I "hired" an AI employee, and a few things surprised me.
Costs can surpass a VA fast
Especially if you're not disciplined about it. Agents are hungry for tokens and smart models. The bill adds up quicker than you'd expect, and if you're running the agent on a capable model without guardrails on context length or invocation frequency, you can blow past what a virtual assistant would cost in a week.
Onboarding takes just as long as with a person
Agents spin their wheels and waste time on made-up tasks if you don't have extremely clear instructions and standards. I spent a lot of time building prompts, frameworks, and SOPs that actually work. The idea that you can just point an agent at your business and walk away is fantasy.
I didn't know my business as well as I thought
This was the real surprise. Employing agents requires radical clarity. Your processes have to be so clear that a machine can execute them. Turns out, most of us don't write things down that precisely. We rely on tacit knowledge, gut calls, and "you'll figure it out" — and that works with people because people fill in the gaps. Agents don't.
Most models aren't good enough
The ones that work cost more. The cheaper or local models got confused easily and frequently neglected critical steps. There's a meaningful quality cliff between the top-tier models and everything below them, and that cliff matters a lot more when the model is operating autonomously.
The win
My employee never sleeps and follows my instructions well. Once the standards are locked in, it handles async work while I focus on decisions and strategy.
But "set it and forget it" is a lie. It needs continuous refinement and a lot of tokens.
The bottom line
If you're thinking about investing in an AI employee, the AI is the easy part. Just like hiring a person, understanding your business is what really matters.
