Vercel collaborates with OpenAI for GPT-5 launch

Released on August 7, 2025, the GPT-5 family of models is now available through AI Gateway and is actively being used in production across platforms like v0.dev and Vercel's infrastructure. Following extensive testing, GPT-5 has demonstrated superior capabilities in frontend design, generating polished UIs with clean, composable code, and excelling in agent-based workflows with strong long-context reasoning. Vercel utilizes GPT-5 within its dashboard Agent and other areas, showcasing its code quality and frontend sensibilities. The smaller GPT-5 variants, mini and nano, are noted for their low-latency delivery and consistency in speed-sensitive tasks. Vercel has introduced two interactive environments: a model playground for testing GPT-5 and a new open-source vibe-coding platform that demonstrates real application generation from prompts. This platform, built with Vercel AI Cloud, allows users to clone, customize, and build applications, leveraging AI SDK, AI Gateway, Vercel Functions, and more, all while emphasizing speed, security, and extensibility. The open-source initiative aims to show the potential of AI models in software development, offering an edge-based stack that is both independent and integrable with existing applications.
