We've upgraded Deep Research in Perplexity.

Perplexity Deep Research achieves state-of-the-art performance on leading external benchmarks, outperforming other deep research tools on accuracy and reliability.

Available now for Max users. Rolling out to Pro in the coming days. https://t.co/8RAlewuWa3

This upgrade pairs the best available models with Perplexity's proprietary search engine and sandbox infrastructure.

Deep Research now runs on Opus 4.5 for Max and Pro users. We'll upgrade to top reasoning models as they become available. https://t.co/zqbjyObX9T

We're also releasing a new open-source benchmark for evaluating deep research agents.

The Deep Research Accuracy, Completeness, and Objectivity (DRACO) Benchmark is grounded in how people actually use deep research.

Most benchmarks test isolated skills like fact retrieval or trivia. But real research requires synthesis across many sources, nuanced analysis, and accurate sources.

DRACO includes 100 tasks across 10 domains—Academic, Finance, Law, Medicine, Technology, General Knowledge, UX https://t.co/XYNS2A5x15

In our own DRACO evaluations, Perplexity outperforms all competitors in every domain, especially on Law, Medicine, and Academic use cases. https://t.co/tjiRMy84JV

Our DRACO Benchmark is fully open-source and we're releasing the benchmark, rubrics, and methodology today.
