v0 adds Claude Opus 4.7 Fast support for 2.5x faster UI generation

Vercel has integrated the new Claude Opus 4.7 Fast model into v0, providing a significant boost to generation speed and reasoning capabilities. This update allows v0 to handle complex multi-file project requests with much lower latency than previous versions.

Why it matters: Builders will spend less time waiting for code to stream, allowing for a much faster 'vibe-coding' iteration cycle when building complex dashboards or apps.
