| Which plan to pick | 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. | Use it free: the sidebar assistant alone is worth having, and most people never need more. Pro makes sense if you want Perplexity's research tools anyway, but don't buy it just for the browser agent, since Pro's credits are a one-off bundle. Nobody needs Max just for the browser. |
