| 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. | Skip the free plan for anything serious now that it's Flash-Lite only. AI Pro is the one to buy: it's the cheapest way to get Gemini 4 Argon plus Gemini in Docs and Gmail, and the 5 TB of storage offsets a Google One bill. Ultra is for people generating video all day. | Don't buy a plan for Astra alone. If you're on Plus, try it in Codex first. Move to Pro only if you've got real computer-use or long agent jobs for it, and start on the $100 tier. For most writing and research, GPT-6.1 Sol or the standard models are faster and good enough. |
