What it takes to serve Nemotron-3-Nano-Omni-30B-A3B-Reasoning-NVFP4 (18.3B parameters): the memory its weights need at each precision, and the cheapest way to rent enough data-center GPUs to hold them.

Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Sep 18, 2026.

SAVRN's Notes on Nemotron-3-Nano-Omni-30B-A3B-Reasoning-NVFP4

Meeting recordings, training videos, scanned documents and speech all go through one model here, which is the point of an any-to-any release with a 262,144-token window. The 4-bit line, the NVFP4 in the name, needs 9.2 GB of weights and 11 GB of memory on the cheapest listed setup, a single MI300X with 192 GB at $1.85 an hour on demand. At 16-bit the need is 44 GB, so one card still carries it with room for long context.

The license reads other and our facts carry no summary of its terms, so nothing about commercial use or redistribution can be assumed; read the publisher's text in full before this touches production. The checkpoint is quantized from the BF16 Reasoning release, so behavior questions get settled against that parent, and it was trained on Nemotron-Image-Training-v3. Released April 24, 2026, updated August 24, 2026: still moving.

gemma-4-12B-it-FP8-dynamic

Thor Lin

Self-quantized FP8 (dynamic) of google/gemma-4-12B-it — Google's encoder-free omni model (text + image + audio + video). Quantized and benchmarked on an NVIDIA DGX Spark (GB10, sm121a). TL;DR: 13 GB on disk (from 23 GB BF16), 15.9 tok/s on a GB10 via vLLM, all four modalities intact. Data-free — no calibration needed. If you want the smallest + fastest build, see the sibling NVFP4 weight-only repo. FP8 is the conservative choice (dynamic activations, no calibration, widest kernel support). I scored all three formats on MMLU (English, 57 subjects) and TMMLU+ (Traditional Chinese, 66 subjects) with lm-evaluation-harness, 5-shot, chat template applied, limit=30 (N ≈ 1,710 EN / 1,980 TC, ±~1.0…
