What is Portable Computer by Perplexity?

The Portable Computer presents a local-first solution as an alternative to the Perplexity Computer, functioning entirely on your personal device to safeguard sensitive information while supporting complex workflows. In partnership with NVIDIA, it adeptly oversees a range of operations, including the orchestrator, planner, tool router, scheduler, durable task queue, local search index, and AI models, all executed on the device itself. This capability allows for data analysis, file synthesis, document and code searching, and task execution directly on the device, facilitating long-running processes without reliance on cloud connectivity. Designed to run on NVIDIA DGX Spark, it employs either Qwen 3.8 27B or PPLX 27B models, and incorporates NVIDIA Nemotron 3.5 Lightning to optimize model selection and performance. The system is fine-tuned to maximize local operations, only escalating tasks that necessitate real-time data, internet access, integration with other applications, or enhanced reasoning abilities. Furthermore, when there is a requirement to send any data to a cloud service, the Portable Computer prioritizes user consent before proceeding, reinforcing user authority over their information sharing. This careful strategy not only prioritizes privacy but also builds user trust in the secure management of their data while allowing seamless integration of various functionalities. As a result, users can confidently leverage advanced computational capabilities without sacrificing their personal privacy.

What is Nemotron 3 Ultra?

The Nemotron 3 Nano, a compact yet robust language model from NVIDIA's Nemotron 3 lineup, is specifically designed to excel in agentic reasoning, engaging dialogue, and programming tasks. Its cutting-edge Mixture-of-Experts Mamba-Transformer architecture selectively activates a specific subset of parameters for each token, allowing for quick inference times while maintaining high accuracy and reasoning skills. With an impressive total of around 31.6 billion parameters, including about 3.2 billion active ones (or 3.6 billion when including embeddings), this model outperforms its predecessor, the Nemotron 2 Nano, while demanding less computational power for every forward pass. It boasts the capability to handle long-context processing of up to one million tokens, enabling it to efficiently analyze lengthy documents, navigate complex workflows, and carry out detailed reasoning tasks in one go. Additionally, it is designed for high-throughput, real-time performance, making it particularly skilled in managing multi-turn dialogues, executing tool invocations, and handling agent-driven workflows that require sophisticated planning and reasoning. This adaptability renders the Nemotron 3 Nano a top-tier option for a wide range of applications that necessitate advanced cognitive functions and seamless interaction. Its ability to integrate these features sets a new standard in the landscape of language models.
