What's New in OpenCone
3.1
October 2, 2026
• Answers render headings, lists, tables and code, and every claim links to the passage it came from. • Search wider or narrower: Auto picks the indexes for each question, Everything searches every namespace of every index, and One index searches just one. • Follow-up questions now see your earlier exchanges. • Answer settings follow the model you pick: its own reasoning levels, answer length up to its maximum, detail, service tier and web search. • New Endpoints screen in Settings shows every OpenAI and Pinecone call, its settings and how it went. • A cleaner Documents tab: where uploads go, progress, and each file's indexing steps. New indexes use the cloud, region and metric you choose. • Fixed: answers appearing twice, tables overlapping their rows, and a document's row not updating after indexing.
