Claude Opus 4.7 GA with breaking API changes vs 4.6 — migration required

AI Impact Summary

Claude Opus 4.7 GA introduces stronger capabilities for complex reasoning and agentic coding, but it ships with API-breaking changes relative to Opus 4.6. Engineering teams should plan a migration window that updates clients, endpoints, and payload schemas, and revalidates prompts and long-running reasoning tasks across existing workflows. Despite pricing staying at $5 / $25 per MTok, migration should be tested thoroughly to avoid regression in automated coding tasks and multi-step reasoning pipelines.
