Nscale (EU Sovereign)

Portkey provides a robust and secure gateway to facilitate the integration of various Large Language Models (LLMs) into your applications, including the models hosted on Nscale.

Provider Slug. nscale

Portkey SDK Integration with Nscale

Portkey provides a consistent API to interact with models from various providers. To integrate Nscale with Portkey:

1. Install the Portkey SDK

NodeJS

npm install --save portkey-ai

npm install --save portkey-ai

pip install portkey-ai

2. Initialize Portkey with the Virtual Key

To use Nscale with Virtual Key, get your API key from here. Then add it to Portkey to create the virtual key.

NodeJS SDK

import Portkey from 'portkey-ai'

const portkey = new Portkey({
  apiKey: "PORTKEY_API_KEY", // defaults to process.env["PORTKEY_API_KEY"]
  virtualKey: "VIRTUAL_KEY" // Your Nscale Virtual Key
})

import Portkey from 'portkey-ai'

const portkey = new Portkey({
  apiKey: "PORTKEY_API_KEY", // defaults to process.env["PORTKEY_API_KEY"]
  virtualKey: "VIRTUAL_KEY" // Your Nscale Virtual Key
})

from portkey_ai import Portkey

portkey = Portkey(
  api_key="PORTKEY_API_KEY",  # Replace with your Portkey API key
  virtual_key="NSCALE_VIRTUAL_KEY"
)

3. Invoke Chat Completions

NodeJS SDK

const chatCompletion = await portkey.chat.completions.create({
  messages: [{ role: 'user', content: 'Say this is a test' }],
  model: 'meta-llama/Llama-4-Scout-17B-16E-Instruct',
});

console.log(chatCompletion.choices);

const chatCompletion = await portkey.chat.completions.create({
  messages: [{ role: 'user', content: 'Say this is a test' }],
  model: 'meta-llama/Llama-4-Scout-17B-16E-Instruct',
});

console.log(chatCompletion.choices);

completion = portkey.chat.completions.create(
  messages= [{ "role": 'user', "content": 'Say this is a test' }],
  model= 'meta-llama/Llama-4-Scout-17B-16E-Instruct'
)

print(completion)

4. Invoke Image Generation

NodeJS SDK

const response = await portkey.images.generations.create({
  prompt: "A beautiful sunset over mountains",
  model: "stabilityai/stable-diffusion-xl-base-1.0",
  n: 1,
  size: "1024x1024"
});

console.log(response.data[0].url);

const response = await portkey.images.generations.create({
  prompt: "A beautiful sunset over mountains",
  model: "stabilityai/stable-diffusion-xl-base-1.0",
  n: 1,
  size: "1024x1024"
});

console.log(response.data[0].url);

response = portkey.images.generate(
  prompt="A beautiful sunset over mountains",
  model="stabilityai/stable-diffusion-xl-base-1.0",
  n=1,
  size="1024x1024"
)

print(response.data[0].url)
