The cheapest way to run Nemotron 3 Ultra

On an illustrative 70M-input / 30M-output monthly workload, today's lowest listed cost is roughly $150/month, at OpenRouter. Input-heavy, output-heavy and cache-heavy workloads can produce different winners. Use the live mix calculator below rather than combining floors from two different providers. On output-token cost alone, a busy self-hosted deployment can work out cheaper (~$1.51/1M output on 4× MI300X). See the math below.

Cache read uses the listed cache rate where available; otherwise it falls back to normal input price. Batch, write-cache, volume and negotiated discounts are excluded.

Or run it yourself: Nemotron 3 Ultra self-hosting economics

Nemotron 3 Ultra is open-weight (OpenMDW-1.1), so the API price above competes with the GPU-hour market. 550B total parameters (MoE, ~55B active per token) needs roughly 757 GB VRAM at FP8 or 379 GB at INT4, KV-cache headroom included.

No single GPU fits Nemotron 3 Ultra at FP8 (757 GB needed), so it needs a multi-GPU node. Cheapest tracked option: 4× MI300X (192 GB each) at roughly $2.00/hr total (RunPod). Rent 4× MI300X at RunPod → INT4 quantization drops the requirement to 379 GB. Tune it in the calculator.

Breakeven estimate: a well-batched vLLM deployment on 4× MI300X ($2.00/hr) at ~736 aggregate tok/s and 50% utilization works out to roughly $1.51 per 1M output tokens, versus $3.60 via the cheapest output-token API (OpenRouter). Self-hosting wins on cost if you can keep the GPU busy. Planning estimate: throughput varies with hardware, quantization, batch size and context. Tune it in the calculator.
