# Chat 3.0 (beta)

Chat 3.0 handles open-ended, multi-part questions in a single conversation. It decomposes a question into sub-queries, executes each one, compares the results, and combines them into a final answer.

Every result, whether it's a table, chart, query, or written response, is stored as a persistent artifact you can return to. You can edit any artifact directly or hand it back to Lumi to continue refining it. Each edit is saved as a new version, and artifacts support in-thread comments and review.

What's new in Chat 3.0:

* **Multi-step reasoning:** Lumi decomposes a question into sub-queries, runs each one, and combines the results into one answer.
* **Persistent artifacts:** Every result, whether it be a table, chart, query, or written response, is now a persistent object you can return to and build on.
* **Direct editing:** Edit any result yourself, from a chart to a query, then hand it back to Lumi to continue from your edited version.
* **Version control:** Every version of an artifact is saved, so you can revert to an earlier version at any time.
* **In-thread comments and review:** Discuss, question, approve, or refine a specific result directly in the chat.
* **Focus mode:** Drill into a specific result while keeping the rest of the conversation on standby.

Chat 3.0 is currently available in beta. To turn it on, look for the Chat 3.0 toggle near the top of the left sidebar and switch it on. You can switch it back off at any time to return to the Chat Classic experience.
