## NEO-2 additions over NEO-1

- **DuckDuckGo web search** — real queries when the knowledge base has no answer
- **License filtering** — only uses CC BY, CC0 or Public Domain sources; blocks All Rights Reserved, CC BY-ND, CC BY-NC
- **Abstractive summarization** — builds original prose from search results, never copies verbatim
- **Session cache** — avoids re-searching the same query (up to 50 entries)
- **Automatic retries** — retries up to 2 times with pause on network failure
- **Typed errors** — distinguishes network failure, rate-limit and no-results for clear user messages

## All NEO-1 features included

JSON knowledge base · token similarity · response variation · streaming · calculator · Roblox API · closed edition · NeoAPI REST
