On 14 October 2026, the Seafile team opened testing for version 14.0, headlined by AI Chat — an assistant that explores your libraries through their metadata — and SeaSearch, a full-text and vector search engine now set as the default.

Amazon S3 Vectors now evaluates the metadata filter before the similarity search, returning up to 5 times more relevant vectors on highly selective filters. Enabling it is free, in place and re-ingestion-free: switch your indexes to ENHANCED mode.

Retrieval-Augmented Generation is no longer a buzzword: it’s the truth layer that stops LLMs from inventing answers about your own documents. Here are the architectures, models, and traps that separate a PoC from a production deployment.
