Build 10x products in minutes by chatting with AI - beyond just a prototype.
Ship that idea single-handedly todayArtificial Intelligence is now deeply woven into how we build applications and solve problems. Whether you’re an indie developer creating a next-gen chatbot, or a marketer generating content using AI, choosing the right tool is essential. Two powerful AI options—Vercel AI and ChatGPT—have emerged as top contenders in their respective domains.
But they serve very different purposes.
In this blog, we compare Vercel AI and ChatGPT, highlight their key differences, and help you decide which one is best for your use case. For example, ChatGPT can be used in a chatbot setup to provide real-time customer support and enhance user interaction.
AI models are the backbone of artificial intelligence, enabling machines to learn, reason, and interact with humans. In the context of chatbots, AI models are used to generate human-like responses to user input. The default chat model used in many chatbot templates is xAI grok-2-1212, but users can switch LLM providers with just a few lines of code. Other model providers, such as OpenAI, Anthropic, and Cohere, offer a range of AI models that can be integrated into chatbot applications. When building a chatbot, it’s essential to consider the type of AI model that best suits your project’s needs, taking into account factors such as performance, accuracy, and scalability.
Vercel is a frontend cloud platform known for building and deploying high-performance websites and applications. In 2023, it introduced the Vercel AI SDK, a toolkit to seamlessly integrate large language models (LLMs) like OpenAI’s GPT, Anthropic’s Claude, or Hugging Face models into your Next.js or React-based applications. Comprehensive documentation is available to help users navigate Vercel AI effectively.
ChatGPT, developed by OpenAI, is a generative AI chatbot that uses state-of-the-art language models like GPT-3.5 and GPT-4 Turbo. It is widely used for answering questions, writing content, generating code, brainstorming, and more. Pro users also benefit from a chat history feature, which allows them to view their previous interactions in a left-hand pane, enhancing the user experience by providing easy access to past conversations and promoting better context management in ongoing conversations.
| Factor | Vercel AI | ChatGPT |
|---|---|---|
| Product Type | Developer SDK for AI integration | Full-featured conversational chatbot |
| Customization | High – build your own UI and logic | Low – limited to prompts and basic settings |
| Interface | Developer-centric (React/Next.js) | User-facing GUI |
| Flexibility | Supports multiple LLM providers | Tied to OpenAI’s models only |
| Scalability | Cloud-ready, optimized for production | Limited scalability for production use |
| Pricing | Depends on model usage + hosting | Free / $20 per month (ChatGPT Plus) |
| Analytics | Advanced analytics integration for monitoring user behavior and optimizing performance | Basic analytics capabilities |
The AI SDK is a powerful tool for building and managing chatbot applications. It provides a flexible way to integrate different AI models into your application, allowing you to switch LLM providers and customize your chatbot’s functionality. With the AI SDK, you can create a dynamic chatbot that can understand and respond to user input in a human-like way. The SDK also provides features such as server-side rendering, advanced routing, and efficient file storage, making it an ideal choice for building powerful chatbot applications. To get started with the AI SDK, you can install the Vercel CLI and create a new project using the `vercel` command.
From there, you can use the SDK to build and deploy your chatbot application, taking advantage of seamless navigation, structured objects, and component primitives.

Security and privacy are critical considerations when building and deploying chatbot applications. To ensure secure authentication, it’s essential to use a secure authentication model that protects user data and prevents unauthorized access. When using the AI SDK, you can take advantage of features such as environment variables and secure storage to protect sensitive information. It’s also important to consider the potential risks of exposing secrets, such as API keys or authentication credentials, and to take steps to prevent this from happening. By using a secure authentication model and following best practices for security and privacy, you can build a chatbot application that is both powerful and secure, providing a safe and reliable experience for your users. Additionally, you can use Vercel’s built-in security features, such as automated threat detection and proactive vulnerability management, to further protect your application and ensure the integrity of your users’ data.
