Function chat 

pub fn chat(model: Model) -> ChatBuilder

Creates a new ChatBuilder with the specified model.

This is a convenience function that returns a ChatBuilder instance initialized with the given model. You can then chain additional methods to configure the chat request before sending it.

Example

use ic_llm::{Model, ChatMessage, Response};

// Basic usage
ic_llm::chat(Model::Llama3_1_8B)
    .with_messages(vec![
        ChatMessage::System {
            content: "You are a helpful assistant".to_string(),
        },
        ChatMessage::User {
            content: "How big is the sun?".to_string(),
        },
    ])
    .send()
    .await

You can also add tools to the chat:

use ic_llm::{Model, ChatMessage, ParameterType, Response};

ic_llm::chat(Model::Llama3_1_8B)
    .with_messages(vec![
        ChatMessage::System {
            content: "You are a helpful assistant".to_string(),
        },
        ChatMessage::User {
            content: "What's the balance of account abc123?".to_string(),
        },
    ])
    .with_tools(vec![
        ic_llm::tool("icp_account_balance")
            .with_description("Lookup the balance of an ICP account")
            .with_parameter(
                ic_llm::parameter("account", ParameterType::String)
                    .with_description("The ICP account to look up")
                    .is_required()
            )
            .build()
    ])
    .send()
    .await
