| 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 because they keep changing. | 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. | 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. |
