- Worth noticing
- The illustrative OpenAI migration names 212 tests, while its animation also shows a moment with 0 of 212 passed.
Field notes
The page lays out a workflow from provider announcement to changed call sites, sandbox run, and pull request, with human review kept as the merge gate. Its illustrative migration names specific upgrade paths, including OpenAI Python SDK v0 to v1 and Firebase v8 to v9. The page says Sunup is onboarding design partners; the demo is explicitly illustrative, so it does not establish that the described migrations are already running in production.
