v0 by Vercel vs Vercel

v0 ships at very high cadence, mixing small daily fixes with substantive agent-capability work. The May releases gave the agent the ability to run terminal commands (with per-command permission prompts), cut sandbox startup time by 50%, added OAuth-authorized MCP server support in the platform API, and made Claude Opus 4.7 Fast a configurable model option. Surrounding work — Snowflake account picker, browser screenshots in previews, .riv file support, design-mode element screenshots — pushes v0 further into 'real builds, not just UI prototypes.'

v0 is moving from AI-assisted UI generation toward an AI coding agent that owns the full build-and-deploy loop. Terminal access, faster sandboxes, OAuth MCP, and tight Vercel/Snowflake integrations are platform plumbing for production work, not prototyping. Model coverage stays at the cutting edge — Opus 4.7 Fast landed as a selectable model the same week it was announced — and the bug-fix discipline shows a team treating v0 as a maintained engineering tool, not a demo surface.

Next likely move is longer-running or background agent work — scheduled runs, async tasks, or an agent that owns a Vercel project across days. The combination of terminal execution + sandbox speed + MCP is the foundation; what's missing is persistence.
