Hosted skills are now supported in TanStack AI. 🧩

Pass { skills } to your code-execution tool, TanStack AI lifts them into container skills and auto-wires the beta headers.

Anthropic + OpenAI. 🚀

A tool returns an image of a secret number. The model reads it back. 👁️

TanStack AI now supports multimodal tool results: return an Array<ContentPart> with an image part and the model sees the actual pixels - not a stringified blob.

Your AI chat vanishes on every page reload? 🔄

TanStack AI just shipped a persistence option: pass one adapter and conversations hydrate on load, save on change, clear on reset. localStorage, IndexedDB, anything.

One adapter. Every OpenAI-compatible provider. 🔌

openaiCompatible({ baseURL, apiKey, models })

Connects DeepSeek, Kimi, Together, Fireworks, Qwen, local LM Studio/vLLM, and more.

Type-safe model unions, no package per vendor.

One of the cooler parts of their writeup: When AI is generating full apps, framework primitives are a direct translation to product quality, so typed routing, clear server/client boundaries, server functions, and route-level rendering choices act as both guardrails for the apps your users create and a measurable lever for user experience.

New @Lovable projects now ship on TanStack Start.

That means full-stack React with SSR/SSG/CSR per route, server functions colocated with components, deploy-anywhere architecture, and type safety that helps both humans and AI generate better apps.

One of our packages was incorrectly flagged as malicious today as part of the broader false-positive wave affecting a number of widely trusted packages across the ecosystem.

We’ve manually reviewed the published artifacts for the flagged version and can confirm they are clean.

A bit concerning that the first indication we received about the malware flag was via social media instead of a direct notification or outreach process. Hoping the reporting flow around issues like this can improve going forward.

TanStack Virtual now has first-class chat support: end anchoring, append-follow, stable prepends, and streaming messages that stay pinned when they should.

The modern web is now a lot of streaming UI on top of lists, so this needed to feel boring 😉
