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.
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.
multi-agent — Using several AI agents on one problem — splitting work in parallel, checking each other, or filling different roles like planner and reviewer.
benchmark — A standard public test set for comparing AI models — the shared scoreboards behind every "model X beats model Y" claim.
