TigerGraph GraphRAG v2.0.2
GraphRAG 2.0.2 adds data-integrity checks and targeted repair to the Migration Assistant, makes Agentic mode resilient across current and future models, and fixes rebuild, extraction, and chat issues.
What's New
- Migration Assistant data-integrity checks and targeted repair — the Migration Assistant now reports, per graph, how many vertices are missing embeddings (by type) and how many communities have a placeholder or empty summary, and can re-embed or re-summarize just those items without running a full rebuild. Items whose source content is unusable are flagged as needing a rebuild.
Changed
- Agentic mode works with current and future tool-calling models automatically — whether the chat model can drive Agentic mode is now determined by a runtime check (cached, re-checked after a restart) instead of a fixed model list, so current and future models — including Gemini 3.x and other providers — enable Agentic mode without a code change; a model that can't tool-call falls back to the Classic engine.
- Fewer dead-ends on structured questions — when the Planned agent's structured query returns nothing, it now runs a document search before answering, so an empty structured result no longer produces a non-answer.
- Clearer "can't answer" message — when the assistant can't produce an answer, it suggests rephrasing the question and contacting an administrator, instead of a bare failure notice.
- Per-service token cost rates — LLM Config accepts optional input/output USD-per-1M-token rates for the completion, chatbot, and multimodal services, so Est. Cost is accurate for models the pricing library doesn't recognize.
Bug Fixes
- Rebuild no longer fails on document names containing parentheses — names with
(or)are normalized without dropping the rest of the name, so rebuilds complete instead of erroring while creating chunks. - PDF chart labels and table numbers survive extraction — picture-text blocks stay intact, stacked and comma-grouped chart values are no longer glued together, and pages with unreadable embedded fonts are recovered from a page image, so figures and tables reach the graph with their numbers intact.
- Chat Stop button behaves correctly — stopping a response just as it finishes no longer sends a stray empty message, and the button is the right size in the light theme.
