title: Quick Start
---

<Info>
  **Prerequisite**: All Agentic packages are [ESM
  only](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c)
  and require `Node.js >= 18` or an equivalent environment (Bun, Deno, CF
  workers, etc).

<Steps>
  <Step title='Install core deps (zod)'>
    <CodeGroup>
      ```bash npm
      npm install zod
      ```

      ```bash yarn
      yarn add zod
      ```

      ```bash pnpm
      pnpm add zod
      ```
    </CodeGroup>

  </Step>

  <Step title='Install AI tools'>
    You can either install all of the AI tools via `@agentic/stdlib`, or you can install them individually via their respective packages (`@agentic/weather`, `@agentic/twitter`, etc.).

    <AccordionGroup>
      <Accordion title="Install all AI tools">
        <CodeGroup>
          ```bash npm
          npm install @agentic/stdlib
          ```

          ```bash yarn
          yarn add @agentic/stdlib
          ```

          ```bash pnpm
          pnpm add @agentic/stdlib
          ```
        </CodeGroup>
      </Accordion>

      <Accordion title="Install individual AI tools">
        Docs for individual tools are available [here](/tools).

        Here's an example of how to install the [Weather tool](/tools/weather):

        <CodeGroup>
          ```bash npm
          npm install @agentic/weather
          ```

          ```bash yarn
          yarn add @agentic/weather
          ```

          ```bash pnpm
          pnpm add @agentic/weather
          ```
        </CodeGroup>
      </Accordion>

    </AccordionGroup>

    <Note>
      There is no functional difference between using `@agentic/stdlib` versus using the individual tool packages directly. The only difference is if you want to optimize your install size (when running on serverless functions, for instance).

      The default examples all use `@agentic/stdlib` for simplicity.
    </Note>

  </Step>

  <Step title='Install an AI SDK Adapter'>
    To use Agentic with one of the supported AI SDKs, you'll also need to install its corresponding adapter package.

    <AccordionGroup>
      <Accordion title="Vercel AI SDK">
        <CodeGroup>
          ```bash npm
          npm install @agentic/ai-sdk ai
          ```

          ```bash yarn
          yarn add @agentic/ai-sdk ai
          ```

          ```bash pnpm
          pnpm add @agentic/ai-sdk ai
          ```
        </CodeGroup>

        See the [AI SDK adapter docs](/sdks/ai-sdk) for usage details.
      </Accordion>

      <Accordion title="LangChain">
        <CodeGroup>
          ```bash npm
          npm install @agentic/langchain @langchain/core langchain
          ```

          ```bash yarn
          yarn add @agentic/langchain @langchain/core langchain
          ```

          ```bash pnpm
          pnpm add @agentic/langchain @langchain/core langchain
          ```
        </CodeGroup>

        See the [LangChain adapter docs](/sdks/langchain) for usage details.
      </Accordion>

      <Accordion title="LlamaIndex">
        <CodeGroup>
          ```bash npm
          npm install @agentic/llamaindex llamaindex
          ```

          ```bash yarn
          yarn add @agentic/llamaindex llamaindex
          ```

          ```bash pnpm
          pnpm add @agentic/llamaindex llamaindex
          ```
        </CodeGroup>

        See the [LlamaIndex adapter docs](/sdks/llamaindex) for usage details.
      </Accordion>

      <Accordion title="Firebase Genkit">
        <CodeGroup>
          ```bash npm
          npm install @agentic/genkit genkit
          ```

          ```bash yarn
          yarn add @agentic/genkit genkit
          ```

          ```bash pnpm
          pnpm add @agentic/genkit genkit
          ```
        </CodeGroup>

        See the [Genkit adapter docs](/sdks/genkit) for usage details.
      </Accordion>

      <Accordion title="Dexa Dexter">
        <CodeGroup>
          ```bash npm
          npm install @agentic/dexter @dexaai/dexter
          ```

          ```bash yarn
          yarn add @agentic/dexter @dexaai/dexter
          ```

          ```bash pnpm
          pnpm add @agentic/dexter @dexaai/dexter
          ```
        </CodeGroup>

        See the [Dexter adapter docs](/sdks/dexter) for usage details.
      </Accordion>

      <Accordion title="OpenAI SDK">
        <CodeGroup>
          ```bash npm
          npm install openai
          ```

          ```bash yarn
          yarn add openai
          ```

          ```bash pnpm
          pnpm add openai
          ```
        </CodeGroup>

        There's no need for a separate adapter with the OpenAI SDK since all agentic tools are compatible with OpenAI by default. You can use `AIFunctionSet.specs` for function calling or `AIFunctionSet.toolSpecs` for parallel tool calling.

        See the [OpenAI adapter docs](/sdks/openai) for usage details.
      </Accordion>

    </AccordionGroup>

    <Note>
      You can use Agentic without any of these AI SDKs. `@agentic/core`, `@agentic/stdlib`, and all individual tool packages are compatible with any LLM and AI SDK that supports function calling / tool use.
    </Note>
