TigerGraph GraphRAG v1.4.1

GraphRAG 1.4.1 adds token-based sign-in and a pre-flight upload conflict check, plus a wave of ingestion-UX, image-description, and reliability fixes.

What's New

  • Token-based sign-in — sign in with an API token or shared secret in addition to username and password. The signed-in identity, including real username and roles, is shown consistently across the UI.
  • Pre-flight upload conflict check — uploads warn about filename collisions before sending the bytes and offer a one-click choice to replace or skip the conflicting files.

Changed

  • Per-graph image-description controls — new extract_images toggle and min_image_dim_px threshold on the GraphRAG Configuration page, settable globally or per graph. Disable image description on graphs that don't need it, or raise the dimension threshold to skip more small images.
  • Faster image-heavy PDF ingestion — PDFs with many images ingest significantly faster, decorative images are excluded from the graph, and image descriptions are written in the document's own language.
  • Multilingual answer fidelity — the chatbot answers in the question's language, quotes exact numbers and units from the source, and lists candidates before stating a maximum, minimum, or other comparison conclusion.
  • Community search falls back to hybrid on miss or failure — auto-selected community questions that find no relevant summaries are retried with hybrid search instead of returning a "couldn't find" answer.

Bug Fixes

  • Sample documents disappeared from the upload dialog after schema extraction — they now stay visible in the dialog after extraction. Re-uploading the same filename triggers a clean re-extract on the next ingest.
  • Chat disconnected on vector-store errors — chat stays open through transient vector-store problems. Graph-traversal questions answer normally; only questions that strictly need vector search fail per-question with a clear message.
  • Ingest button enabled when reopening the dialog mid-conversion — could trigger a double upload. The button now correctly reflects the current job state on reopen, and the uploaded-files list refreshes.
