4x Faster Throughput

### Lightning-Speed Inference

Activates only 3.5B parameters per token, delivering 4x faster throughput than Nemotron 2 Nano.

1M Token Context

### Ultra-Long Context Window

Process documents, code repositories, and conversations up to 1 million tokens without degradation.

Hybrid MoE Architecture

### Efficient Expert Routing

Mixture-of-Experts with Mamba-2 layers reduces compute cost while maintaining reasoning accuracy.
