Quick Reference

1. Deploy NIM Container with Single Command

# Deploy a Llama 3 inference microservice
docker run --gpus all \
  -e NGC_API_KEY=$NGC_API_KEY \
  -p 8000:8000 \
  nvcr.io/nvidia/nim/llama-3-8b-instruct:latest

Launches a GPU-accelerated Llama 3 inference service on port 8000

2. Call NIM API Endpoint (OpenAI-Compatible)

# Use NIM API like OpenAI
import openai

client = openai.OpenAI(
    base_url="http://localhost:8000/v1",
    api_key="not-used"  # NIM handles auth differently
)

response = client.chat.completions.create(
    model="llama-3-8b-instruct",
    messages=[
        {"role": "user", "content": "Explain quantum computing"}
    ],
    temperature=0.7,
    max_tokens=512
)

print(response.choices[0].message.content)

Standard OpenAI SDK works seamlessly with NIM endpoints

3. Deploy NIM on Kubernetes with Helm

# Add NVIDIA Helm repository
helm repo add nvidia https://helm.ngc.nvidia.com/nvidia

# Deploy NIM microservice
helm install my-nim nvidia/nim \
  --set image.repository=nvcr.io/nvidia/nim/llama-3-8b-instruct \
  --set image.tag=latest \
  --set replicaCount=3 \
  --set resources.limits.nvidia.com/gpu=1

Scale NIM inference across Kubernetes cluster with GPU allocation

4. Access NIM via REST API

# Direct REST API call to NIM
curl -X POST http://localhost:8000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "llama-3-8b-instruct",
    "messages": [{"role": "user", "content": "Hello, world!"}],
    "temperature": 0.5,
    "max_tokens": 100
  }'

REST endpoint for language-agnostic integration

5. Deploy Custom Fine-Tuned Model

# Deploy your custom fine-tuned model with NIM
docker run --gpus all \
  -e NGC_API_KEY=$NGC_API_KEY \
  -e MODEL_PATH=/models/my-custom-model \
  -v /path/to/models:/models \
  -p 8000:8000 \
  nvcr.io/nvidia/nim/base-llm:latest

NIM supports custom models fine-tuned on your data

6. RAG Pipeline with NIM

# Building retrieval-augmented generation with NIM
from langchain.llms import OpenAI
from langchain.chains import RetrievalQA
from langchain.vectorstores import FAISS

# Point LangChain to NIM endpoint
llm = OpenAI(
    base_url="http://localhost:8000/v1",
    api_key="not-used",
    model="llama-3-8b-instruct"
)

# Create RAG chain with NIM-powered LLM
qa_chain = RetrievalQA.from_chain_type(
    llm=llm,
    retriever=vectorstore.as_retriever(),
    chain_type="stuff"
)

answer = qa_chain.run("What are the key features of NIM?")

Integrate NIM into RAG workflows with frameworks like LangChain

7. Configure NIM for Multi-GPU Setup

# docker-compose.yml for multi-GPU NIM deployment
version: '3'
services:
  nim-service:
    image: nvcr.io/nvidia/nim/llama-3-70b-instruct:latest
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 4  # Use 4 GPUs
              capabilities: [gpu]
    environment:
      - NGC_API_KEY=${NGC_API_KEY}
      - TENSOR_PARALLEL_SIZE=4
    ports:
      - "8000:8000"

Leverage multiple GPUs for large model inference

8. Monitor NIM with Observability Metrics

# Access built-in metrics from NIM
import requests

metrics = requests.get("http://localhost:8000/metrics")
print(metrics.text)

# Prometheus-compatible metrics include:
# - nim_inference_requests_total
# - nim_inference_duration_seconds
# - nim_gpu_utilization_percent
# - nim_throughput_tokens_per_second

Built-in Prometheus metrics for dashboarding and monitoring

9. Build AI Agent with NVIDIA Blueprints

# Use NVIDIA AI Blueprints with NIM
from nvidia_blueprints import AgentBlueprint

# Initialize blueprint with NIM endpoint
agent = AgentBlueprint(
    nim_endpoint="http://localhost:8000/v1",
    model="llama-3-8b-instruct",
    tools=["web_search", "calculator", "code_executor"]
)

# Execute agentic workflow
result = agent.run(
    task="Research and summarize recent AI developments"
)

Predefined AI workflows using NIM as inference backend

10. Deploy NIM on Hugging Face Dedicated Endpoints

# Alternative: Use Hugging Face dedicated endpoints
from huggingface_hub import InferenceClient

client = InferenceClient(
    model="nvidia/llama-3-8b-nim",
    token=hf_token
)

response = client.text_generation(
    "Explain NVIDIA NIM",
    max_new_tokens=200
)

Managed NIM deployment via Hugging Face cloud infrastructure

Performance Optimization Tips

Inference Speed

• Use TensorRT-LLM for NVIDIA GPUs (up to 8x faster)
• Enable tensor parallelism for large models (>70B)
• Use quantization (INT8, FP8) for memory efficiency
• Batch requests for higher throughput

Resource Utilization

• Monitor GPU memory with NIM metrics
• Adjust

  max_batch_size

  for your workload
• Use appropriate GPU SKU (H100, A100, L40S, RTX)
• Enable KV cache optimization for repeated queries

Scaling Strategy

• Horizontal scaling with Kubernetes for high QPS
• Vertical scaling (more GPUs) for larger models
• Load balancing across NIM instances
• Auto-scaling based on queue depth and latency

Troubleshooting

Common Issues

Container won't start:

• Verify NGC_API_KEY is set correctly
• Check GPU availability:

  nvidia-smi

• Ensure NVIDIA Container Toolkit is installed

Out of memory errors:

• Reduce model size or use quantized version
• Increase GPU memory or use multi-GPU
• Adjust batch size and context length limits

Slow inference:

• Check GPU utilization in metrics
• Verify using optimized engine (TensorRT-LLM)
• Enable tensor parallelism for large models
• Reduce precision (FP16, INT8)

API compatibility issues:

• Verify OpenAI SDK version compatibility
• Check endpoint URL format (

  /v1/chat/completions

  )
• Review NIM logs for error details
