ChatGPT Plus: $20/month
ChatGPT Plus: $20/monthChatGPT Plus covers about 207 turns of balanced coding work a month, 10 per dollar. That is the 18th most of the 37 plans with a usage figure. At $20 or less, Claude Pro covers the most: about 1.1k.
What it includes
| Price | $20/month |
|---|---|
| Coding agent | Codex |
| Limit, as OpenAI words it | Local Codex messages per five hours: 5–45 on GPT-6 Astra, 15–160 on GPT-6.1 Sol, 35–285 on GPT-6.1 Terra, 350–3,000 on GPT-6 Luna. Weekly limits may apply. |
| Usage at API prices | $160–$300 a month, 8–15× the price |
| Evidence | Measured · 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) | 2k–3.7k | 100–187 |
| Mostly light (40% normal, 60% light) | 1k–1.9k | 51–95 |
| Balanced (5% frontier, 15% hard, 60% normal, 20% light) | 151–284 | 7.6–14 |
| Mostly hard (10% frontier, 40% hard, 40% normal, 10% light) | 80–151 | 4–7.5 |
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.
How the figure was obtained
Range from three independent measurements of real usage valued at API list prices: wokey.ai ($46 a week, November 2026), finopsllm (median $67 a week, October 2026) and SemiAnalysis ($162–211 a month, October 2026). A derivation from OpenAI's published five-hour message limits gives the same range. OpenAI moves to a shared token allowance in December 2026, after which this needs re-measuring.
