Pros

• ✓Perplexity both publishes MCP servers, one for its search and research tools and one that hands tasks to Computer, and consumes external MCP servers through its Agent API, so it can feed cited research into other AI tools and pull third-party tools into its own runs.
• ✓Paid plans let users choose between frontier models including GPT-6.1 Sol, Gemini 3.8 Flash, Claude Sonnet 5.5, Kimi K3, GLM 5.3 and Grok 4.7, and Effort Mode can pick the model and reasoning level for each Computer task.
• ✓Every answer carries inline citations, and Computer extends the same sourcing into Microsoft 365 documents and autonomous multi-step web tasks on all paid plans.

Limitations

• –Perplexity ended support for its original Sonar Chat Completions API on September 27, 2026. Synchronous and streaming requests are being reformulated as Agent API requests, but asynchronous Sonar requests are no longer supported and must move to background mode.
• –The terms limit every plan below Enterprise, including Free, to personal, non-commercial use, so business buyers need Enterprise seats from $34 per seat per month billed annually, and SCIM, audit logs and data retention settings start at Enterprise Max or a custom-priced plan.
• –Consumer searches are used to improve Perplexity's models by default and the opt-out must be set manually in account settings, while the no-training commitment applies only to Enterprise plans.
