ChatGPT Pro 500: $500/monthChatGPT Pro 500 covers about 10k turns of balanced coding work a month, 21 per dollar. That is the 3rd most of the 37 plans with a usage figure. At $500 or less, Claude Ultra covers the most: about 13k.
What it includes
| Price | $500/month |
|---|---|
| Coding agent | Codex |
| Limit, as OpenAI words it | No five-hour limit. 50× Plus, per OpenAI's Codex lead on 8 November 2026. |
| Usage at API prices | $8k–$15k a month, 16–30× the price |
| Evidence | Derived · checked Nov 12, 2026 |
| Strongest model | GPT-6 Astra, 56.9 on the Intelligence Index |
Models
- GPT-6 Astra · up to 56.9
- GPT-6.1 Sol · up to 54.6
- GPT-6.1 Terra · up to 51.3
- GPT-6 Luna · up to 27.9
Value by kind of work
Turns of mixed coding work the allowance covers in a month, each kind on the plan’s cheapest model that is good enough. How this is worked out.
| Work mix | Turns a month | Per dollar |
|---|---|---|
| Light only (100% light) | 100k–187k | 200–375 |
| Mostly light (40% normal, 60% light) | 51k–95k | 101–189 |
| Balanced (5% frontier, 15% hard, 60% normal, 20% light) | 7.6k–14k | 15–28 |
| Mostly hard (10% frontier, 40% hard, 40% normal, 10% light) | 4k–7.5k | 8–15 |
On the balanced mix: frontier work on GPT-6.1 Sol (max reasoning), counting 4% of a turn; hard work on GPT-6.1 Sol (max reasoning), counting 50% of a turn; normal work on GPT-6.1 Terra (xhigh reasoning); light work on GPT-6 Luna (max reasoning), counting 55% of a turn.
