smpandyaon For Computer Use, the harness matters as much as the model

Are there results comparing agents running different tools (agent-browser, playwright MCP, browse CLI), or is this mostly Stagehand focused?

smpandyaon We made Playwright 2x faster and 80% more token efficient

I tried this myself - my conclusion was the overhead of parsing a screenshot, generating an action, and being limited to headful mode is much less efficient than reading accessibility trees & generating CDP commands.

basically, browser automation is a closer-to-the-metal abstraction than computer use, allows more flexibility, and ends up being much cheaper at scale!

Why build with email now? Isn’t the world moving towards voice / live-chat paradigms?
