In September 2026 I posted a series of internal announcements on LinkedIn highlighting new product releases, research advances, and strategic partnerships at Perplexity. The posts covered the Rust‑based Photon Search Engine, a fast Search API, tool‑call reliability improvements, the rollout of Claude Opus 5.5, our in‑house CobbleDB database, partnerships with HP and Autodesk, and a Portable Computer that runs locally on Ryzen AI Max PRO hardware.
Photon achieved sub‑250ms p95 latency while still ranking highly on relevance and accuracy benchmarks.
Our new post‑training method cut tool‑call failures by about 21% in live A/B tests.
Claude Opus 5.5 will become the “Standard” Effort orchestrator on Computer for all Pro and Max users.
Migrating to our in‑house database (CobbleDB) will save us up to a hundred million dollars yearly.
The Perplexity Windows app will be pre‑installed on new HP devices, starting with the HP ZBook Ultra G3a.
Portable Computer runs on Ryzen AI Max PRO 400‑series processors for on‑device workflows.
