Single function for loading LLMs

[InAnYan]

LangChain has function init_chat_model (https://python.langchain.com/api_reference/langchain/chat_models/langchain.chat_models.base.init_chat_model.html).

This function allows to instantiate any LLM model (from any "company") in one line.

I find it very useful for my scripts. Does LlamaIndex has something similar?

LlamaIndex does not have a single function like LangChain's init_chat_model for instantiating language models in one line. However, LlamaIndex provides a flexible framework to instantiate and use language models from various providers, but it requires a few more steps. You can set up models from providers like OpenAI, Hugging Face, and others by following specific instructions for each provider ^[1].

Maybe I should've create a feature request?

Filed as #18250. Discussed there too.

On the moment, LlamaIndex doesn't have these functions.
