus and Pro. Paying $96 a year and still seeing ads is a poor trade for anyone who cares about it.
Don’t buy either if you open ChatGPT a few times a week. Free includes unlimited everyday chats. Upgrade when a specific limit actually gets in your way, not before. And don’t add either to an AI plan you already pay for from another company.
