## What it is
llm-chain is a Rust crate for building chains of large language model calls to complete complex tasks such as text summarization. It provides a LangChain-style framework for composing LLM workflows in Rust.

## Use cases
- summarize long documents with an llm in rust
- chain multiple llm prompts together
- build a langchain-style pipeline in rust
- run chatgpt or llama chains for complex tasks
- compose llm workflows with templates

## When to choose
- you are building llm applications in rust
- you need to chain llm calls for multi-step tasks like summarization
- you want a langchain alternative with native rust performance

## When to avoid
- you need a mature ecosystem with many integrations and active development
- your project is in python where langchain has broader support
- you need cutting-edge agent features updated frequently

## Facets
- artifact type: library
- maturity: maintenance
- function: llm-inference, agent-framework, prompt-engineering, rag
- domain: large-language-models, artificial-intelligence
- platform: rust, cross-platform
- tags: langchain, llm-chains, openai, llama, text-summarization, chatgpt, natural-language-processing
