Model Sunset Lint

Finds every model ID and API parameter in your code that a vendor has already switched off or has published a date for - 109 rules across OpenAI, Anthropic, Google and Azure, each carrying the real shutdown date and the exact replacement string.

What it does for free

• Check the open file against all 109 rules - no key, no cap, no watermark
• Check only the lines you select
• Every hit carries the vendor, the real shutdown date and the replacement string
• error = already off today, warn = a date inside 120 days, info = later
• Read all 109 rules and their dates without running anything

With a licence

• Every file in the repository — One pass over the whole workspace instead of the file you happen to have open.
• Rewrite the retired IDs — Replaces each retired ID with its published replacement, in place, instead of only naming it.
• Dated inventory as CSV, JSON or HTML — The migration list you hand to a team, with dates, not a panel you read once.
• CI JSON so the build fails first — A pipeline gate that catches a retired ID before the shutdown date does.

A US software engineer averages $70.92/hour (ZipRecruiter, August 2026). $29 is about 25 minutes of that, once.
