Run Nemotron 3 Nano 4B · Q8_0 on your own GPU

Nemotron 3 Nano 4B · Q8_0 is a small & fast catalog model (4.0B) managed with Ollama. Catalog memory is estimated at 6.5 GB with Q8_0 for a short context (4–8K tokens). Validate output quality and memory use with your workload on your hardware.

Deploy the catalog Ollama tag on your machine and verify the pulled model's quantization. Once deployed, gpuos serves it as nemotron-3-nano-4b-q8-0 through the hosted gpuos gateway, with API keys, optional token quotas and usage metering. Request and response payloads pass through that gateway.

Compare GPU memory for Nemotron 3 Nano 4B · Q8_0

Catalog estimate at Q8_0, not a measured benchmark. Chat estimates assume a short context; embedding memory depends on input and batch size. The comparison includes a 5% screening margin; it does not establish runtime performance. More in how much VRAM an LLM needs.
