Perplexity releases Decider for Mac to run pplx-decider-flash-v1.2 locally
Perplexity has made its 4 billion‑parameter decision model, pplx‑decider‑flash‑v1.2, runnable on a Mac without sending any data off‑device. The free Decider for Mac app installs a local server that mirrors the hosted Decisions API at http://127.0.0.1:8080/v1/decisions, accepting the same JSON payloads for text or image classification. It works on Apple‑silicon Macs (M1 or later) running macOS 13…
Key points
- Decider for Mac runs Perplexity’s 4 B‑parameter pplx‑decider‑flash‑v1.2 model locally on Apple‑silicon Macs.
- The app needs macOS 13+, 16 GB RAM and about 6 GB free disk space, and it incurs no API key or usage fees.
- It supports both text and image classification via the same JSON request format as Perplexity’s hosted Decisions API.
The menu bar interface shows “Ready” once the model is loaded, after which users can run one‑question requests from the terminal or integrate the local endpoint into existing code. Example scripts show how to label a folder of support emails, block commits that contain secrets, and sort screenshots by content, all while keeping the files on the local machine. When higher throughput or the larger pplx‑decider‑v1.2 model is needed, developers can switch the URL and add an Authorization header to call the hosted Perplexity API.
You can now run the Perplexity Decision Model fully locally on your Mac, without any data leaving your machine. Run pplx-decider-flash-v1.2 on your Mac from the menu bar
