Published limits
| Plan | Limit | Window | When exhausted | Evidence |
|---|---|---|---|---|
| Tier 0 | 50 per minute sonar / sonar-pro requests | per minute | 429 until the minute rolls | ● Documented |
| Perplexity usage-tiers docs, fetched 2 Aug 2026. Tier 0 is any new account at $0 cumulative spend. | ||||
| Tier 0 | 5 per minute sonar-deep-research requests | per minute | 429 until the minute rolls | ● Documented |
| Deep research is rate-limited an order of magnitude harder than standard search at every tier. | ||||
| Tier 3 | 1,000 per minute sonar / sonar-pro requests | per minute | 429 until the minute rolls | ● Documented |
| Reached at $500 cumulative lifetime spend. | ||||
| Tier 4 | 4,000 per minute sonar / sonar-pro requests | per minute | 429 until the minute rolls | ● Documented |
| Reached at $1,000 cumulative spend. ⚠️ This is the ceiling for standard models — Tier 5 ($5,000) grants NO further increase for sonar, sonar-pro or sonar-reasoning-pro. Spending past $1,000 buys deep-research headroom only. | ||||
| Tier 5 | 100 per minute sonar-deep-research requests | per minute | 429 until the minute rolls | ● Documented |
| Reached at $5,000 cumulative spend; 20× the Tier 0 allowance and the only limit that still rises at this tier. | ||||
| All tiers | Cumulative spend Tier advancement | account lifetime | n/a | ● Documented |
| Tiers are based on cumulative purchases across the account lifetime, not current balance — so a tier is never lost by drawing the balance down. Thresholds: $0 / $50 / $250 / $500 / $1,000 / $5,000. | ||||
| All tiers | Superseded Sonar Chat Completions | n/a | n/a | ○ Observed |
| The docs note Sonar Chat Completions is now the Agent API. Retained here because integrations built against the old surface will still be citing its limits. | ||||
