In the era of advanced language model applications, developers and data scientists are continuously seeking efficient tools to build, deploy, and manage their projects. As large language models (LLMs) like GPT-4 gain popularity, more people are looking to leverage these powerful models in their own applications. However, working with LLMs can be complex without the right tools.

That’s why I’ve put together this list of five essential tools that can significantly enhance the development and deployment of LLM-powered applications. Whether you’re just beginning or are a seasoned ML engineer, these tools will help you be more productive and build higher-quality LLM projects.



Hugging Face is more than just an AI platform; it’s a comprehensive ecosystem for hosting models, datasets, and demos. It supports various frameworks allowing users to train, fine-tune, evaluate, and generate content in multiple forms like images, text, and audio. The combination of a vast model selection, community resources, and developer-friendly APIs in one platform is why Hugging Face has become a go-to destination for many AI practitioners and ML engineers.

LangChain is a tool that uses a composability approach to build applications with LLMs. It is widely used to develop context-aware applications by integrating different sources of context with language models. Additionally, it can use a language model to reason about actions or responses based on the context provided. The LangChain AI team has recently introduced LangSmith, a new tool that provides a unified development platform to increase the speed and efficiency of LLM application production.
