| Which plan to pick | The free plan is now good enough to use properly, so stay on it until the image, voice or research limits annoy you. Plus is the sensible upgrade. Only look at Pro if you run Codex or deep research all day, and read the current tier details first: Pro 200 now comes with a smaller allowance than it did before 29 September. | The free plan is enough to see if the speed and tone suit you. Pro is good value at $14.99 and a sensible second assistant next to Claude. Students can get Pro for $5.99 a month for up to 12 months. | 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. |
