- - If your project requires integration with OpenAI or other LLM APIs due to the availability of the `llm-chain-openai` sub-crate.
Avoid when
- - If your development stack is predominantly in languages that cannot easily integrate Rust libraries, such as Python-dominant environments.
- - For teams lacking Rust proficiency since setting up and using `llm-chain` requires proficiency with Rust's package management and compilation process.

Getting Started 🚀
To start using llm-chain, add it as a dependency in your Cargo.toml (you need Rust 1.65.0 or newer):
[dependencies]
llm-chain = "0.12.0"
llm-chain-openai = "0.12.0"
The examples for llm-chain-openai require you to set the OPENAI_API_KEY environment variable which you can do like this:
export OPENAI_API_KEY="sk-YOUR_OPEN_AI_KEY_HERE"
Then, refer to the documentation and examples to learn how to create prompt templates, chains, and more.
