Build

Build structured, model independent LLM calls

Interact with frontier, open-source, and multimodal models using a unified, structured syntax. We empower you to instruct models as code, and reduce the need for complex prompts.

import Client from "opperai";

const client = new Client();

(async () => {
    // remember to return the json_payload from the call
    const {json_payload} = await client.call({
        name: "extractRoom",
        input: "Room at Grand Hotel with 2 beds and a view to the sea.",
        output_schema: {
            $schema: "https://json-schema.org/draft/2020-12/schema",
            type: "object",
            properties: {
                beds: {
                    description: "The number beds",
                    type: "number",
                },
                seaview: {
                    description: "The room has a seaview",
                    type: "boolean",
                },
                description: {
                    description: "The description of the room",
                    type: "string",
                },
            },
            required: ["beds", "seaview", "description"],
        },
    });

})();

Integrate

Integrate your own data and knowledge

Opper enables both indexing and retrieval of the semantically relevant parts of data and connect it to calls, while you retain full integration control.

See Sample app
import Client from "opperai";

const client = new Client();

async function main() {
    try {
        const index = await client.indexes.create("my_index");

        await index.add([
            {
                key: "doc1",
                content: "Opper is a comprehensive platform for building and deploying AI-powered applications.",
                metadata: { type: "overview" }
            }
        ]);

        const knowledge = await index.query({
            query: "What is Opper?",
            k: 1 
        });

        console.log(knowledge);
        // [{ content: 'Opper is a comprehensive platform for building and deploying AI-powered applications.', metadata: { type: 'overview' } }]

    } catch (error) {
        console.error("An error occurred:", error);
    }
}

main();
