Which plan to pickStart on Free to see if the writing suits you. Most people who stick with it move to Pro within a month; only go to Max if you hit the Pro limits every day or you're running Claude Code for hours at a time.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.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.

Pros and cons

AttributeClaudeGPT-6 AstraGoogle Gemini
Pros
  • Writing sounds like a person and needs the least editing of any assistant
  • Handles long documents and messy briefs without losing track
  • Projects and memory mean you stop repeating the same context
  • Artifacts turn answers into real documents, slides and small apps
  • One subscription covers Claude Code as well
  • The strongest computer-use and agent model available
  • Works through long jobs without hand-holding
  • Included in paid ChatGPT plans rather than sold separately
  • Best coding results of any OpenAI model to date
  • Reads and acts on your Gmail, Docs and Drive directly
  • AI Pro bundles the top model, Workspace features and 5 TB of storage for one price
  • Deep Research is included even on the free plan
  • Fast, and the mobile and Android experience is polished
  • Video and image generation included on paid plans
Cons
  • Free and Pro usage limits can bite on a busy day
  • No video generation, and image generation is basic next to ChatGPT
  • Fewer third-party connectors and plugins than ChatGPT
  • Only on paid plans, and full access needs Pro from $100 a month
  • Slower and far more expensive per token than the standard models
  • Already overtaken for most tasks by the cheaper GPT-6.1 Sol
  • Computer use is still fiddly and results depend heavily on your setup
  • Rollout and plan access keep changing, so what you get varies week to week
  • Free plan is now Flash-Lite only, so it's weaker than the free tiers of ChatGPT or Claude
  • Plan names and model access keep changing, which is confusing
  • Writing quality sits behind Claude and the answers can be padded
  • Workspace features need a personal Google account or a Workspace admin to turn them on
