Opus 5 in Claude Code is quietly routing to Opus 5.2 for some users

People are noticing:
• Cleaner, more detailed output
• Easier communication flow
• Started happening ~2 days ago

Same playbook Anthropic used when they stealth-routed users to Fable 5.1

If you're building with Claude API, check your logs. You might already be on the new version without knowing it
