Facio's Spawn System: How Parallel Sub-Agents Multiply Agent Throughput

Gartner predicts 40% of agentic AI projects will be cancelled by 2027 due to escalating costs. One reason: most agent platforms run tasks sequentially. Facio's spawn system lets agents delegate work to parallel sub-agents — each with isolated context, optional model overrides, and direct filesystem access — and collect results asynchronously. Here's how the architecture works and when to use it.

Closing the Loop: How Human Feedback Turns Your HITL System Into an Agent Learning Engine

Every human approve, modify, or reject decision in your HITL pipeline is a labeled training data point. Most teams treat HITL as a safety mechanism and miss its bigger value: a continuous learning engine that makes agents smarter with every human interaction.

Facio's Built-in Browser: How AI Agents Navigate the Web Without External Infrastructure

Most AI agent platforms require a separate Playwright container, a CDP proxy, or a third-party browser service just to visit a webpage. Facio ships with a full browser automation suite built into the runtime — persistent sessions, accessibility snapshots, screenshots, and HITL gating. Here's how the architecture works and why it matters for production agent workflows.
