  "account": "Perplexity and Nvidia have joined forces to launch Portable Computer, an agentic AI platform designed for local use on PCs and workstations. This optimized version of Perplexity's Computer AI platform allows users to run complex AI tasks without relying on cloud services, thereby avoiding high token costs. Nate Kupp, from Perplexity, announced that Portable Computer retains the same user interface as its predecessor and includes all necessary features for local inference. However, it may still require user consent to send data to the cloud for particularly complex tasks.\n\nNvidia's Director of Developer Technologies, Nader Khalil, highlighted that local AI has reached a critical point, transitioning from a niche interest for power users to a crucial productivity tool for everyday consumers. Portable Computer comprises an agent, an orchestrator, and two local models - Qwen 3.8 and PPLX, with the latter capable of scaling up to 27 billion parameters. The app also plans to support Nemotron 3.5 Lightning, an Nvidia-developed 30-billion-parameter Mixture-of-Experts (MoE) model, boasting 3 billion active parameters per token.\n\nBenchmarks from Perplexity demonstrate Portable Computer's efficiency. When using the Qwen 3.8 27B model on a DGX Spark workstation, the platform achieved an impressive accuracy score of 82.6% while utilizing 520,000 tokens. This surpassed Pi's 77.6% accuracy with 77.6% on 53 tasks, including deep research, financial analysis, and document creation. On PPLX 27B, Portable Computer scored 85.4%, using 678,000 tokens.\n\nPortable Computer outperformed Hermes, another AI platform, in BrowseComp (66.7% vs 43.9%) and ParseBench-100 (65.1% vs 34.6%) benchmarks. It also used the least tokens across all three benchmarks, indicating higher efficiency. Portable Computer is currently available to Pro, Max, and Enterprise subscribers on Nvidia's DGX Spark, a Linux small AI desktop featuring the Grace Blackwell GB10 chip, paired with a 20-core CPU, a Blackwell GPU, and 128GB of unified memory. It's also accessible on Linux PCs with Nvidia RTX GPUs of at least 24GB VRAM, with Windows support expected in September.",

He added that some complex tasks may still require access to more powerful frontier models hosted online, but the app... Read Entire Article",
