When a step needs the live web or frontier reasoning, the orchestrator stops and asks before sending that single step to one of 15+ cloud models.

Is it deployable?

Yes, with a hard hardware gate. This is shipping software, not a preview binary, but it needs a GB10-class box or an RTX GPU with 24 GB of VRAM under the desk.

Company level: Enterprises and mid-market teams that already own NVIDIA workstations, plus well-funded AI-native startups. Not viable for general SMBs — the machine is the price of entry.

Industries: Finance, legal, healthcare, government and defense, and IP-heavy engineering — anywhere data residency or contractual confidentiality blocks cloud inference.

Applications: Fee and disclosure review across document sets, PII-bounded research, repo-scale migrations, batch summarization of local corpora, and PR triage that ends in Slack.

What actually ships on the device

Portable Computer is not a local chat app with a file picker. Perplexity packages the local model, inference engine, agent harness, tool sandbox and app connectors as one system, which removes the usual work of standing up an inference server and wiring tools by hand. Users select either …
