Ai agents

AI agents and webhooks let attackers automate phishing end to end: personalized messages, AI-built fake login and crypto portals, real-time follow-ups, and campaigns at scale. Here is how it works and what defends against it.

A technical comparison of cloud computers for AI agents in 2026: machine0, OpenComputer, E2B, Daytona, Fly.io Sprites, Vercel Sandbox and Modal. Isolation, persistence, lifetime limits, GPUs, desktops and real per-hour prices, checked September 2026.

How AI agents control a computer in 2026: the screenshot-and-click loop, Claude and ChatGPT desktop computer use, a tested Python agent on Claude's computer_toolset_20260801, OpenAI's computer tool, open-source agents, and safe sandboxing.

Workers toggle between apps nearly 1,200 times a day and lose about 9% of their working year to it. Why teams are consolidating tool stacks into one AI workspace, and how to choose and pilot one in 2026.

The best computer use MCP servers in 2026, tested: Claude Code's built-in computer-use, Windows-MCP, Cua Driver, Peekaboo, Open Computer Use, macOS-MCP, computer-use-linux and computer-use-mcp, with install commands, tool counts, permissions, and how to reach a remote desktop over a Pinggy tunnel.

TypeSafe's Jev is a System One model that returns typed decisions instead of text: 70-500ms latency, $0.042 per million input tokens with output free, and 0% structured-output errors. Here are the three jobs it actually fits, the honest benchmark picture against GPT-6 Astra and Claude, and the tasks where it is the wrong tool.

How to install Nous Research's open-source Hermes Agent on your own machine and run it at zero token cost on OpenRouter free models - the tool-calling and 64K context requirements, the request limits that actually bite, a free-model fallback chain, and remote access over a tunnel.

Long-horizon agent runs fail for structural reasons, not intelligence reasons. Here is what actually holds a multi-hour agent workflow together: a written success contract, separated discovery and delivery phases, persistent state outside the context window, external test oracles, checkpoints, and hard limits on autonomy.

We pulled every company in YC's Summer 2026, Fall 2026, and Winter 2027 batches from the official directory and classified all 208 of them. Here are the real themes, the numbers behind them, and how they compare to YC's own Requests for Startups.

Cloudflare shipped Kitesurf, a browser engine written from scratch to run in V8 isolates on Workers instead of Chromium. Here's how it works, the real CPU and memory numbers, what it still can't do, and how to point it at an app running on your own machine.
