In September 2026 I posted a series of updates on X about Perplexity’s new open‑source embedding model, a free email‑based Computer service, the rebranding of Tasks to Automations, sandbox red‑team findings, and the performance of our new Photon search engine.

The open‑source embedding model **pplx‑embed‑v2‑context‑9b‑preview** set a new state‑of‑the‑art on ConTEB and Turbopuffer’s private context‑bench.

I announced free email‑based Computer access – just **Send, forward, or cc computer@perplexity.com** on any thread – with no Perplexity account required (limited‑time offer).

We renamed the legacy “Tasks” concept to **Automations**, describing them as ongoing work that can trigger on events or schedules.

Our sandbox red‑team ran **0/108** VM escape attempts, confirming the isolation of nine models given full root inside SPACE.

Fast Search on the new Rust‑based **Photon** service delivered a p95 latency of **230 ms** (p50 160 ms).
