The Gemini 3 Pro Preview model, released today, is now available through the Vercel AI Gateway and on v0.app. Thanks to Google, Vercel has been testing Gemini 3 Pro Preview across v0, Next.js, AI SDK, and Vercel Sandbox over the past several weeks.
We've noticed the model has an increased focus on coding, multimodal reasoning, and tool use, though it's seen improvements across the board.
From our testing, Gemini 3 Pro Preview delivers substantial improvements in instruction following and response consistency. It shows almost a 17% increase in correctness over its predecessor on our Next.js evals, putting in the top 2 models on the leaderboard.
