Verified agents with Stagehand

Product Name: Stagehand

Stagehand 3.3.0 is live.

Verified mode for improved agent identity. Sessions get a verifiable identity that helps on sites that gate bot traffic. Enable in your session params:

const stagehand = new Stagehand({
  env: "BROWSERBASE",
  browserbaseSessionCreateParams: {
    browserSettings: {
      verified: true,
    },
  },
});

Plus:

Adaptive thinking with Anthropic models. Claude CUA now scales the extended-thinking budget to match task complexity — faster on simple steps, deeper when it counts.
Agent usage in stagehand.metrics. agent.execute() calls now contribute to stagehand.metrics on API-backed sessions, so token counts and model calls land where you expect them.
Strict structured outputs. Supported model paths now use strict JSON schema enforcement, eliminating malformed responses on extract() and other structured calls.
Clearer file upload elements. File inputs are now explicit in the page snapshot, so agents can identify and drive upload flows reliably.
