Perplexity’s newest update makes a clear statement: it is no longer just an answer engine, but a persistent work system. With Brain, the Computer agent can build a private context graph across sessions, connectors, files, and past decisions so it remembers what worked before and adapts faster over time. [12]
The same release also improves the agent’s core execution layer. Perplexity added faster Opus 4.8 Fast mode, Claude Fable 5 orchestration, and mid-task model switching, which should make longer workflows feel more responsive and less rigid when tasks change direction. [12]
What stands out most is the move from finding information to acting on it. One-click website publishing to a .pplx.app address or a custom domain turns Perplexity into more than a research tool, while the new private company research feature shows how the platform is expanding into higher-value professional workflows.
