OpenInference Vercel

npm version

This package provides a set of utilities to ingest Vercel AI SDK(>= 3.3) spans into platforms like Arize and Phoenix.

Note: This package requires you to be using the Vercel AI SDK version 3.3 or higher.

Installation

npm install --save @arizeai/openinference-vercel

You will also need to install OpenTelemetry and Vercel packages to your project.

npm i @opentelemetry/api @vercel/otel @opentelemetry/exporter-trace-otlp-proto @arizeai/openinference-semantic-conventions

Usage

@arizeai/openinference-vercel provides a set of utilities to help you ingest Vercel AI SDK spans into platforms and works in conjunction with Vercel's OpenTelemetry support. To get started, you will need to add OpenTelemetry support to your Vercel project according to their guide

To process your Vercel AI SDK Spans add a OpenInferenceSimpleSpanProcessor or OpenInferenceBatchSpanProcessor to your OpenTelemetry configuration.

[!NOTE] The OpenInferenceSpanProcessor does not handle the exporting of spans so you will pass it an exporter as a parameter.

import { registerOTel } from "@vercel/otel";
import { diag, DiagConsoleLogger, DiagLogLevel } from "@opentelemetry/api";
import {
  isOpenInferenceSpan,
  OpenInferenceSimpleSpanProcessor,
} from "@arizeai/openinference-vercel";
import { OTLPTraceExporter } from "@opentelemetry/exporter-trace-otlp-proto";
import { SEMRESATTRS_PROJECT_NAME } from "@arizeai/openinference-semantic-conventions";

// For troubleshooting, set the log level to DiagLogLevel.DEBUG
diag.setLogger(new DiagConsoleLogger(), DiagLogLevel.DEBUG);

export function register() {
  registerOTel({
    serviceName: "phoenix-next-app",
    attributes: {
      // This is not required but it will ensure your traces get added to a specific project in Arize Phoenix
      [SEMRESATTRS_PROJECT_NAME]: "your-next-app",
    },
    spanProcessors: [
      new OpenInferenceSimpleSpanProcessor({
        exporter: new OTLPTraceExporter({
          headers: {
            // API key if you are sending it to Phoenix
            api_key: process.env["PHOENIX_API_KEY"],
          },
          url:
            process.env["PHOENIX_COLLECTOR_ENDPOINT"] ||
            "https://app.phoenix.arize.com/v1/traces",
        }),
        spanFilter: (span) => {
          // Only export spans that are OpenInference to negate non-generative spans
          // This should be removed if you want to export all spans
          return isOpenInferenceSpan(span);
        },
      }),
    ],
  });
}

Now enable telemetry in your AI SDK calls by setting the experimental_telemetry parameter to true.

const result = await generateText({
  model: openai("gpt-4-turbo"),
  prompt: "Write a short story about a cat.",
  experimental_telemetry: { isEnabled: true },
});

For details on Vercel AI SDK telemetry see the Vercel AI SDK Telemetry documentation.
