Vercel AI SDK Development

Professional Vercel AI SDK development from experienced developers based in Graz, Austria.

The Vercel AI SDK is a TypeScript toolkit for integrating AI functionality into web applications. It abstracts the differences between LLM providers such as Azure OpenAI, OpenAI, Anthropic and Ollama behind a unified API and is built streaming-first — responses are delivered token by token to the UI instead of making users wait for a complete answer.

At dectria, we use the Vercel AI SDK in production in NetCero, our ESG/GHG reporting platform. It powers real-time report generation, text summarization, tone adjustment and multi-language content generation. The streamText() function is integrated directly into our rich text editor, so AI-generated content flows live into the document.

The key advantage is provider abstraction: we can switch between Azure OpenAI for production and Ollama for local development without changing a single line of application logic. This eliminates vendor lock-in, enables flexible pricing and gives our clients the freedom to choose their preferred AI provider.

Use Cases

Typical Use Cases

AI-Powered Text Generation in SaaS Products

Real-time creation of reports, summaries and structured text directly within the application — as used in NetCero for ESG reports with live streaming into the editor.

Intelligent Assistance Systems

Context-aware AI assistants that answer user questions, interpret data and generate recommendations — with the flexibility to choose the optimal LLM provider per use case.

Multi-Provider AI Architectures

Applications that leverage multiple AI providers in parallel — such as Azure OpenAI for production workloads, Ollama for privacy-sensitive on-premise scenarios and Anthropic for complex reasoning tasks.

FAQ

Vercel AI SDK FAQ

Why does dectria use the Vercel AI SDK instead of calling OpenAI APIs directly?
The Vercel AI SDK provides a unified abstraction layer across all LLM providers. Instead of maintaining separate integrations for each provider, we write the logic once and switch providers via configuration. This saves development time, avoids vendor lock-in and allows us to flexibly switch between different LLM providers.
Does the Vercel AI SDK work with self-hosted models?
Yes, through the Ollama provider the Vercel AI SDK supports locally hosted open-source models. We use this capability at dectria for local development and for clients who cannot use cloud-based AI services for data privacy reasons. The same application runs with Azure OpenAI in the cloud and with Ollama on-premise.
Can dectria integrate the Vercel AI SDK into existing applications?
Absolutely. The SDK can be incrementally integrated into existing Next.js and Node.js applications. We typically start with a single AI feature — such as text summarization or a chatbot — and then expand the integration as needed. The streaming support ensures an excellent user experience from the start.
