Introduction

Vercel has recently introduced a set of tools designed to simplify the integration of AI into web applications. With their new AI SDK and Chat SDK, developers and founders have an opportunity to quickly build and scale AI-powered features that enhance user experiences. In this post, we provide an in-depth look at both SDKs, what they offer, and how they can be useful for your projects.

What is the AI SDK?

Vercel’s AI SDK is a TypeScript toolkit that streamlines the process of integrating AI capabilities into your web applications. Here’s what makes it stand out:

Unified API:
The AI SDK provides a consistent interface to interact with multiple AI providers such as OpenAI, Anthropic, and Google AI. This removes the complexity of dealing with different APIs.

Framework-Agnostic:
Whether you're using React, Next.js, Vue, or Svelte, the SDK is designed to work seamlessly with your preferred framework.

Streaming Support:
It enables token-by-token streaming, allowing you to deliver real-time responses for a more dynamic user experience.

Type Safety:
Built with TypeScript, the SDK helps ensure better code reliability and reduces common development errors.

Extensibility:
The SDK supports custom tools and middleware, which means you can tailor it to fit advanced and unique use cases.

Core Functions of the AI SDK

The toolkit provides several functions for common use cases:

generateText(): Generate text outputs from language models.

streamText(): Stream text generation responses in real time.

generateObject(): Create structured data based on prompts.

streamObject(): Stream structured data generation.

embed(): Create embeddings for a single value.

embedMany(): Generate embeddings for an array of values.

In addition to these functions, there are custom hooks like useChat(), useCompletion(), useObject(), and useAssistant() that enable the rapid development of user interfaces powered by AI.

What is the Chat SDK?

Building on the functionalities of the AI SDK, Vercel’s Chat SDK is an open-source chatbot template designed for developers who want to add AI-driven chat capabilities to their applications. Key highlights include:

Customizable Interfaces:
The Chat SDK provides a framework to build custom chat experiences. This flexibility allows you to create chatbots that suit the specific needs of your application—whether that’s customer support, interactive marketing, or community engagement.

Real-Time Messaging:
With support for streaming data, the Chat SDK can handle real-time conversations effectively, ensuring smooth, responsive interactions.

Developer-Friendly:
Comprehensive documentation, clear guidelines, and a codebase built around best practices make it easier to integrate and extend.

In-Browser Code Execution:
A unique feature is the ability to run code directly in the browser using technologies like WebAssembly (WASM) and Pyodide, which eliminates the need for a separate sandbox environment.

How Can This Help You?

For Founders

Rapid Prototyping:
The SDKs enable you to quickly prototype AI-powered features. Whether you're looking to test a new idea or build an MVP, these tools can significantly reduce development time.

Cost Efficiency:
By leveraging these open-source resources, startups can lower their initial development expenses while still offering advanced functionality in their products.

Scalability:
Built on Vercel's robust infrastructure, these SDKs are designed to support applications as they grow, ensuring that your solution can scale alongside your user base.

For Developers

Simplified Integration:
The unified API and framework-agnostic approach mean that you can integrate cutting-edge AI functionalities into your projects without having to grapple with diverse APIs and complex setups.

Advanced Features Out-of-the-Box:
With support for streaming responses, text and object generation, and real-time data handling, you have access to advanced features that can enhance the interactivity and responsiveness of your applications.

Comprehensive Documentation and Community Support:
Vercel’s dedication to developer experience extends to thorough documentation and an active community. This makes troubleshooting and customization more manageable, providing valuable support as you build.

Conclusion

Vercel’s AI SDK and Chat SDK offer powerful, flexible solutions for anyone looking to infuse AI capabilities into web applications. Whether you’re a founder aiming to quickly validate a business idea or a developer looking to create seamless, real-time experiences, these tools provide a robust foundation.
