Claude Opus 4.7 Is Here — What the xhigh Reasoning Tier Actually Changes for Vibe Coders

Anthropic released Claude Opus 4.7 today, and the headline numbers are real: 80.8% on SWE-bench Verified (up from 72.3% in 4.6), a new 'xhigh' reasoning effort tier, enhanced vision to 2,576px, and built-in cyber safeguards — all at the same pricing as Opus 4.6 ($5/$25 per million tokens). For vibe coders, the benchmark numbers matter less than the workflow implications. This post breaks down what actually changes for people who build things with Claude every day.
