Perplexity Adds Claude Sonnet 4.5 Models for Pro and Max.

Perplexity has made Claude Sonnet 4.5 and Claude 4.5 Thinking available to Perplexity Pro and Max subscribers. The update expands the range of AI models accessible inside Perplexity’s paid plans, giving users more choice when deciding how to run searches, research tasks, and other AI-assisted workflows.

Key details:

• Claude Sonnet 4.5 is now available for Perplexity Pro subscribers.
• Claude 4.5 Thinking is also included for eligible paid users.
• Access is limited to Perplexity’s Pro and Max tiers.
• The announcement was shared by Perplexity on LinkedIn on September 29, 2025.
