Before you switch

A replacement model answers the same prompt differently: tone, length, format, and whether JSON still parses. Driftline Pro runs your real prompts on gpt-5.5-cyber-preview and the replacement side by side in CI and shows what changed. See a drift test.

Check your code for it

Run this in your repository. No install and no API key; it lists every OpenAI, Anthropic and Google model ID it finds, with its retirement date and replacement:

npx -y @aidriftline/driftline .

Or look for this ID only: grep -rn "gpt-5.5-cyber-preview" . (misses aliases, Bedrock and Vertex names, and IDs split across lines).

To be warned automatically before the next retirement, add the free Driftline GitHub Action. It annotates the exact line in pull requests and can fail the build on retired models.
