| Which plan to pick | Start with the 14-day trial. Essentials is enough for most small teams; you only pay for developers who open pull requests. Turn on usage-based reviews ($0.25 a file) with a monthly cap if you keep hitting the hourly limit. | If you already pay for X, try it on the plan you have. Premium at $30 a month is the sensible level for regular coding, but if you're choosing a coding agent from scratch, Claude Code or Codex are the safer picks today. Plans changed on 12 October 2026, so check x.ai before you buy. | Personal. If you have Claude Pro, run Claude Code inside Zed and you are done. Pro only makes sense if you want Zed's built-in assistant and edit predictions without setting up API keys. |
