|---|---|---|---|
| Plans | ProOur pick $20/mo, or $17/mo billed yearly Anyone trying browser tasks for the first time. | ChatGPT ProOur pick $100, $200 or $500/mo Heavy ChatGPT users outside Europe who want a personal agent. | Free Free Everyone. There is no paid tier for the AI. |
Max $100/mo People running browser tasks most days. | Business Premium $100/seat/mo billed yearly, or $125 monthly Teams that want dots in every supported country. | Free with an Opera accountOur pick Free Anyone who wants chat history across devices and more images. | |
Ultra $200/mo All-day agent users. | Enterprise and Edu Custom Large organisations testing agents under admin control. | ||
Team From $20/seat/mo billed yearly, or $25 monthly Teams of 2 to 150 who want admin control. | |||
Enterprise From $20/seat/mo yearly plus usage, 20-seat minimum Larger companies with security rules. | |||
| Which plan to pick | Pro is enough to see what it can do for you. Browser tasks use your limits faster than chat, so if you hand it real work every day you'll likely need Max. Teams should use the Team plan so an admin can control which sites Claude can use. | Pro 100 is the cheapest way in for one person, and the bigger Pro tiers don't give you a better dot, just more room for the work it runs. If you're in the UK or Europe, or you want dots for staff, Business Premium is the only option. Don't upgrade from Plus just to try it until OpenAI publishes the usage terms that apply after the launch month. | It's all free. Sign in with a free Opera account if you want your chats saved and more images; otherwise just download it and click Ask AI. Opera sells a separate VPN Pro, but you don't need it for the AI. |
