NVIDIA AI Model Center
A Python skill that provides a unified interface to 42+ NVIDIA NIM API models — LLM chat, vision analysis, text embeddings, image generation, and more.
Quick Start
from model_center import ModelCenter
center = ModelCenter()
# List all models
models = center.list_models()
print("Available categories:", list(models.keys()))
# Get model info
info = center.get_model_info('nemotron-3-super-8b')
print(f"Model: {info['name']}, Provider: {info['provider']}")
# Compare pricing
comparisons = center.compare_pricing(['nemotron-3-super-8b', 'llama-3.1-70b-instruct'])
for c in comparisons:
print(f"{c['name']}: ${c['input_price']}/M in, ${c['output_price']}/M out")
# Get recommendations
rec = center.recommend_model('code generation', 'low', False)
print(f"Recommended: {rec}")
# Estimate cost
cost = center.estimate_cost('nemotron-3-super-8b', 1000, 500)
print(f"Estimated cost: ${cost['total_cost']}")
# Chat with a model (requires NVIDIA_API_KEY env var)
# response = center.chat_completion(
# model='nemotron-3-super-8b',
# messages=[{'role': 'user', 'content': 'Hello'}],
# temperature=0.7,
# max_tokens=100
# )
Setup
- Get an API key from build.nvidia.com
- Set the
NVIDIA_API_KEYenvironment variable:$env:NVIDIA_API_KEY = "nvapi-..." - Install dependency:
