Today we're shipping Nemotron 3 Ultra.
A 550B MoE frontier-intelligence open model built for long-running agents.
It delivers 5x faster inference and lowers the cost of complex agentic tasks by up to 30% versus other open frontier models.
Another open-weight release from @thinkymachines 👀 Inkling-Small is here.
With native reasoning over audio and images and variable thinking effort, it's a great choice for fine-tuning, with NVIDIA NeMo on NVIDIA DGX Station.

Today we’re open-sourcing Numbat, an agent-detection and response layer that is designed to work across agent harnesses.
Numbat gives security teams visibility into agent activity, with controls to block selected actions before execution.
