AI Model Sunset Watch: Bedrock Deadlines Pass Without Confirmed Retirement State | September 15, 2026

Two Amazon Bedrock model versions have passed their announced end-of-life dates. AWS’s official Legacy table still lists both versions, so the deadline alerts have changed while their actual post-deadline availability remains unconfirmed.

This report was prepared with AI assistance and checked against the cited official documentation. It distinguishes the provider’s announced dates from observed service availability and does not treat a passed date as proof of retirement.

Nova Premier v1 crosses its Bedrock EOL date

Source: Amazon Bedrock Legacy lifecycle documentation, verified September 15, 2026

Deadline: September 14, 2026, exact announced EOL date, now one calendar day past due. Model ID: amazon.nova-premier-v1:0.

Summary: AWS lists Nova Premier v1 as Legacy in us-east-1, us-east-2, and us-west-2, with a September 14 EOL date. The table still contains the row. The lifecycle notice does not identify a replacement in that row, and this check did not confirm whether requests now fail.

Why it matters: Teams should urgently check affected deployments and complete a tested migration to an eligible active model. AWS says availability ends on or soon after EOL, subject to private continued-access arrangements, and migration does not happen automatically.

Nova Sonic v1 crosses its Bedrock EOL date

Source: Amazon Bedrock Legacy lifecycle documentation, verified September 15, 2026

Deadline: September 14, 2026, exact announced EOL date, now one calendar day past due. Model ID: amazon.nova-sonic-v1:0.

Summary: AWS lists Nova Sonic v1 as Legacy in ap-northeast-1, eu-north-1, and us-east-1, with a September 14 EOL date. Its row also remains in the table. No replacement is specified in that lifecycle row, and actual post-deadline availability remains unconfirmed.

Why it matters: Owners of affected workloads should verify their provider state and test an active replacement rather than assume continued service or automatic migration. This warning applies to the listed Bedrock version and regions, not every model carrying the Nova Sonic name.

Coming next: lifecycle website and API

The Model Sunset Watch website and API are planned and not yet available. The intended service will expose searchable platform-specific records, warning bands, replacement mappings, source provenance, and machine-readable verification dates so developers can connect lifecycle evidence to their workload inventories.

Provider recommendations will remain separate from compatibility assessments. Any future continuity gateway will need explicit policy, workload evaluations, controlled cutovers, and recovery plans before promoting a replacement.
