NVIDIA ships Nemotron-3.5-Bolt-E4B, a 4GB Gemma-4-derived SLM for low-latency on-device voice assistants

NVIDIA released Nemotron-3.5-Bolt-E4B (4GB) on Hugging Face, post-trained from Gemma-4-E4B-it. It keeps Gemma's conversational strength while improving multi-turn tool use, instruction following, and input grounding, targeting low-memory, low-TTFT use cases like local voice/device assistants, interactive personas, and embedded edge interfaces.

A companion DFlash drafter for speculative decoding, a BF16 full-precision version, and community GGUF quants (ggml-org, unsloth) are available. Licensed for commercial and non-commercial use.
