Conversation
Bumps `ai` 6.0.161 -> 7.0.64 across the workspace, with the provider
packages moved to their v7-line majors (@ai-sdk/openai 4, anthropic 4,
google 4, openai-compatible 3, react 4). Versions are pinned to releases
that clear the workspace's 7-day minimumReleaseAge gate rather than
excluding them from it.
Three v7 changes bite, and only the first is visible to the compiler.
**System messages are rejected in `messages`.** v7 throws
InvalidPromptError when a `role: "system"` entry appears in `messages` or
`prompt` (v6 only warned). Four call sites hit this and all typechecked
clean, so nothing would have caught it before a request ran:
dataset-generate, both workflows routes, and the scenario prompt-config
adapter. Each hoists its system prompt to the top-level `instructions`
option. The prompt-config adapter and the playground additionally pass
`allowSystemInMessages: true`, because their transcripts carry
user-authored turns that v6 accepted and a hard throw would be a
regression for the people who wrote them. dataset-generate deliberately
does not: its `messages` is unvalidated client input, so rejecting a
client-injected system turn is the behaviour we want.
**Telemetry is off until it is registered.** v7 moves OpenTelemetry out
of `ai` and into `@ai-sdk/otel`; `experimental_telemetry: { isEnabled:
true }` on its own now emits zero spans. Verified against 7.0.64: two
spans on v6, none on v7, three once `registerTelemetry(new
OpenTelemetry())` runs. The SDK examples, the docs integration page and
the in-product onboarding snippet all taught the v6 shape, so a customer
following our own instructions on v7 would have sent us nothing and
concluded LangWatch was broken. All three now register the integration.
**The instrumentation scope was renamed.** AI SDK spans arrive under
scope `gen_ai` on v7, not `ai`, so `isVercelAiSpan` — and with it the
`vercelAIOnly` exporter preset — silently discarded every AI SDK span
from a v7 app. It now matches both, with a regression test.
Also renames the deprecated aliases still in use (`system:` ->
`instructions:`, `stepCountIs` -> `isStepCount`) and corrects a stale
`usage.completionTokens` (v4 spelling) in the metadata example.
Node floor moves to 22, which `ai@7` requires; skills-publish was still
on 20.
Adds `dev/docs/best_practices/ai-sdk.md` (indexed in the README) and four rows to CLAUDE.md's table. The doc leads with the thing that actually cost time during the migration: v7 kept deprecated aliases for nearly everything it renamed, so broken code typechecks clean. It covers `instructions` vs system messages and when `allowSystemInMessages` is legitimate, telemetry registration and the `ai` -> `gen_ai` scope rename, resolving models through `getVercelAIModel`, all-step result aggregation, and asserting on `instructions` in tests. Sweeps the customer docs, which uniformly taught a pattern that sends us nothing on v7. Eight pages now register the `@ai-sdk/otel` integration and carry a note for readers still on v6, and the debug-instrumentation skill says the same (docs/skills/directory.mdx is generated from it via sync-prompts.sh, not hand-edited). Two of those pages were wrong in a way worth calling out: the prompt-management examples pipe `compiledPrompt.messages` straight into `generateText`, and a compiled LangWatch prompt carries the customer's system turn inside that array — so on v7 our own prompt-management quickstart threw. They now pass `allowSystemInMessages: true`, which is the case the flag exists for: turns the customer authored themselves. Fixes a real ingestion gap found while checking the docs were accurate. @ai-sdk/otel reports time to first chunk as `gen_ai.client.operation.time_to_first_chunk`, but the canonicaliser only recognised the semconv v1.41 `gen_ai.response.time_to_first_chunk`, so TTFT was silently dropped for every AI SDK 7 app. Same seconds unit, so it folds into the existing rule. Token usage needed no change — `gen_ai.usage.input_tokens`/`output_tokens` were already handled. Also corrects two stale AI SDK v4 spellings the sweep surfaced: `maxTokens` (now `maxOutputTokens`) in the TypeScript guide, and the `ai.usage.promptTokens` attribute names in the cost tutorial.
…ion onto main The migration branch this rebases on top of was 24 commits behind origin/main. `pnpm install --lockfile-only` picks up the drift so the lockfile matches the package.json versions the migration commits set.
#7236 grouped `ai` 6.0.217->7.0.60 with `@ai-sdk/react` 3.0.219->4.0.63 into one PR via the existing `ai-sdk` group, and the build still broke: @ai-sdk/react@4.0.63 imported Experimental_AbstractRealtimeSession, which ai@7.0.60 didn't export yet. `patterns` only bundles matching packages into one PR — it never checks that the versions it lands on actually work together. Peer-dependency resolution doesn't help here either: @ai-sdk/react depends on `ai` as a normal (non-peer) dependency pinned to an exact version internally, so pnpm never sees the two as linked and raises nothing when they drift. Vercel publishes each ai-sdk package as an independent npm release even though the versions are meant to move in lockstep, so two packages a few days apart in publish time can each individually clear the cooldown while still being a broken pair. Raises the major-bump cooldown to 14 days so a freshly-published major line has more time for every sibling package to catch up before dependabot proposes any of them. This doesn't make a pairing provably compatible — only CI running the real build does that, which is exactly what caught #7236 before it merged.

generateText's messages must not be empty even when the whole conversation lives in `instructions` (v6 always had the system message itself to fall back on; v7 hoisted that out). A template that reads the conversation itself, with no template messages configured, was leaving `messages` empty and throwing AI_InvalidPromptError at runtime -- invisible to the mocked unit tests, but caught by the real integration test against a live model. Falls back to just this turn's new message so the model still has something to reply to, without re-showing the history the template already rendered.
CodeRabbit review fixes: - genAi.ts: gen_ai.response.time_to_first_chunk was selected whenever the key was merely present, even with an invalid/negative value, silently shadowing a valid gen_ai.client.operation.time_to_first_chunk. Select the first validated, non-negative value instead. - otelSemconv.test.ts: assert the source attribute is actually deleted after canonicalisation, not just that the canonical key is set. - prompt-config.adapter.ts / its unit test: drop two comments that only restated the line below them. - ai-sdk.md: add a language identifier to the ASCII diagram fence (markdownlint MD040).
CodeRabbit review fixes:
- quick-start.mdx / typescript/guide.mdx: the telemetry examples import
`registerTelemetry` and `OpenTelemetry` from `@ai-sdk/otel`, but the
install commands above them never listed the package. Our own
dev/docs/best_practices/ai-sdk.md already calls this out as the
exact gap that leaves a customer with silent zero-span telemetry.
- multiple-providers.mdx: the isolation guide's Note incorrectly said
`@ai-sdk/otel` always sends spans to the global provider. It accepts
a custom tracer via `registerTelemetry(new OpenTelemetry({ tracer }))`,
so it can be routed to the isolated provider like everything else in
this guide, without losing the standard GenAI span attributes.
- docs/llms-full.txt regenerated (`node docs/llms.txt.cjs`) to match.
# Conflicts: # pnpm-lock.yaml
The v6-compat Note only said "drop those two lines" but three things change: the registerTelemetry import, the @ai-sdk/otel import, and the registerTelemetry(new OpenTelemetry()) call. Spell out all three. docs/llms-full.txt regenerated (node docs/llms.txt.cjs) to match.

# Conflicts: # pnpm-lock.yaml
Second round of CodeRabbit review fixes (re-review after the previous push):
- genAi.ts: `recordRule` always logged the "response" rule name even when
the client-sourced value was selected. Derive the rule suffix from
which source actually won, and rename `useResponseTime` ->
`isResponseTime` to match the boolean-naming convention.
- otelSemconv.test.ts: added the two missing precedence branches (valid
response beats a valid client value; a negative/invalid response falls
back to a valid client value) -- the "existing value wins" branch was
already covered.
- typescript/guide.mdx: the dependency Note still said only
`@ai-sdk/openai` and `ai` were required, even though the example also
imports `@ai-sdk/otel`.
- multiple-providers.mdx: clarified that `lwProvider.getTracer("gen_ai")`
only reconfigures `@ai-sdk/otel`, not other auto-instrumentations.
- prompt-management/{getting-started,features/advanced/link-to-traces}.mdx:
both TypeScript tracing examples called `generateText` without
registering AI SDK 7 telemetry, so they'd silently produce empty
traces. Added `registerTelemetry(new OpenTelemetry())` to both, plus
the matching `allowSystemInMessages` flag getting-started.mdx was
missing.
- Deleted 4 more restating comments (metadata example x2, vercel-ai
example x1, prompt-config adapter unit test x1) per the repo's
"comments explain why, not what" rule.
- docs/llms-full.txt regenerated (`node docs/llms.txt.cjs`) to match.
Keeps the ai-sdk 7 bump for @ai-sdk/anthropic and takes main's newer @anthropic-ai/claude-code pin. Corrects the CJS note in ai-sdk.md: ai@7 being ESM-only is not a blocker, because Node loads it through require() unflagged from 22.12 and the app's own server.cjs already does so.

Flagging a runtime blocker that this PR's green CI does not catch, because it lives inside a vendored tarball. This PR sets
The consequences were established in detail on #7279, which carries the byte-identical override (same integrity hash, same resolution):
To be precise about provenance: I verified the override, the lockfile resolution and the tarball's declared ranges on this branch directly. The runtime errors above were reproduced against the real published packages on #7279, not re-run here. Note this PR already carries CI is green because nothing in the suite executes a scenario run through the vendored bundle. Worth holding the merge until a re-vendored tarball exists. |

Cross-reference from driving #7279: the merge blocker documented there applies to this PR identically, and this PR's body doesn't mention it. Both PRs carry the same workspace-wide Separately: this PR and #7279 look like two takes on the same migration (created 30 minutes apart, 44 files each, same override, same call-site hoists). Worth consolidating to one before upstream ships so the re-vendor lands exactly once. |

What broke
#7236 (dependabot's grouped
ai-sdkupdate) bumpedai6.0.217 -> 7.0.60 and@ai-sdk/react3.0.219 -> 4.0.63 in the same PR, and theplatform/appbuildfailed:
Both packages were in dependabot's existing
ai-sdkgroup (@ai-sdk/*+ai),so they landed in one PR as intended — but
@ai-sdk/react@4.0.63importsExperimental_AbstractRealtimeSessionfromai, and theaiversion dependabotpicked didn't export it yet.
Root cause, confirmed by inspecting the installed packages:
@ai-sdk/reactdoes not declare
aias apeerDependency— it depends onaias a normaldependency pinned to an exact version internally (
"ai": "7.0.64"in its ownpackage.json). pnpm's peer-resolution never sees the two packages as linked,so nothing errors when their versions drift apart. Vercel publishes each
ai-sdkpackage as an independent npm release even though the family is meantto move in lockstep, so two packages a few days apart in publish time can each
individually clear dependabot's cooldown while still being an incompatible
pair. Grouping into one PR bundles the presentation; it does not validate
that the chosen versions actually work together.
What this does
1. Fixes the mismatch by moving the whole
ai-sdkfamily to their v7-linemajors, verified compatible against the actual npm registry rather than
guessed:
ai@ai-sdk/react@ai-sdk/openai@ai-sdk/openai-compatible@ai-sdk/anthropic@ai-sdk/googleAcross
platform/app,mcp/typescript,skills/, and thesdks/typescriptexamples — everywhere the family is declared. Node engine floor moves to
>=22(ai@7requires it; every workflow already runs Node 24 exceptskills-publish.yml, which is bumped to match).v7 has three behavior changes that bite at runtime, invisible to the
typechecker because v7 kept deprecated aliases for nearly everything it
renamed:
messagesnow throw (InvalidPromptError) insteadof warning. Four call sites (
dataset-generate, bothworkflowsroutes,the scenario prompt-config adapter) hoist their system prompt to the
top-level
instructionsoption instead. The prompt-config adapter and theplayground also pass
allowSystemInMessages: true, since their transcriptslegitimately carry user-authored system turns.
aiinto@ai-sdk/otel—experimental_telemetry: { isEnabled: true }alone now emits zero spans. All customer-facingsnippets (docs, SDK examples, onboarding codegen) now register the
integration.
ai->gen_ai—isVercelAiSpan(and the
vercelAIOnlyexporter preset) now matches both, with aregression test, so a v7 app's spans aren't silently dropped.
Also fixes an ingestion gap found while updating the docs:
@ai-sdk/otelreports time-to-first-chunk under a v1.41 semconv name the canonicaliser
didn't recognize, so TTFT was silently dropped for every v7 app.
pnpm typecheck,pnpm typecheck:tests, the clientvite build, and thetouched unit tests (prompt-config adapter, otelSemconv, scenario-generate,
ai-query, trace-filters) all pass locally.
2. Tightens
.github/dependabot.ymlso the exact failure mode is lesslikely to recur: raises
cooldown.semver-major-daysto 14 for the npm rootentry. The existing
ai-sdkgroup pattern (@ai-sdk/*+ai) alreadycovered every affected package correctly — grouping wasn't the gap, timing
was. A longer major-bump cooldown gives a freshly-published major line more
time for every sibling package to catch up before dependabot proposes any of
them. This doesn't make a pairing provably compatible — only CI running the
real build does that, which is exactly what caught #7236 before it merged.
Closes the mismatch from #7236, which is being closed in favor of this PR
(dependabot will re-propose future ai-sdk bumps against these new versions).
Deployment Impact
No env vars, Helm values, or
helm installdefaults change — this PR onlytouches
package.json/lockfile dependency versions anddev/docs/best_practices/docs (which is what triggers this gate; no
charts/,services/, or.env.examplechanges). No new runtime configuration is introduced.The one operator-relevant change is the Node engine floor moving from
>=20to
>=22(ai@7requires it, rootpackage.json). Every CI workflow and the production image already buildon Node 24, so this doesn't change deployed behavior — it only affects a
self-hoster building from source on an older Node version, who would now need
to upgrade their build toolchain. No BYOC dataplane impact: the AI Gateway
(Go,
services/aigateway/) and NLP engine (Go,services/nlpgo/) areunaffected, since
ai-sdkis a TypeScript-only dependency.ai@7ships no CommonJS entry point (itsexportsmap carries onlyimport/default), and the production entrypoint is a CommonJS bundle:platform/app/scripts/build-server.mjsemitsdist/server/server.cjswithformat: "cjs"and keeps third-party packages external, so the running serverdoes
require("ai")against an ES module. That works because Node loads ESMthrough
require()unflagged from 22.12 on, which the>=22floor aboveguarantees — so this needs no action. It is written up in
dev/docs/best_practices/ai-sdk.mdbecause the one thing that would break itis a future
airelease introducing top-level await:require()would thenthrow
ERR_REQUIRE_ASYNC_MODULE, on a patch bump, visible only to CommonJSconsumers.
Test plan
pnpm typecheck(platform/app, scoped)pnpm typecheck:tests(platform/app, scoped)NODE_ENV=production vite build(platform/app client) — confirmsExperimental_AbstractRealtimeSessionresolves and the build succeedspnpm test:uniton the touched files: prompt-config adapter (19passed), otelSemconv (36 passed), scenario-generate + ai-query error
paths (9 passed), sdks/typescript trace-filters (50 passed)
generateText'smessagesarray must be non-empty even when the wholeconversation lives in
instructions(v6 always had the system messageitself to fall back on).
SerializedPromptConfigAdaptercould hand itan empty array when a template reads the conversation itself with no
template messages configured, throwing
AI_InvalidPromptErroratruntime — invisible to the mocked unit tests, caught by the real
prompt-config-multi-turn.integration.test.tsagainst a live model.Now falls back to just the turn's new message. Also applied CodeRabbit's
review fixes: a TTFT canonicalisation edge case (an invalid/negative
gen_ai.response.time_to_first_chunkwas shadowing a validgen_ai.client.operation.time_to_first_chunkinstead of falling back toit), two docs fixes (install commands missing
@ai-sdk/otelwhere theexample imports it; a multiple-OTel-providers guide that incorrectly
said
@ai-sdk/otelcan't be pointed at an isolated tracer, when itaccepts one via
registerTelemetry(new OpenTelemetry({ tracer }))),plus two restating comments and a markdownlint fence. Rebased onto
maintwice to pick up unrelated dependency churn that landed whilethis branch was open (
pnpm-lock.yamlconflicts only, regenerated viapnpm install --lockfile-only; the ADR-092 authz-engine merge auto-merged cleanly aside from the lockfile). Second CodeRabbit round caught
two more real gaps: two TypeScript prompt-management tracing examples
called
generateTextwithoutregisterTelemetry, so they'd silentlyproduce empty traces exactly like the bug this PR exists to fix; and
the TTFT fix's
recordRulecall always logged the "response" rulename even when the client-sourced value won. Both fixed, plus four
more restating comments removed and two more test branches added.
