Mac Version of Perplexity Computer Adds On-Device Mode
Perplexity Computer for Mac has introduced an on-device mode allowing AI models and agents to run locally without an internet connection. The feature is available to Pro, Max, and Enterprise subscribers, offering Qwen 3.6 and PPLX Pro models. This update significantly enhances user privacy and offline capabilities by processing tasks locally and interacting with native apps, though it sets a high barrier with hardware requirements. It showcases the growing trend of bringing complex AI agents directly onto consumer hardware. The on-device mode requires Apple Silicon and a minimum of 36GB of unified memory to function. Upon authorization, the AI can access local files and integrate with applications like Notes, Messages, Mail, and Numbers.
## BACKGROUND
Unified memory in Apple Silicon architecture integrates CPU, GPU, and other components into a single pool of high-bandwidth memory, allowing large AI models to load and run efficiently without traditional discrete VRAM limitations. Qwen is a family of open-weights language models developed by Alibaba Cloud, known for powerful agentic capabilities.
