| Plan | Limit | Window | When exhausted | Evidence |
|---|---|---|---|---|
| AI Plus | 2× free tier Compute allowance | refreshes every 5 hours | Blocked until refresh, or until the weekly cap clears | ⨯ Undisclosed |
| Google switched from daily prompt counts to compute-based limits at I/O 2026. The multiplier is published; the underlying unit is not. | ||||
| AI Pro | 4× free tier Compute allowance | refreshes every 5 hours | Blocked until refresh, or until the weekly cap clears | ⨯ Undisclosed |
| Limits factor in prompt complexity, features used and chat length — none of which Google quantifies. | ||||
| AI Ultra | 20× AI Pro Compute allowance | refreshes every 5 hours | Blocked until refresh, or until the weekly cap clears | ⨯ Undisclosed |
| AI Ultra repriced to $100/month in May 2026. | ||||
| AI Pro | 400 per day Daily prompts — HISTORICAL | superseded May 2026 | No longer in force | ○ Observed |
| Retained deliberately: 300 Thinking + 100 Pro prompts per day was the rule before I/O 2026. Readers still arrive holding this number. | ||||
