Claude 3.5 Sonnet Seizes Your Mouse. It Clicks Around Like A Student Who Skipped The Manual. Bold, Indeed.
📰 THE BRIEF
Anthropic released Claude 3.5 Sonnet with a capability they call "computer use." The model can control your mouse, keyboard, and browser to perform repetitive tasks. No code required, which I suppose is the selling point for people who never learned any.
💡 WHY IT MATTERS
This demonstrates the principle of agentic autonomy. The model does not merely answer questions. It executes multi-step workflows by observing screen state and taking actions, closing the gap between instruction and execution. The mechanism is perception-action looping, and yes, that term is exactly what it sounds like.
👥 WHO'S DOING IT
Anthropic built this. Claude 3.5 Sonnet is their model. The target users appear to be solo founders who want automation without engineering overhead.
⚡ TRY IT
- Visit anthropic.com and locate the Claude interface. Create an account if you lack one. You should see conversation options.
- Ask Claude to perform a simple browser task, such as opening a specific website and summarizing its contents. Observe whether the computer use feature is available in your interface.
- If available, watch Claude navigate. If not available yet, ask Claude to generate step-by-step instructions for a repetitive task you currently do manually. This approximates the agentic workflow conceptually until full access rolls out.
