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 the largest Cursor usage pool (50x Plus, 12.5x Premium). The older Ultra plan is legacy, with the same role and price for existing subscribers. These plans serve fundamentally different users.
Pricing
- ChatGPT Plus: $20/month. Monthly billing only. Includes Codex and credit top-ups.
- Cursor Ultra: $200/month, excluding tax. One weekly pool for Cursor models (Grok 4.7, Grok 4.6, Grok 4.5, Composer 2.5), shared with Grok, plus Cloud Agents, Automations, Origin and Bugbot.
At 10x the price, Cursor Ultra targets professional developers who generate heavy agent usage daily. Claude, GPT and Gemini are not included and are billed at API list price from prepaid credit.
Model Access
- ChatGPT Plus provides GPT-6 in chat, GPT-6 Astra in ChatGPT Work and Codex, and legacy models. Context window: 54K tokens on GPT Instant and 256K on GPT Reasoning.
- Cursor Ultra includes Cursor models only. Third-party models (Claude, GPT, Gemini) are available at API price.
Cursor Ultra reaches every major provider in one IDE, but the subscription itself covers only Cursor models.
Usage Limits
- ChatGPT Plus offers unlimited* chat with dynamic guardrails. Advanced features use credits.
- Cursor Ultra has one weekly pool for Cursor models, 50x Plus.
Third-party model spend is separate and shows up as API charges against your credit.
