LiteLLM is an open-source library designed to streamline LLM completion and embedding calls. With its user-friendly interface, LiteLLM makes it easy to interact with various LLM models efficiently.
To get started with LiteLLM, first, import the 'litellm' library and configure the required environment variables for your LLM API keys, such as OPENAI_API_KEY and COHERE_API_KEY. After setting these variables, you can develop a Python function to make LLM completion calls using LiteLLM. This powerful tool also offers a demo playground, enabling you to compare various LLM models by writing Python code and examining the outputs.
