Which plan to pickStart 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.For chat, it's free. Developers should start with Coding Plan Lite and code off-peak, because usage between 2pm and 6pm Singapore time on weekdays costs more credits. Move to Pro only if you hit the weekly cap.
