TL;DR: ChatGPT Go costs $8 a month in the US (£7 on the web in the UK); ChatGPT Plus costs $20 (£20). Both give unlimited everyday text chats. Go adds more images, uploads, data analysis and longer memory than Free, and its “Think” mode runs on GPT-5.6 Luna. Plus adds OpenAI’s advanced reasoning models (GPT-6 Sol, GPT-6 Astra and GPT-6.1 Sol), full deep research, full Codex, interactive charts and early features. Go may include ads; Plus doesn’t. Pick Go for everyday chat, writing help and more image generation; pick Plus if you rely on deep reasoning, research or coding.

OpenAI now sells three consumer tiers: Go, Plus and Pro. The ChatGPT Go vs Plus decision is the one most people face, because the price gap is $12 a month ($144 a year). This guide compares them using OpenAI’s own published plan tables. We haven’t benchmarked the two plans side by side; message caps also change with demand, as OpenAI notes.
What’s the difference between ChatGPT Go and Plus?
ChatGPT Go is a low-cost plan with higher everyday limits; ChatGPT Plus adds OpenAI’s advanced reasoning models and full-strength tools. OpenAI’s Help Center says Go “includes unlimited everyday text chats and higher limits than Free for eligible features such as image generation, file uploads, and data analysis.” Plus, per OpenAI’s Plus article, adds priority access, “higher model limits” and “advanced reasoning access.”

How much do ChatGPT Go and Plus cost in the US and UK?
In the US, ChatGPT Go is $8 a month and ChatGPT Plus is $20 a month, plus sales tax. OpenAI announced the $8 US price when it launched Go worldwide on January 16, 2026, and lists Plus at “$20/month (billed monthly).”
In the UK, price tracker PlanPrice recorded £7.00 for Go and £20.00 for Plus on chatgpt.com on October 21, 2026, including VAT. Apple’s App Store lists £6.99 and £19.99. OpenAI says Go pricing “is localized in some markets” and that it “may adjust pricing over time.”
| Plan | US monthly | US yearly (12 × monthly) | UK monthly (web) | UK yearly |
|---|---|---|---|---|
| Go | $8 | $96 | £7 | £84 |
| Plus | $20 | $240 | £20 | £240 |
| Difference | $12 | $144 | £13 | £156 |
OpenAI’s Go article says it doesn’t support annual billing for Go, Plus or Pro on its own site. PlanPrice reports a yearly Plus option at $200 in Apple’s US App Store, which isn’t offered on chatgpt.com.
Which models do you get with ChatGPT Go vs Plus?
Go doesn’t include OpenAI’s top GPT-6 reasoning models; Plus does. OpenAI’s pricing table marks GPT-6.1 Sol, GPT-6 Astra and GPT-6 Sol as “No” for Go and “Yes” for Plus. Both plans include GPT-6 Luna.
OpenAI’s Go help article adds that Go users “can access Think on the web and in the ChatGPT mobile app,” and that “Think uses GPT-5.6 Luna. ChatGPT Go does not include GPT-5.6 Sol.” Legacy models such as GPT-4o aren’t available on Go either.
In practice, this is the biggest reason to pay for Plus. If you ask ChatGPT to work through multi-step problems, analyze long documents carefully or write code, the Sol and Astra models are what you’re paying for.
Does ChatGPT Go have limits on images and uploads?
Yes, but higher than Free. OpenAI’s launch post said Go gave “10x more messages, file uploads and image creation than the free tier.” Plus has “expanded” limits above that, per the pricing page. OpenAI doesn’t publish exact caps for either plan.
The OpenAI Plus article says Plus “may include usage limits such as message caps, especially during high demand,” and that “these limits may vary based on system conditions.” So neither plan has a fixed, guaranteed image or upload count.
Two image differences are documented: Plus gets “more complex and accurate image creation,” and only Plus includes image generation with Thinking.
Does ChatGPT Go have ads?
It may. OpenAI’s pricing page says the Go plan “may include ads,” and the Go help article says OpenAI “may start testing ads in ChatGPT Go in the future.” Plus isn’t marked as including ads. If an ad-free experience matters to you, that’s a point for Plus.
Is ChatGPT Go good for students?
For essay feedback, study help and everyday questions, yes. For heavy research or coding, Plus is safer. Both Go and Plus include Study mode, projects and file uploads, per OpenAI’s pricing table. Go only has limited deep research and Codex, which students doing long research papers or programming courses will hit first.
Free Study mode also exists, so try the Free plan before paying for either.
Can I switch between Go and Plus?
Yes, in Settings > Account. OpenAI says if you move from Plus or Pro to Go, “your current plan will remain active until the end of your billing cycle” and then switches to the Go rate. OpenAI doesn’t refund the difference. Subscriptions bought through the App Store or Google Play are managed in that store, so cancel there before buying on the web to avoid paying twice.
ChatGPT Go vs Plus: which should you buy?
Buy Go if you mainly chat, write and create images; buy Plus if you need reasoning, research or coding.
| You mainly… | Best plan |
|---|---|
| Ask everyday questions, draft emails, summarize articles | Go |
| Generate lots of images for fun or social posts | Go (Plus if quality matters) |
| Analyze long reports, contracts or data carefully | Plus |
| Run deep research for work or school | Plus |
| Write or debug code with Codex | Plus (or Claude Code vs Codex) |
| Want no ads | Plus |
| Hit Plus limits regularly | Pro |

Verdict
ChatGPT Go at $8 (£7) is the best value for people who use ChatGPT as an everyday assistant and want more images and uploads than Free. ChatGPT Plus at $20 (£20) is worth the extra $12 a month only if you use the GPT-6 reasoning models, deep research or Codex regularly. When in doubt, start with Go; you can upgrade instantly.
