Anthropic shipped Claude Opus 4.7 today.
Everyone's posting benchmarks. Here's what they're missing:
The model got so much better at following instructions that your old prompts break.
Your prompt library just became technical debt.
Every model upgrade is a re-tuning tax. The people who'll thrive aren't the ones with the biggest prompt libraries — they're the ones who treat prompts like code.
Versioned. Tested. Refactored when the runtime changes.
