Google AI Pro: $19.99/month
Google AI Pro: $19.99/monthGoogle AI Pro covers about 293 turns of balanced coding work a month, 15 per dollar. That is the 14th most of the 37 plans with a usage figure. No plan at $19.99 or less covers more.
What it includes
| Price | $19.99/month |
|---|---|
| Coding agent | Antigravity |
| Limit, as Google words it | A quota that refreshes every five hours until a weekly limit, plus a separate, small weekly Argon quota. No size is published. |
| Usage at API prices | $517–$536 a month, 26–27× the price |
| Evidence | Measured · checked Nov 12, 2026 |
| Strongest model | Opus 5.5, 59.1 on the Intelligence Index |
Models
- Gemini 3.8 Flash · up to 30.8
- Gemini 4 Hydrogen · up to 53.9 · Rolled out 12 Nov 2026; its quota rate is unknown, between Flash’s and Argon’s
- Gemini 4 Argon · up to 50.4 · Separate weekly quota, read once at about $7–9 a week; not valued
- Claude Opus 5.5 · up to 59.1
- Claude Sonnet 5.5 · up to 54.5
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) | 1.8k–1.9k | 90–94 |
| Mostly light (40% normal, 60% light) | 833–1.7k | 42–83 |
| Balanced (5% frontier, 15% hard, 60% normal, 20% light) | 169–508 | 8.5–25 |
| Mostly hard (10% frontier, 40% hard, 40% normal, 10% light) | 95–292 | 4.7–15 |
On the balanced mix: frontier work on Gemini 4 Hydrogen (xhigh reasoning), counting 3% of a turn; hard work on Gemini 4 Hydrogen (xhigh reasoning), counting 39% of a turn; normal work on Gemini 4 Hydrogen (high reasoning); light work on Gemini 3.8 Flash (medium reasoning).
How the figure was obtained
Measured: Pro's shared Gemini pool read against logged tokens priced at Gemini list rates, twice (Real API Pricing, September 2026), $119–123 a week. Gemini 3.8 Flash draws on it at API prices. Hydrogen is a day old and its rate is unknown; its range runs from a third of the pool to all of it. Claude models in Antigravity have their own unpublished limit and are not valued.
