In this blog post, we'll explore how to use ChatGPT in Rust with the help of the llm-chain
library. We will walk through a simple example that demonstrates how to generate responses using OpenAI's ChatGPT model.
Getting Started
First, let's start by installing the necessary packages using cargo add
. You will need the llm-chain
and llm-chain-openai
libraries:
cargo add llm-chain llm-chain-openai
Now, let's dive into the code:
use llm_chain::{traits::StepExt, Parameters};
use llm_chain_openai::chatgpt::{Executor, Model, Role, Step};
#[tokio::main(flavor = "current_thread")]
async fn main() {
let exec = Executor::new_default();
let chain = Step::new(
Model::ChatGPT3_5Turbo,
[
(
Role::System,
"You are a helpful assistant",
),
(Role::User, "Tell me about the Rust programming language"),
],
)
.to_chain();
let res = chain.run(Parameters::new(), &exec).await.unwrap();
println!("{:?}", res);
}
In the code snippet above, we begin by importing the necessary modules and functions from the llm-chain
and llm-chain-openai
libraries. We then define a simple main
function that uses the Executor
and Step
structs to create a conversational chain.
The Model::ChatGPT3_5Turbo
model is used as the language model in this example. We also define two steps in the conversation: the first one sets the role of the assistant and the second one asks a question about the Rust programming language.
Finally, we execute the conversation chain using the run
method and print the generated response.
Wrapping Up
As you can see, using ChatGPT in Rust with llm-chain
is a straightforward and efficient process. The library makes it easy to build and manage conversational agents in Rust, allowing developers to focus on creating more powerful and interactive applications.
