Terra is built for complex goal-oriented work, making it an ideal subagent. On WANDR, Terra scores 11 points above Sonnet while delivering order-of-magnitude cost reductions. Luna handles recurring workflows where speed and cost matter.

GPT 5.6 Terra and Luna are now live in Perplexity Computer. Terra is the new default model for all Computer subagents, while Luna will serve as the primary model for scheduled automations. Terra is also available as an orchestrator model in Computer.

“AI Meltdown” is the scenario where the agent goes off the rails and forgets/ignores all previous instructions and soft guardrails. No prompt injection or malicious actor is needed for this to happen. At @perplexity_ai we built a suite of tools to prevent AI Meltdown from…

Today we're launching Projects, an evolution of Spaces. Projects are hubs for ongoing work in Computer. A single place to manage, create, and collaborate on tasks with a shared file system and persistent memory. Video

Projects connect to Brain, Computer's self-improving memory system. Between tasks, Brain reviews the Project's files and sessions and updates what it knows, so each task starts with full context from previous work.
