Perplexity Computer adds effort controls for model selection

Perplexity added effort controls to Computer, letting users choose Light, Standard, High or Ultra while the service selects the coordinating model and reasoning level. Custom model controls remain available. Perplexity says lower settings use less expensive models and credit usage depends on work performed. The controls are available on web, with Android and iOS planned. Source: Perplexity, September 17, 2026.
