DEFAULT — Claude Sonnet 5 is now the default model for Free and Pro users worldwide. It's the most agentic Sonnet yet and performs close to Opus 4.8 on many tasksPRICE — Sonnet 5 launch pricing ($2 in / $10 out per million tokens) runs through August 31, then returns to $3 / $15. Worth measuring your real token costs nowFASTEND — Fast mode for Claude Opus 4.7 is removed on July 24 — three days left. If you set speed: 'fast', move those calls to fast mode on Opus 4.8MEMORY — Claude's memory now works as a set of individual, categorized entries that Claude reads and updates mid-conversation, so it's easier to see what's storedHIPAA — Enterprise and API organizations can now configure HIPAA support themselves: BAA review, guide download, and one-step enablementADMIN — The Admin API can list members, change roles, remove people, and manage groups — helpful for organizations with frequent membership changesDEFAULT — Claude Sonnet 5 is now the default model for Free and Pro users worldwide.
