Perplexity Launches Brain to Teach Its AI Agents From Real Work

Perplexity has launched Brain, a self-improving memory system for its Computer agents that learns from past work, user corrections and task outcomes to improve future performance. Rolling out to Max and Enterprise Max subscribers, Brain builds a living context graph that helps agents find better sources, avoid mistakes and complete tasks more efficiently. Perplexity says the system improves answer correctness by 25%, boosts recall by 16% and reduces context-related task costs by 13%.
