Nvidia says Nemotron 3.5 Bolt E4B 4GB is now available to developers through its In-Game Inferencing SDK, enabling AI character conversations and tool use locally on GeForce RTX and RTX Spark systems.

The model supports a 64k context window and 35 languages. It can call application APIs across multiple conversation turns and use game state to guide responses. A conversational mode encourages concise responses suited to speech.

Developers can enable reasoning for complex requests, disable it for faster responses, or cap thinking to meet latency targets. Those controls let game developers adjust how much processing character interactions receive.
