What's new on the Claude Platform — April 14, 2026

One bullet, but it's a calendar-entry kind of bullet: Anthropic announced deprecation of Claude Sonnet 4 (claude-sonnet-4-20250514) and Claude Opus 4 (claude-opus-4-20250514), with retirement on the Claude API scheduled for June 15, 2026. Migrate to claude-sonnet-4-6 and claude-opus-4-7 respectively — and note that Opus 4.7 ships with API breaking changes versus Opus 4.6.

Sonnet 4 and Opus 4 deprecation — retirement June 15, 2026

Why: Both models are reaching end-of-life on the Claude API; without migration, requests to the deprecated model IDs will return errors after June 15, 2026.

What: Anthropic announced deprecation of claude-sonnet-4-20250514 and claude-opus-4-20250514, with retirement scheduled for June 15, 2026.

How: Migrate to claude-sonnet-4-6 and claude-opus-4-7 respectively before June 15, 2026. For Opus, read the dedicated migration guide because Opus 4.7 includes API breaking changes versus Opus 4.6.
