Perplexity AI usage limits spark serious backlash amid promo code crackdown

Perplexity AI usage limits are at the centre of a growing dispute between the company and some of its paying users.

Subscribers have reported that their weekly advanced AI usage limits are being exhausted far more quickly than before, sometimes after only a handful of queries or file uploads. Many say they are seeing "weekly usage limit exceeded" pop-ups despite what they describe as light, everyday use of premium, reasoning-focused models.

On social media and online forums, several Perplexity Pro customers claim they are hitting caps after just a few advanced prompts per day, and that upload limits for documents appear stricter than in previous months. Some users also believe token allowances and overall advanced model query caps have quietly tightened, even though their subscription plans and invoices remain unchanged.

Perplexity acknowledges that some accounts are subject to different enforcement, particularly those tied to promotional-code subscriptions. In a statement to Android Authority, a company spokesperson said: "Some users are seeing different usage limits because their accounts are tied to promotional-code offers, and we've had to adjust enforcement due to fraud and unauthorized resale of those codes, including cases where people may have unknowingly purchased invalid codes from third parties."

The company says it is working to make applicable limits clearer for affected users and has urged anyone who believes they were wrongly impacted to contact customer support for help, while it continues to enforce its terms against abuse. Perplexity also stresses that standard AI models on the platform are not affected by these stricter caps.

Reports suggest that when users hit the new limits on advanced AI models, they are prompted to upgrade to Perplexity's higher-tier Max subscription, which offers much looser constraints for heavy usage. That has fuelled criticism that legitimate customers on discounted or promo-based plans are being pushed towards a more expensive tier without adequate communication.

Perplexity has not publicly updated its pricing or usage documentation to reflect any broad change in limits, nor has it confirmed whether enforcement differs by region, despite speculation that some countries may face stricter controls than the United States. Until the company clearly sets out how Perplexity AI usage limits work across plans, and how promo code subscribers are treated, trust is likely to remain strained between the fast-growing AI service and a vocal segment of its user base.
