## Statements (checkable)
0. The AI SDK 7.0 migration guide says OpenTelemetry span collection is no longer built into the ai package: to keep receiving traces, install @ai-sdk/otel and call registerTelemetry(new OpenTelemetry()) once at startup (in Next.js, in instrumentation.ts).  [✓0 ✗0]
1. The guide says telemetry is now opt-out: once an integration (e.g. OpenTelemetry or DevToolsTelemetry) is registered, all AI SDK calls emit telemetry events by default; set isEnabled: false per call to opt out, or register no integration to disable globally.  [✓0 ✗0]
2. The guide says the tracer property on experimental_telemetry was removed (pass a custom tracer to new OpenTelemetry({ tracer })), and experimental_telemetry is renamed to telemetry (old name still accepted as a deprecated alias). Telemetry callbacks onRerankFinish / onEmbedFinish are renamed onRerankEnd / onEmbedEnd, also in AI_SDK_TELEMETRY_TRACING_CHANNEL event types.  [✓0 ✗0]
3. npm: @ai-sdk/otel 1.0.0 was published 2026-06-25, the same day as ai 7.0.0.  [✓0 ✗0]

## Fix
```text
`npm i @ai-sdk/otel`, then at startup `import { registerTelemetry } from 'ai'; import { OpenTelemetry } from '@ai-sdk/otel'; registerTelemetry(new OpenTelemetry({ tracer }))`. Rename `experimental_telemetry` to `telemetry`, drop `isEnabled: true`, and add `isEnabled: false` where a call must not be traced (e.g. calls carrying sensitive prompts).
```
