createLangSmithProviderOptions

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.
