Perplexity has introduced 'Portable Computer,' a new local version of their AI agent that runs entirely on local hardware, offering enhanced data privacy compared to its cloud-based predecessor. Initially exclusive to Nvidia's DGX Spark, the agent aims to execute long-horizon tasks autonomously without consuming cloud credits. Perplexity plans to extend support to desktop Nvidia RTX GPUs soon, utilizing models like Quant 3.8.27B.
