About

Nemotron 3 Nano is a compact, open large language model in NVIDIA’s Nemotron 3 family, designed for efficient agentic reasoning, conversational AI, and coding tasks. It uses a hybrid Mixture-of-Experts Mamba-Transformer architecture that activates only a small subset of parameters per token, enabling low-latency inference while maintaining strong accuracy and reasoning performance. It has approximately 31.6 billion total parameters with around 3.2 billion active (3.6 billion including embeddings), allowing it to achieve higher accuracy than previous Nemotron 2 Nano while using less computation per forward pass. Nemotron 3 Nano supports long-context processing of up to one million tokens, enabling it to handle large documents, multi-step workflows, and extended reasoning chains in a single pass. It is designed for high-throughput, real-time execution, excelling in multi-turn conversations, tool calling, and agent-based workflows where tasks require planning, reasoning, and more.

About

Portable Computer is a local-first version of Perplexity Computer that runs entirely on your own machine, keeping private data on-device while still supporting complex agentic workflows. Built with NVIDIA, it runs the orchestrator, planner, tool router, scheduler, durable task queue, local search index, and AI models locally, so it can analyze data, synthesize files, search documents and code, take actions on the device, and keep long-running jobs active without relying on the cloud. It runs on NVIDIA DGX Spark with Qwen 3.8 27B or PPLX 27B, with NVIDIA Nemotron 3.5 Lightning coming to the model picker. It is trained to complete as much of each task locally as possible and can escalate only the steps that need current information, browser access, connected apps, or frontier reasoning. When a task needs to send content from the device to a cloud service, Portable Computer asks for permission before proceeding.
