Cerebras Systems and Perplexity AI are joining forces to challenge the dominance of conventional search engines. The collaboration centers on Perplexity’s new Sonar model, which runs on Cerebras’s specialized AI chips at 1,200 tokens per second—making it one of the fastest AI search systems available. Built on Meta’s Llama 3.3 70B foundation, Sonar represents a significant bet that users will embrace AI-first search experiences if they’re fast enough.
