ChatGPT review

ChatGPT review cover graphic

ChatGPT is OpenAI’s AI assistant, and for many people it is the tool that defines what an AI chatbot is. It now comes in a ladder of plans, from a free tier through a low-cost Go plan to Plus, Pro, Business and Enterprise, with different limits, models and tools on each step.

This review sets out what OpenAI documents about those plans, which prices we could verify, how usage limits work, and what is and is not clear about data use. It is written for individuals and small teams choosing a plan, and it flags where OpenAI’s own pages disagree with one another.

How we researched this: we did not run hands-on tests for this article. It is based on the vendor’s own documentation and public sources, checked on 11 November 2026. Features and prices change, so confirm details on the vendor’s site before you buy.

Key takeaways

  • OpenAI’s plan ladder, as listed on its pricing page, is Free, Go, Plus, Pro, Business, Enterprise and Education. The page we read showed no dollar amounts, so prices below come from OpenAI help and announcement pages.
  • Prices we could verify: Go at $8 per month in the US, Plus at $20, and Pro at $100 or $200 for 5x or 20x the usage of Plus. Business seats are $25 monthly or $20 on annual billing for standard, $125 or $100 for premium.
  • Limits are described in message windows. OpenAI’s help page says Plus and Go allow up to 160 messages every 3 hours on its default model before switching to a mini model.
  • OpenAI says Go may include ads and that it may test ads in Go in the future. Annual billing is not offered for Go, Plus or Pro.
  • OpenAI says Business data is not used for training by default. We could not confirm the consumer default from the pages we could open, so check the data controls yourself.

What it is

ChatGPT is a chat-based assistant that can answer questions, write and edit text, analyse files, create images, do research and, on higher plans, run longer tasks with tools. OpenAI’s pricing page lists a ladder in which each plan builds on the one below. It also lists Codex (OpenAI’s coding tool) and a feature called ChatGPT Work on several plans.

Underneath, ChatGPT uses large language models that predict text, which is why they can sound sure of themselves when they are wrong. If that idea is new, read what is a large language model.

A note on model names

OpenAI’s pages did not agree on which models are current when we checked. The pricing page lists a GPT-6 and GPT-5.6 family, while a help article on models in ChatGPT describes GPT-5.5 Instant, Thinking and Pro and says GPT-5 was retired on 13 February 2026. The help page showed only a relative update time. Model names and limits move quickly, so we describe plan structure rather than ranking models, and you should check which model your plan uses.

Who it is for

  • Casual users who want a general assistant: Free or Go may be enough.
  • Regular users who want reasoning models, deep research, projects, custom GPTs and scheduled tasks: Plus is described as designed for advanced users.
  • Heavy users who hit limits or want the highest-capability model: Pro offers higher tiers.
  • Teams that need shared workspaces, admin controls and data protections: Business, from two users.
  • Large organisations and universities: Enterprise and Edu, which are sold through sales.

What Go adds

OpenAI’s help centre says Go includes near-unlimited chat on its Instant model subject to guardrails, higher limits than Free for core chat and tools, extended image generation, uploads and data analysis, longer memory and a larger context window, projects, tasks and custom GPTs, up to 4 GB of library storage, and reasoning. It does not include legacy models, Sora or API usage, and some apps require Plus or higher.

What Plus adds

The help page says Plus adds expanded access to thinking and legacy models, plus deep research and agent mode. Sora access starts at Plus. OpenAI’s separate Plus help article describes it as a subscription offering better availability during high demand, faster responses and early access to new features. The API is billed separately and is not included in any consumer plan.

Pricing model

Checked on 11 November 2026. OpenAI’s pricing page showed no dollar amounts in the text we could read, so these figures are from OpenAI help and announcement pages. Confirm the live prices before you buy.

Billing rules worth knowing

  • Annual billing and paying several months in advance are not supported for Go, Plus or Pro, per OpenAI’s help page.
  • Upgrades take effect immediately and restart the billing cycle. Downgrades take effect at the next renewal. Moving from Plus or Pro to Go gives no refund.
  • For Plus, cancelling takes effect the day after the next billing date, and OpenAI advises cancelling at least 24 hours before it. Subscription fees are otherwise non-refundable, except that users in the EU, UK or Turkey can request a refund if they cancel within 14 days of purchase.
  • The pricing page mentions three Pro usage tiers and monthly API credits, while the help article we read describes only the $100 and $200 tiers. We could not confirm the price of a third tier.
  • Business usage is described as unlimited subject to abuse guardrails, and OpenAI says usage will be pooled across ChatGPT and Codex starting in December.

Strengths

  • A wide entry range. Free, Go and Plus let you step up gradually.
  • Breadth of tools. Research, projects, custom GPTs, scheduled tasks, images, voice and an agent mode are documented across plans.
  • Clear usage windows on some plans. OpenAI’s help page gives message windows, such as up to 160 messages every 3 hours for Plus and Go, and 10 Thinking messages every 5 hours for Go.
  • Team integrations. Business lists integrations with common workplace tools and admin controls such as SAML, SSO and MFA.
  • A coding tool in the same account. Codex is listed across plans.

Limits and cautions

Caution Detail
Ads on Go OpenAI’s help page says it may test ads in Go in the future, and the pricing page says Go may include ads.
Dynamic limits Free limits are dynamic within a five-hour window. OpenAI says limits may vary with system conditions.
No way to raise a cap On Pro, when a model allowance is reached, the model is unavailable until it resets. OpenAI says there is no setting to bypass it.
Guardrails Abuse guardrails can cause temporary restrictions, and the terms prohibit credential sharing and reselling access.
Context windows The help page lists smaller context for Free (16K) than Plus and Business (32K) or Pro and Enterprise (128K) on the Instant model.
Inconsistent pages Model names and tiers differ between OpenAI pages.
Errors Answers can be wrong. See AI hallucinations: what they are and how to reduce them.

Privacy and data

OpenAI’s business pricing page says Business data is not used for training by default. For individual Free, Go, Plus and Pro accounts, we could not open an OpenAI page that states the default for chat content, so we do not state it here. Look for the data controls in your account settings and any temporary chat option, and read OpenAI’s current privacy policy before putting sensitive material into a personal account.

  • Personal accounts: confirm the training setting and retention in settings before first use.
  • Business and above: confirm the written terms and admin controls.
  • Memory: Go and higher plans include longer memory, which means more personal context is stored. Review and delete what you do not want kept.
  • Ads on Go: read how ad personalisation would work if it appears.

Alternatives

Who should and should not use it

Best for you if

  • You want one assistant for writing, research, images and files and can pick a plan that matches your usage.
  • You are happy to start on Free or Go and move up once you hit limits.
  • Your team needs shared workspaces and admin controls on Business.

Look elsewhere or take care if

  • You dislike ads and are considering Go.
  • You need a written commitment about data handling and are considering a personal plan.
  • You want annual discounts on individual plans, which OpenAI says it does not offer.

Questions to ask before buying

  1. What is the current price in my country and currency?
  2. Which model do I get on my plan, and what are the message windows?
  3. Is chat content used for training by default, and how do I change it?
  4. Do I need Business for admin controls, and how many seats?
  5. If I need Pro, which usage tier and price apply?
  6. How will ads, if any, appear, and can I avoid them?

Conclusion

ChatGPT’s documented strength is range: a free tier, a cheap Go plan, Plus for regular users, Pro for heavy use and Business for teams. The documented cautions are ads on Go, usage windows that vary by plan, pages that disagree on model names, and an unclear picture of consumer data defaults on the pages we could read.

Before paying, confirm the live price and the data controls, and test with your own work. For context on choosing, start with how to choose an AI tool.
