Perplexity AI users hit unexpected query limits amid promo code abuse claims

Perplexity AI users are experiencing unexpected exhaustion of their advanced AI query limits, with many reporting that their allocated usage drops significantly after just a few queries. The company has responded by attributing the issue to promotional code abuse, stating that some accounts have been flagged for unusual patterns that trigger separate, stricter usage restrictions. Affected users, particularly those relying on reasoning-focused advanced AI models, are being notified that they must upgrade to the higher-tier Max subscription plan (priced at $20/month) to restore full access.

This situation has sparked frustration among users who claim they have not violated any terms. The incident highlights growing pains for AI service providers as they balance aggressive user acquisition through promos with sustainable infrastructure costs. For professionals relying on Perplexity's advanced models for research and analysis, the sudden limits disrupt workflows and erode trust. The company has yet to provide a timeline for resolving the issue or clarify how it distinguishes legitimate use from abuse.
