ChatGPT Plus is most likely to be worth it if you use ChatGPT most days for work, study or coding. At $20 a month it removes ads, moves you to GPT-6 Sol (Free and Go get GPT-6 Luna) and gives you more room for files, images, voice and Codex. If you use it now and then, start with the free plan or the $8 Go plan and see whether you run into their limits. Pro, from $100 a month, raises those limits further.

What each plan costs
- Free: $0.
- Go: $8 a month.
- Plus: $20 a month.
- Pro: three tiers at $100, $200 and $500 a month.
OpenAI adds tax where required, and paid plans renew automatically. It doesn't offer standard annual billing for Go, Plus or Pro.
Free and Go can show ads, Plus and Pro don't
OpenAI began testing ads in the US in February 2026. Ads can appear on the Free and Go plans, while Plus and Pro have none. Free users can switch to an ad-free mode at no cost, but it lowers usage limits and can remove tools such as image generation and deep research.
Models and reasoning
OpenAI's October 2026 GPT-6 announcement says Plus and Pro get GPT-6 Sol, while Free and Go get GPT-6 Luna. Plus also gets medium and high reasoning levels, and Pro adds higher ones, including GPT-6 Astra for the Pro reasoning setting. Even Pro has limits on its top model: OpenAI says a Pro plan doesn't include unlimited use of GPT-6 Pro.
Everyday text chats are listed as unlimited on every plan, within OpenAI's fair-use rules. The difference shows up in the tools and the heavier models.
Memory, files and projects
- Context: the pricing table lists a 27K context window for Free, 54K for Go and Plus and 128K for Pro on the Instant model, and 256K for Go and Plus versus 400K for Pro on reasoning.
- Uploads: Free is limited to three file uploads a day. Audio uploads need a paid plan.
- Projects: up to 5 files per project on Free, 25 on Go and Plus, and 40 on Pro.
Images, voice and Codex
Every plan can create and edit images, but Images with Thinking is listed only for Plus and Pro among personal plans. Pro is listed with unlimited, faster image creation, within abuse limits.
For live voice, OpenAI's voice page lists three hours per rolling 24 hours on Plus, 15 hours on the $100 Pro tier and unlimited use on the $200 tier. OpenAI's pages disagree on Go: its Go help page says voice limits match Free, while the voice page lists three hours.
Codex, OpenAI's coding agent, is included on every plan. Plus adds Codex in the cloud for eligible accounts and more usage, with five-hour and weekly limits. The Pro tiers have weekly allowances and no five-hour cap.
What Pro adds
Pro starts at $100 a month and adds the highest reasoning settings, the largest context, unlimited faster image creation and longer Work and Codex sessions. Eligible Pro subscribers can also claim API credits worth $100, $200 or $500 a month, depending on the tier, after at least seven paid days, with the first month prorated. Only the $500 tier includes OpenAI's Ultrafast option.
Cancelling and refunds
On the web, cancel in Settings, then Billing. If you subscribed through Apple or Google Play, cancel in that store. Cancel at least 24 hours before the billing date to avoid the next charge, and you keep access until the end of the paid period. OpenAI says payments are generally non-refundable, with exceptions for billing errors and some other cases.
Who should skip Plus
If you use ChatGPT a few times a week and don't mind ads or lower limits, Free may be enough. Go at $8 raises the Free plan's limits without removing ads.
