UpTrain, an open-source framework for evaluating and enhancing LLM applications, has integrated with LlamaIndex to enable thorough assessments of Retrieval-Augmented Generation (RAG) pipelines. This collaboration allows developers to optimize their LLM-based applications by experimenting with various configurations and fine-tuning processes. UpTrain offers 20+ preconfigured checks for language and code applications, performing root cause analyses to help resolve failures, ensuring data security by conducting evaluations locally. The platform supports diverse experimentations with different models and prompts, and provides tools for comparing open-source and proprietary LLMs. It also introduces advanced evaluation techniques such as Sub-Question Query Generation and Reranking Evaluations, allowing for systematic testing and improvement of RAG pipelines. These capabilities help developers identify and rectify points of failure in the pipeline, ultimately enhancing the quality of generated responses and retrieved context.
