SAN FRANCISCO, CA – Developers can now seamlessly integrate OpenAI's newly released GPT-5 model into their applications with minimal effort, thanks to the Vercel AI SDK and AI Gateway. Guillermo Rauch, CEO of Vercel, highlighted this ease of transition, stating that users of the @aisdk and AI Gateway can switch to 'openai/gpt-5' by replacing a single string, requiring no additional sign-up. This development underscores the rapid evolution and low switching costs prevalent in the artificial intelligence industry.
The release of GPT-5 on August 7, 2025, marks a significant advancement in large language models, offering enhanced reasoning, reduced hallucinations, and improved capabilities in coding and complex problem-solving. OpenAI has positioned GPT-5 as a unified system, integrating its most advanced reasoning and multimodal features. This new model is now available to both free and paid ChatGPT users, with enterprise and educational customers gaining access shortly after.
Vercel's AI SDK, an open-source TypeScript library, provides a streamlined toolkit for building AI-powered applications across various frameworks like Next.js, React, Svelte, and Vue. Complementing this, the AI Gateway acts as a provider-agnostic layer, managing API keys, rate limits, and offering performance optimizations. This combination allows developers to switch between approximately 100 AI models without complex infrastructure changes.
Rauch emphasized the unprecedented speed of the AI industry and the remarkably low switching costs. In his tweet, he noted, > "As an aside, I don’t think I’ve ever seen an industry that moves this fast, with the switching costs this low. The best intelligence wins." This sentiment reflects a market where rapid innovation and developer-friendly tools are crucial for widespread adoption and competitive advantage.
The integration capabilities of the AI SDK and AI Gateway are designed to accelerate product development, allowing teams to focus on creating value rather than managing complex AI infrastructure. This approach supports the swift adoption of cutting-edge models like GPT-5, fostering an environment where developers can quickly leverage the latest AI advancements.
