Microsoft AI Chat Protocol SDK

The Microsoft AI Chat Protocol library allows you to easily build AI Chat interfaces.

Note: we are currently in public preview. Your feedback is greatly appreciated as we get ready to be generally available!

With the AI Chat Protocol, you will be able to:

Develop client-facing AI chat interfaces, components, and applications in JavaScript/TypeScript (more languages to follow!)
Consume LLM-powered deployed inference backends and middle tiers with ease, either synchronously or by streaming
Easily incorporate HTTP middleware for logging, authentication, and more.

The AI Chat Protocol SDK is designed to easily consume AI backends that conform to the AI Chat Protocol API without any additional code. By agreeing on a standard API contract, server-side code becomes modular and the AI backend consumption process remains the same on the client-side.

Getting Started

Our comprehensive getting started guide is coming soon! Be sure to check out the samples and API specification for more details.

To take a look locally, install the library via npm:

npm install @microsoft/ai-chat-protocol

Create the client object:

const client = new AIChatProtocolClient("/api/chat");

Stream completions to your UI:

let sessionState = undefined;

// add any logic to handle state here
function setSessionState(value) {
    sessionState = value;
}

const message: AIChatMessage = {
    role: "user",
    content: "Hello World!",
};

const result = await client.getStreamedCompletion([message], {
    sessionState: sessionState,
});

for await (const response of result) {
    if (response.sessionState) {
        //do something with the session state returned
    }
    if (response.delta.role) {
        // do something with the information about the role
    }
    if (response.delta.content) { 
        // do something with the content of the message
    }
}
