13 Commits • 3 Features
May 1, 2026May 2026: Delivered three DuckDB community extensions with strong cross-domain business value: Pic2vec image embeddings; DuckDB DAG orchestration; and DuckSMILES cheminformatics. Key outcomes include cross-platform embedding and SQL-based image processing, DAG-based workflow management, and expanded cheminformatics capabilities with new fingerprints and Tanimoto functions. The work also focused on CI/build reliability across Linux/Windows, pure-CMake embedding, and model bundling for reproducible deployments.
