Portkey’s suite of features - AI gateway, observability, prompt management, and continuous fine-tuning are all enabled for the OSS models (Llama2, Mistral, Zephyr, and more) available on Anyscale endpoints.

​
Portkey SDK Integration with Anyscale

​
1. Install the Portkey SDK

npm install --save portkey-ai

​
2. Initialize Portkey with Anyscale Virtual Key

To use Anyscale with Portkey, get your Anyscale API key from here, then add it to Portkey to create the virtual key. 
import Portkey from 'portkey-ai'

const portkey = new Portkey({
    apiKey: "PORTKEY_API_KEY", // defaults to process.env["PORTKEY_API_KEY"]
    provider:"@ANYSCALE_PROVIDER" // Your Anyscale Virtual Key
})

​
3. Invoke Chat Completions with Anyscale

const chatCompletion = await portkey.chat.completions.create({
    messages: [{ role: 'user', content: 'Say this is a test' }],
    model: 'mistralai/Mistral-7B-Instruct-v0.1',
});

console.log(chatCompletion.choices);

​
Directly Using Portkey’s REST API

Alternatively, you can also directly call Anyscale models through Portkey’s REST API - it works exactly the same as OpenAI API, with 2 differences:
  1. You send your requests to Portkey’s complete Gateway URL https://api.portkey.ai/v1/chat/completions
  2. You have to add Portkey specific headers.
    1. x-portkey-api-key for sending your Portkey API Key
    2. x-portkey-provider for sending your provider’s virtual key (Alternatively, if you are not using Virtual keys, you can send your Auth header for your provider, and pass the x-portkey-provider header along with it)
curl https://api.portkey.ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $ANYSCALE_API_KEY" \
  -H "x-portkey-api-key: $PORTKEY_API_KEY" \
  -H "x-portkey-provider: anyscale" \
  -d '{
    "model": "mistralai/Mistral-7B-Instruct-v0.1",
    "messages": [{"role": "user","content": "Hello!"}]
  }'

​
Using the OpenAI Python or Node SDKs for Anyscale

You can also use the baseURL param in the standard OpenAI SDKs and make calls to Portkey + Anyscale directly from there. Like the Rest API example, you are only required to change the baseURL and add defaultHeaders to your instance. You can use the Portkey SDK to make it simpler: 
import OpenAI from 'openai'; // We're using the v4 SDK
import { PORTKEY_GATEWAY_URL, createHeaders } from 'portkey-ai'

const anyscale = new OpenAI({
  apiKey: 'ANYSCALE_API_KEY',
  baseURL: PORTKEY_GATEWAY_URL,
  defaultHeaders: createHeaders({
    provider: "anyscale",
    apiKey: "PORTKEY_API_KEY" // defaults to process.env["PORTKEY_API_KEY"]
  })
});

async function main() {
  const chatCompletion = await anyscale.chat.completions.create({
    messages: [{ role: 'user', content: 'Say this is a test' }],
    model: 'mistralai/Mistral-7B-Instruct-v0.1',
  });

  console.log(chatCompletion.choices);

}

main();
This request will be automatically logged by Portkey. You can view this in your logs dashboard. Portkey logs the tokens utilized, execution time, and cost for each request. Additionally, you can delve into the details to review the precise request and response data.

​
Managing Anyscale Prompts

You can manage all prompts for Anyscale’s OSS models in the Prompt Library. All the current models of Anyscale are supported.

​
Creating Prompts

Use the Portkey prompt playground to set variables and try out various model params to get the right output.

​
Using Prompts

Deploy the prompts using the Portkey SDK or REST API 
import Portkey from 'portkey-ai'

const portkey = new Portkey({
    apiKey: "PORTKEY_API_KEY", // defaults to process.env["PORTKEY_API_KEY"]
})

// Make the prompt creation call with the variables

const promptCompletion = await portkey.prompts.completions.create({
    promptID: "YOUR_PROMPT_ID",
    variables: {
        //Required variables for prompt
    }
})
We can also override the hyperparameters:
const promptCompletion = await portkey.prompts.completions.create({
    promptID: "YOUR_PROMPT_ID",
    variables: {
        //Required variables for prompt
    },
    max_tokens: 250,
    presence_penalty: 0.2
})
Observe how this streamlines your code readability and simplifies prompt updates via the UI without altering the codebase.

Advanced Use Cases

​
Streaming Responses

Portkey supports streaming responses using Server Sent Events (SSE). 
import OpenAI from 'openai';
import { PORTKEY_GATEWAY_URL, createHeaders } from 'portkey-ai'

const anyscale = new OpenAI({
  baseURL: PORTKEY_GATEWAY_URL,
  defaultHeaders: createHeaders({
    mode: "anyscale",
    apiKey: "PORTKEY_API_KEY" // defaults to process.env["PORTKEY_API_KEY"]
  })
});

async function main() {
  const stream = await anyscale.chat.completions.create({
    model: 'mistralai/Mistral-7B-Instruct-v0.1',
    messages: [{ role: 'user', content: 'Say this is a test' }],
    stream: true,
  });

  for await (const chunk of stream) {
    process.stdout.write(chunk.choices[0]?.delta?.content || '');
  }
}

main();
