ChatGPT

What is ChatGPT?

ChatGPT is OpenAI's AI assistant for writing, research, coding and everyday questions. Most people only need to decide one thing: which of the four personal plans (Free, Go, Plus or Pro) covers how they actually use it. Paying for Plus by default is the most common way to overpay.

Is there a ChatGPT promo code?

Not a public one. OpenAI does not publish coupon codes for Plus or Go. The only codes that exist are referral invites and promotional codes that OpenAI itself sends to eligible accounts by email, inside the app or at its events. They are single use, cannot be stacked and, under OpenAI's terms, cannot be sold or transferred. A site or video selling a "ChatGPT Plus code" is selling something you should not buy.

The legit way to pay less: ChatGPT Go

Go costs $8 a month in the US, against $20 for Plus. That is $12 a month, or $144 a year, saved. Go keeps unlimited everyday text chats and raises the Free limits for file uploads, image creation, data analysis and memory. It also includes Think, OpenAI's reasoning mode, which on Go runs on GPT-5.6 Luna. Go is sold in every country where ChatGPT works, and some countries get a local price instead of USD.

What you give up on Go

Go may show ads. OpenAI started testing ads in the US on February 9, 2026, on the Free and Go plans only; Plus, Pro, Business, Enterprise and Edu have none. Go also lacks the advanced GPT-6 reasoning models, the expanded deep research and Codex limits, and the full ChatGPT Work access that Plus gets, and legacy models such as GPT-4o are not included. Voice mode on Go has the same limits as Free.

Annual billing, Business seats and refunds

There is no annual plan for Go, Plus or Pro: OpenAI's help center says it does not support yearly billing or paying several months ahead for these plans. Yearly billing exists only on Business, where a Standard seat costs $20 per user per month billed annually or $25 monthly, for teams of 2 to 200 people. If you downgrade from Plus to Go, your Plus access runs until the end of the paid month and there is no partial refund.

Which plan should you pick?

Start on Free; it already has unlimited text chats. Move to Go if you hit the upload, image or memory limits and can live with ads. Pay for Plus only if you rely on the advanced reasoning models, deep research, Codex or an ad-free workspace, and look at Pro (from $100 a month) only for heavy daily research or coding.
