Perplexity has updated its Deep Research feature to run on Opus 4.6, according to a LinkedIn post published on 9 February 2026. The company says the model upgrade improves its existing results across both internal and external benchmarks. Access is available immediately for Max users, with a gradual rollout planned for Pro users.
