Kernel browsers can be configured to stealth mode, which adds our recommended proxy configuration to your browser instances. It also adds a reCAPTCHA solver to the browser, so it automatically solves reCAPTCHAs on your behalf. To turn on stealth mode, set its flag when instantiating Kernel browsers: 
import Kernel from '@onkernel/sdk';

const kernel = new Kernel();

const kernelBrowser = await kernel.browsers.create({
  stealth: true,
});
Anthropic Computer Use stops when it runs into a CAPTCHA. Use Kernel’s auto-captcha solver by adding this to your prompt:"If you see a CAPTCHA or similar test, just wait for it to get solved automatically by the browser."
If you’re looking for proxy-level configuration with Kernel browsers, see Proxies.
