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.

      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="Mastra">
        <CodeGroup>
          ```bash npm
          npm install @agentic/mastra @mastra/core
          ```

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

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

        See the [Mastra adapter docs](/sdks/mastra) 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>
