NVIDIA Nemotron 3.5 Bolt E4B 4GB (post-trained Gemma 4 E4B)

Bolt E4B builds on Gemma 4 E4B with Nemotron post-training. It combines natural conversation with multi-turn agentic capabilities to power voice/device assistants, interactive characters and robotic/IoT interfaces running on NVIDIA GeForce RTX, Jetson, RTX Spark and DGX Spark. Bolt E4B offers ~40% higher average quality against our prior model on key conversational agent benchmarks and outputs up to ~80% fewer tokens vs peers.
