Perplexity launches a local AI agent with zero token costs

Months after launching its agentic AI tool, “Personal Computer,” Perplexity is introducing a new option for users who prefer to run their AI agents locally.

The company today announced “Portable Computer,” its local-first agent, in partnership with NVIDIA. Portable Computer will run entirely on-device. The agent, along with the models and other tools, lives locally on the user’s device. This ensures that user data isn’t sent to the cloud and offers a higher level of privacy for sensitive data.

Portable Computer will use very small models such as Qwen 3.8 and NVIDIA Nemotron 3.5 Lightning. According to Perplexity, these models can perform complex agentic tasks and run on local hardware, making them a good choice for its new local agentic AI.

However, Portable Computer still supports functions such as web search and advanced reasoning with cutting-edge models. If any such feature is required for the task at hand, Perplexity says the agent will always ask the user for permission before proceeding.

The company also states that work handled locally by the user’s machine will not incur any token costs. That could make a huge difference for users who need to carry out high-volume tasks without worrying about exhausting their tokens or incurring extra costs.

Perplexity’s Portable Computer currently supports NVIDIA’s DGX Spark platform and can run Qwen 3.8 or PPLX 27B — a post-trained version of the Qwen 3.8 model. The company also says that support for the NVIDIA Nemotron 3.5 Lightning model, as well as NVIDIA RTX GPUs, is coming soon. Users subscribed to Perplexity Pro or Max can set up Portable Computer on their NVIDIA DGX Spark systems starting today.
