Stand up Nemotron 3 Super 120B-A12B
on Oracle Cloud.

Fits one high-memory node, but needs tensor/expert parallel configuration. Bare-metal GPU shapes and OCI-native imported-model or Kubernetes deployments.

Multi-GPU: Fits one high-memory node, but needs tensor/expert parallel configuration.

Oracle Cloud setup, in the order that matters

OCI Generative AI imported models when supported; OKE vLLM otherwise. Use the provider console for infrastructure and the pinned runtime block for the model server.

  1. 01

    Choose imported model or OKE

    Use OKE with the vLLM Production Stack because this exact family is not in Oracle's explicitly tested imported-model list.

  2. 02

    Prepare model access and capacity

    Use Hugging Face or OCI Object Storage for nvidia/NVIDIA-Nemotron-3-Super-120B-A12B-FP8, reserve OCI GPU shape with at least 2x H100/A100 80GB-class accelerators, and allocate at least 200GB for weights and engine overhead.

  3. 03

    Configure the engine

    Let Open Model Engine select vLLM/SGLang for a compatible import, or apply the runtime block below in OKE with an initial 262,144-token limit.

  4. 04

    Test and clean up

    Verify the chat endpoint, inspect GPU memory and logs, then delete unused endpoints, node pools, and boot volumes to stop charges.

This is a reproducible starting block. Cluster paths still need the model author's distributed recipe and the provider's orchestration layer.

Run this only after logs show the model loaded. A successful HTTP response is not a latency or quality benchmark.

Quota, license, and storage

  • Confirm OCI GPU shape with at least 2x H100/A100 80GB-class accelerators is actually available in the selected region.
  • Read the NVIDIA Nemotron Open Model License terms and accept any gated-model conditions.
  • Budget at least 200GB for weights, cache, and container layers.
  • Keep HF_TOKEN in the provider secret store—not in scripts or templates.

Memory, format, and shutdown

  • Record idle/free VRAM after the model loads and after a representative prompt.
  • Validate the official chat template, reasoning parser, and tool-call parser.
  • Add authentication and TLS in front of port 8000.
  • Verify the provider's stop/delete action actually ends compute billing.

Hand this runbook to Claude Code or Codex

Open a terminal in the repository where you want the deployment files, start claude or codex, then paste this prompt. It asks the agent to verify sources and stop before it creates billable infrastructure.

Deployment prompt
Deploy Nemotron 3 Super 120B-A12B (nvidia/NVIDIA-Nemotron-3-Super-120B-A12B-FP8) on Oracle Cloud. Use this guide as the starting context: https://www.getflops.ai/models/nemotron-3-super-120b-a12b/oracle. Use a planning floor of 2x 80GB GPUs, 200GB storage, vllm v0.18.1, and an initial context limit of 262144 tokens. Open every linked primary source and flag any mismatch instead of guessing. Create a deployment folder containing README.md, .env.example with no secrets, a pinned start script or infrastructure manifest, and smoke-test.sh. Make the endpoint OpenAI-compatible where the runtime supports it. Run local/static validation, estimate the billable resources, and stop before provisioning paid infrastructure until I approve.

The two sources to check first

Checked 2026-07-27. This page separates sourced facts from the planning baseline; verify current runtime support and capacity before spending.
