How to stream in langgraph

[Pratham271]

I want to stream text in langgraph from the agent and by streaming I want to get the output character by character and I tried to do it by .stream method and .astream method and even passed the stream true settings to the open ai configuration but still it is sending the data as a complete chunk

@Pratham271 most LLM providers do not support streaming character by character -- rather they stream token by token. see this conceptual guide for more on high level streaming concepts https://python.langchain.com/docs/concepts/streaming/

to stream tokens in LangGraph, please follow this how-to guide: https://langchain-ai.github.io/langgraph/how-tos/streaming-tokens/#streaming-llm-tokens
