Vespa Newsletter, May 2023

The May 2023 Vespa Newsletter highlights significant updates, including the introduction of multi-vector HNSW indexing, which addresses the limitation of representing data items with a single vector by allowing indexing of multiple vectors per document. Additionally, Vespa now supports declarative global re-ranking, enabling GPU-accelerated inference to optimize search ranking without writing code. Integration with LangChain allows Vespa to act as a data source for language model-powered applications, and several optimizations have been introduced, such as improved bfloat16 tensor operations and new features in the Vespa Cloud Dev Console. The newsletter also mentions the availability of Vespa on Docker Hub without rate limits and outlines the benefits of using the Vespa CLI for data management. Subscribers are encouraged to keep up with updates via the Vespa Blog RSS feed and are reminded of Vespa's daily production releases for enhanced security and performance.
