Anthropic retires Claude 4 Opus and Sonnet models on June 15

By PulseAugur Editorial · [1 sources] ·

Anthropic is retiring specific versions of its Claude 4 Opus and Sonnet models, claude-opus-4-20250514 and claude-sonnet-4-20250514, on June 15, 2026. This deprecation affects not only direct calls to these snapshot IDs but also the versioned aliases like `claude-opus-4-0` and `claude-sonnet-4-0` that resolve to them. Developers using these models should update their code to reference newer versions, such as `claude-opus-4-1`, and be aware that partner platforms like AWS Bedrock and Google Vertex AI may have different retirement schedules. Additionally, teams relying on mocked SDK tests or model-router fallback configurations need to implement integration tests against live APIs to ensure their systems do not silently fail after the June 15 deadline.

IMPACT Developers must update integrations to avoid service disruptions from retired model versions.
