Perplexity has moved Deep Research into Computer, its multi-model orchestration system. The upgrade improves accuracy, depth of analysis, and citation quality. Deep Research now breaks hard questions into subtasks and routes them across 20+ frontier models. It returns work-ready reports, decks, and dashboards, all inside Computer.
Deep Research is a mode that runs many searches, reads sources, and writes a cited report. The new version lives inside Perplexity Computer, which launched in late February 2026. Computer is a cloud system that coordinates up to 20 AI models in one workflow. It is model-agnostic, with Opus 4.6 as its core reasoning engine. Sub-agents handle specialized work, such as Gemini for deep research tasks.
Deep Research in Computer is built on two parts: the Agent Search SDK and Search as Code. With one complex question, it builds a research plan automatically. It then finds primary sources across hundreds of sites and cites every claim.
Search as Code: How It Works
The model writes code that assembles the search itself. That code runs thousands of retrieval steps in parallel, tailored to each question. The script runs in a sandbox and calls Perplexity’s Agentic Search SDK. The SDK exposes search primitives such as filtering, deduplication, and reranking. This differs from a fixed pipeline that runs the same steps every time. Code-driven search lets the system branch, compare, and refine as it learns.
