       If you are using a version of <code>@langchain/core</code> < 0.2.3, when calling chat models or LLMs you need to call <code>await model.stream()</code> within your nodes to get token-by-token streaming events, and aggregate final outputs if needed to update the graph state. In later versions of <code>@langchain/core</code>, this occurs automatically, and you can call <code>await model.invoke()</code>.

         Token streaming is supported by many, but not all chat models. Check to see if your LLM integration supports token streaming <a href="https://js.langchain.com/v0.2/docs/integrations/chat/">here (doc)</a>. Note that some integrations may support <i>general</i> token streaming but lack support for streaming tool calls.

         In this how-to, we will create our agent from scratch to be transparent (but verbose). You can accomplish similar functionality using the <code>createReactAgent({ llm, tools })</code> (<a href="/langgraphjs/reference/functions/langgraph_prebuilt.createReactAgent.html">API doc</a>) constructor. This may be more appropriate if you are used to LangChain's <a href="https://js.langchain.com/v0.2/docs/how_to/agent_executor">AgentExecutor</a> class.
