// "YES"
console.log(text)xsAI uses a variety of methods to make itself smaller.
It's just a wrapper for Fetch API, ESM Only, adding additional dependencies only when absolutely necessary.
How xsAI small? you can try install it with pkg-size.dev:
[email protected] is 111KB install size and 11KB bundle size (3KB gzipped).
Notably, this contains dependencies introduced to support tool calls and structured output.
If you only need the basic generateText, @xsai/[email protected] is only 12KB install size and 1.2KB bundle size (678B gzipped). (try install it with pkg-size.dev)
xsAI doesn't depend on Node.js Built-in Modules, it works well in Browsers, Deno, Bun and even the Edge Runtime.
You can also install only some of the utils of xsAI, such as
