| Attribute | Cursor | OpenAI Codex | Vapi |
|---|---|---|---|
| Plans | Free Free Trying the editor and a few agent runs. | Free Free A quick look at what it can do. | Pay as you goOur pick $0.05/min hosting, plus provider costs Developers building and testing. |
Plus $8/mo Light users who are happy with Grok models only. | Go $8/mo Occasional light tasks. | Core $29/mo plus usage Builders and early teams going live. | |
PremiumOur pick $30/mo Most developers, especially if you want Claude alongside Grok. | PlusOur pick $20/mo Anyone who already pays for ChatGPT. | Pro 10% of hosting fee, $999/mo minimum Teams running voice agents in production at scale. | |
Super or Ultra $100/mo or $200/mo Heavy daily agent users. | Pro From $100/mo Developers who hit the Plus limits. | Premier Custom Large organisations. | |
Legacy Pro $20/mo Existing subscribers only. New customers can't buy it. | Business $20/user/mo billed yearly, or $25 monthly Teams of 2 or more. | ||
Teams From $30/user/mo Companies that need admin controls and SSO. | Enterprise Custom Large organisations. | ||
| Which plan to pick | If you are on the old $20 Pro plan and it covers what you use, stay put; switching is permanent. New customers should skip Plus unless they are happy with Grok. Premium is the realistic starting point if you want Claude, and budget for the extra usage billing on top of the $30. Large companies can ask about a custom Enterprise plan. | If you already have ChatGPT Plus, you have Codex: just try it. If you are choosing between this and Claude Code with no existing subscription, Plus at $20 and Claude Pro at $20 cost the same, so pick whichever chat assistant you prefer. If you outgrow Plus, Pro starts at $100 and has no five-hour limit for now. The $200 tier gives new subscribers less usage than it used to, and Ultrafast mode is only on the $500 tier. | Build on pay as you go, then add Core when you go live and want email support. HIPAA compliance is a separate $2,000-a-month add-on, so check that early if you work in healthcare. |
