Pricing, context window and lifecycle for anthropic/claude-opus-4.1, tracked from what the vendor publishes.
2026-08-05 - this model has a published shutdown date. If your product calls it, you have a migration deadline.
2027-01-08 - this model is still served on AWS Bedrock after its vendor stopped serving it. Which date applies to you depends on where you call it, not on which one is newer.
To find every place that calls it before then:
curl -sO https://neosignal-ai.vercel.app/check.py
python check.py .
It names every model your repository calls that is already gone, and exits non-zero so the next one fails the build instead of production.
