NVIDIA releases Nemotron 3.5 Bolt E4B, a small open model for local use
Overview
NVIDIA has released Nemotron 3.5 Bolt E4B 4GB, a small open model for local assistants, interactive characters and robots that converse and use tools.
NVIDIA says the model and NVIDIA Cosmos run locally on a Jetson Orin Nano 8GB, as shown in a demo of the Reachy Mini robot.
The model is available on Hugging Face, Ollama, LM Studio, Unsloth and Jetson AI Lab, and also ships as an NVIDIA NIM and through the In-Game Inferencing SDK, according to MarkTechPost. Ollama describes it as a vision-language model with a 128K-token context window. Unsloth says it runs on 6GB RAM and has published GGUF files. Merve Noyan says the E4B version, an 8B model with 4B effective parameters, outperforms Gemma-4 and Qwen3.5 and includes a DFlash drafter for faster decoding.
MarkTechPost reports NVIDIA's tests show the Q4_K_M build using 3.1 to 4.3 GB VRAM on RTX GPUs, and top scores on 15 of 21 benchmarks against Gemma 4 E4B, Qwen3.5-4B and Nemotron 3 Nano 4B. The same article says it trails Qwen3.5-4B on Tau2-Bench, 55.1 to 75.1, and that the GGUF file is 6.18 GB.
