Llama Index v0.14.23 Release Notes

Llama Index released version 0.14.23 on June 24, 2026, introducing significant multimodal capabilities and various bug fixes. The core update includes multimodal synthesis features and the introduction of multimodal query engines to support diverse data types. Key fixes address document and video block handling within FunctionTool outputs and ensure URL-backed memory blocks are preserved correctly. Performance improvements were implemented by using sets for within-batch deduplication in the ingestion pipeline and optimizing token text splitting logic. The release also resolves a ZeroDivisionError on empty input sequences and fixes recursion errors in splitters when units exceed chunk sizes. Additionally, explicit UTF-8 encoding was added to file I/O operations, and deep copying of initial states prevents mutation leaks across workflow runs.
