Wraps LangSmith config in a way that matches AI SDK provider types.

import { createLangSmithProviderOptions } from "langsmith/experimental/vercel";
import * as ai from "ai";

const lsConfig = createLangSmithProviderOptions<typeof ai.generateText>({
  // Will have appropriate typing
  processInputs: (inputs) => {
    const { messages } = inputs;
    return {
      messages: messages?.map((message) => ({
        ...message,
        content: "REDACTED",
      })),
      prompt: "REDACTED",
    };
  },
});

Note: AI SDK expects only JSON values in an object for provider options, but LangSmith's config may contain non-JSON values. These are not passed to the underlying AI SDK model, so it is safe to cast the typing here.

Creates a LangSmith Telemetry for the Vercel AI SDK.

This adapter implements the Vercel AI SDK's Telemetry interface and maps lifecycle events to LangSmith traces. It creates a root span for the entire generation, child LLM spans for each step, and tool spans for tool calls.

import { generateText, registerTelemetry } from "ai";
import { LangSmithTelemetry } from "langsmith/experimental/vercel";

registerTelemetry(LangSmithTelemetry());

const result = await generateText({
  model: openai("gpt-4o"),
  prompt: "Hello!",
});

Only available in Vercel AI SDK 7.

Wraps Vercel AI SDK 6 or AI SDK 5 functions with LangSmith tracing capabilities.
