An open-source, provider-agnostic Rust library for building AI-powered applications, inspired by the Vercel AI SDK and designed with Rust’s safety, performance, and ergonomics in mind.

Docs: aisdk.rs
GitHub: https://github.com/lazy-hq/aisdk

Feature Highlights

• Agents & Tools
• Strong model-level type safety
  • Ensures at compile time that the chosen model supports the task. (tools, structured output, reasoning).
  • This Prevents using incompatible models (e.g. a non-reasoning model for a reasoning task).
• Structured outputs
• Text generation & streaming
• Idiomatic Rust API

Frontend-friendly by design

Fully compatible with Vercel’s AI-SDK UI, so it works seamlessly with:

• Next.js
• Solid.js
• Svelte and more

The project is open-source and actively evolving.

We’d love feedback from the community, issues, PRs, and suggestions are all welcome!
