Anthropic Claude model deprecations on June 15, 2026

Anthropic is deprecating two Claude models on June 15, 2026. After that date, scenarios using these models will fail.

What's changing?

The following models will no longer be available on the Anthropic Claude API starting June 15, 2026:

• Claude Sonnet 4

• Claude Opus 4

After June 15, 2026, all requests using these models will return an error. Existing modules in your scenario that use these models will fail when they run.

What do you need to do?

Review your Anthropic Claude modules and replace any deprecated models with a supported model.

Deprecated model	Replacement model
Claude Sonnet 4	Claude Sonnet 4.6
Claude Opus 4	Claude Opus 4.6

Review Anthropic's model pricing documentation for these replacement models, as your costs may change depending on your usage.
