Message
A Message is a piece of information that is sent from the user to an assistant and vice versa. Coupled with life cycle hooks, they are the building blocks of a chat.
A message has a content, a timestamp and cannot be nested.
Example: Reply to a user message
Lets create a simple assistant that replies to a user message with a greeting.

Chat Context
Since LLMs are stateless, you will often have to accumulate the messages of the current conversation in a list to provide the full context to LLM with each query.
You could do that manually with the user_session. However, Chainlit provides a built-in way to do this:
Every message sent or received will be automatically accumulated in cl.chat_context
.
You can then use cl.chat_context.to_openai()
to get the conversation in the OpenAI format and feed it to the LLM.
