LlamaIndex newsletter 2023–10–24

The newsletter highlights recent developments and offerings from LlamaIndex, including the launch of the QueryFusionRetriever, designed to enhance query generation using large language models (LLMs), and an innovative router fine-tuning approach that achieved a 99% match rate, outperforming existing models. The company has expanded its LLM compatibility by integrating with Amazon Bedrock and AI21 Labs models and introduced several new tools and guides, such as the SQLRetriever merging Text-to-SQL and RAG for structured database queries. Tutorials cover complex query resolutions and domain-specific fine-tuning, while new collaborations with Gradient AI and PrivateGPT aim to streamline integration of fine-tuned LLMs and enable private document interactions. Other integrations include DashVector, Tencent Cloud, and PGVectorStore enhancements to support custom Postgres schemas. Webinars featured include a workshop on Evaluation-Driven Development and a showcase of projects from the AGI House hackathon.
