## LlamaIndex Reviews
  ### 1. Linking some datasets to my AI apps

**Rating:** 4.5/5.0 stars

**Reviewed by:** Shihab R. | Principal Project Manager, Financial Services, Small-Business (50 or fewer emp.)

**Reviewed Date:** October 26, 2024

**What do you like best about LlamaIndex?**

As a data scientist dealing with large language models LLMs I found LlamaIndex quite helpful to manage. It has granted me the ability to input data in formats such as PDFs or API, databases and excel, which makes it easier for me to train and execute LLMs with numerous datasets.

**What do you dislike about LlamaIndex?**

This is where the perceived level of control over natural language processing (NLP) in the platform is somewhat constrained.  Specific to pipeline needs or how the language model is resolved, there is less fine-grained control than directly coding within the LLM context provided by LlamaIndex.

**What problems is LlamaIndex solving and how is that benefiting you?**

LlamaIndex makes it very easy to load, store and index data that needs to be used with LLMs.  This means that I do not have to spend time and effort in various aspects of data preprocessing that may hamper the basic modeling and analysis.
