Perplexity CEO Says Fable Leads Frontier Models

Aravind Srinivas, co-founder and CEO of Perplexity AI, posted that Fable ranks as the top frontier model available. He advised enjoying its capabilities on Perplexity Computer, where it acts as an orchestrator for high-stakes tasks. The product continues to rely on GPT 5.6, referred to as Terra models, for cost-efficient subagents. This approach lets the system benefit from Fable's strong planning abilities in key areas. The statement appears in a public post on X from the executive's account.
