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. Review collected by and hosted on G2.com.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. Review collected by and hosted on G2.com.
