Quick Verdict
ChatGPT Plus at $20/month is a general-purpose AI assistant. Cursor Ultra at $200/month is a high-volume coding agent with $400 of included API budget — 20x the standard Cursor Pro allocation. These plans serve fundamentally different users.
Pricing
- ChatGPT Plus: $20/month. Monthly billing only. Includes Codex and credit top-ups.
- Cursor Ultra: $200/month. Includes $400 worth of API usage per month — effectively 2x the dollar amount you pay.
At 10x the price, Cursor Ultra targets professional developers who generate heavy agent usage daily. The included $400 budget means you are paying $200 for the tooling and getting $200 in API subsidy.
