| Which plan to pick | The app is free, so the only decision is whether the privacy trade-off is acceptable for what you're asking. If you need the model inside your own software, have a developer use the API or run the open model through a provider that keeps your data in Australia. | Start free. If you're putting anything sensitive in or building something people will use, switch to a paid API key so your prompts aren't used for training. Google AI Pro only makes sense if you'd use the Gemini app upgrade too. | Start free and see how often you hit the Pro search limit. If you research most days, Pro pays for itself in saved tabs. Its 4,000 bonus Computer credits are a one-off and run out after about 30 days, so don't count them as a monthly allowance. Max only makes sense if you're using the Computer agent heavily enough to burn through the credits. |
