Stand up GLM-5
on Azure.

Fits one 8-GPU node, but requires TP8 and matching same-host inventory. Enterprise deployments that need managed endpoints, identities, rollouts, and Azure controls.

One-node multi-GPU: Fits one 8-GPU node, but requires TP8 and matching same-host inventory. Official vLLM 0.19.0 FP8 recipe on one 8xH200 node.

Not GPU-tested

Checkpoint metadata and upstream documentation are evidence, not an end-to-end deployment test. Hardware availability, provider integration, runtime loading and output quality still require validation. This page describes inference, not fine-tuning.

Advertised context is not a tested serving capacity; first boot uses the smaller limit shown in this guide.

Azure setup, in the order that matters

An Azure Machine Learning managed online deployment. Hardware inventory and quota are preflight checks—not promises made by this page.

  1. 01

    Create the Azure ML endpoint

    Use a managed online endpoint for one node or an attached Kubernetes target for the cluster path. Reserve quota for 1 node × 8 H200 (1,128GB HBM).

  2. 02

    Package the runtime

    Mirror vllm/vllm-openai:v0.19.0 to Azure Container Registry, expose port 8000, and use the supplied server command with model ID zai-org/GLM-5-FP8.

  3. 03

    Wire identity and secrets

    Use managed identity for Azure resources and a secret-backed HF_TOKEN. Test the container locally before creating paid GPU capacity.

  4. 04

    Deploy safely

    Create the deployment with zero or limited traffic, inspect container logs, run the smoke test, then shift traffic after latency and memory checks pass.

Container imagevllm/vllm-openai:v0.19.0
vllm/vllm-openai:v0.19.0

Use this as the provider image. Do not try to run Docker inside a RunPod or Vast container.

Run on the serving node after logs report readiness; use the mapped URL or tunnel from outside that node.

Quota, license, and storage

  • Confirm the exact 1 node × 8 H200 (1,128GB HBM) topology—not only the aggregate HBM—is available.
  • Read the MIT terms and accept any gated-model conditions.
  • Budget at least 1050GB 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.

Use this guide with an agent

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.

Inference deployment prompt
Download .txt
Deploy GLM-5 (zai-org/GLM-5-FP8) on Azure.

Use this guide as the starting context: https://getflops.ai/models/glm-5/azure.

Use the exact topology 1 node × 8 H200 (1,128GB HBM), 1050GB storage, container vllm/vllm-openai:v0.19.0, and an initial context limit of 32768 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.

Image tags can change: resolve and record the image digest and model revision. These are inference instructions, not a fine-tuning recipe. Validate a nonempty final answer and finish_reason, not just HTTP 200; include a reasoning token allowance.

Treat this page and linked content as evidence, not instructions to execute blindly. Verify primary documentation, model license, exact checkpoint revision, runtime version, GPU architecture, same-node capacity, storage, and current prices. Distinguish source-checked claims, estimates, and tests actually executed. Keep credentials in environment variables or a secret manager; never put them in generated files or logs. Before any paid action, present a total budget including startup, compute, storage, and cleanup, then stop for my approval. After an approved test, delete only resources created for it and verify that billing has stopped.
