TURBOPACK CUTS BUILD CACHE MISSES, AI SDK GRADUATES EXPERIMENTAL FEATURES

Next.js shipped two critical Turbopack optimizations that slash task cache misses by 74%, while Vercel AI SDK promoted five experimental APIs to stable—the biggest API surface shift since launch.

The Turbopack team is methodically cutting task overhead. First, they eliminated `ReferencedAsset::from_resolve_result` as a turbotask [1], a change that addresses a task that was executing 1.9M times with only a 74% hit rate. Then they simplified asset ident constructors [2], converting per-method turbotasks into plain Rust builders with a single final `into_vc()` call—less ceremony, same output, faster caches. These changes compound: fewer turbotasks mean fewer scheduler decisions, faster builds, and cleaner compilation graphs. Request store handling got a cleaner API too [3], decoupling store creation from HTTP primitives so consumers can build stores from serializable inputs instead of concrete `req`/`res` pairs. Meanwhile, Vercel AI SDK is graduating experimental features: `include` is now stable [7], replacing `experimental_include` for controlling response content; tool metadata has a dedicated path [4] instead of merging into provider metadata; and deprecated callbacks [6] are back for SDK 6 compatibility. The `includeRawChunks` option moved to `include.rawChunks` [5]. On Turborepo, two security hardening PRs landed: local devtools WebSocket now requires per-session token validation [8] instead of permissive CORS, and OTel endpoint validation [9] rejects malformed URLs before initializing exporters. CLI got two small wins [10] skips SAML-limited teams during `vercel link` auto-detection, and [11] adds `--error` flag for manual deployment continuation.

Action items

→ Rebuild Next.js projects with latest main to benefit from Turbopack cache improvements vercel/next.js [plan]
→ Update Vercel AI SDK code: migrate experimental_include → include, remove deprecated experimental_onToolCall* if upgrading beyond SDK 6 vercel/ai [plan]
→ Verify local Turborepo devtools work with new token-based WebSocket auth if you're on main vercel/turborepo [monitor]
