TanStack AI 1.0 landed on npm on October 22, 2026, and the announcement post followed a day later. When we covered the beta in June, the pitch was the "Switzerland of AI tooling": any provider, any UI framework, the open AG-UI protocol on the wire, and no hosted platform attached. That pitch has not changed. What changed is the commitment behind it. The core APIs are now stable, 76 packages moved to 1.0 together, every API that 0.x had deprecated is gone, and a new agent harness ships beside the core as an explicitly experimental 0.x package. This post covers what "stable" includes, what landed between the August release candidate and 1.0, what an upgrade from 0.x costs, how the harness works, and what all of it means for Aliz projects.

TanStack AI reached beta on June 9, positioning itself as the "Switzerland of AI tooling" — framework-agnostic, provider-agnostic, and fully open-source with no hosted platform required. It's built by the same team behind React Query and TanStack Router, and it brings that same philosophy of composable, type-safe primitives to AI application development.

TanStack Virtual added chat-specific primitives in Tanner Linsley's May 25 announcement. Standard virtualization is start-anchored; chat UIs need end-anchored, prepend-safe, stream-aware scroll management. These primitives move that bookkeeping from hand-rolled state into a tested library.
