Frequently Asked Questions

How are AI agents different from chatbots?
Chatbots follow scripted rules and respond to one message at a time. AI agents reason, plan multi-step actions, use external tools, and work toward a goal with minimal human input. See our [full comparison](/blog/ai-agents-vs-chatbots/).
Are AI agents safe to use?
They can be, with proper guardrails. Best practices include least-privilege permissions, human-in-the-loop approvals for high-risk actions, and audit logging. Read our [AI agent security guide](/blog/ai-agent-security/) for details.
What can AI agents actually do in 2026?
AI agents can review code, schedule meetings, triage support tickets, manage deployments, and orchestrate multi-step workflows across tools. See [15 real examples](/blog/ai-agent-examples/) for inspiration.
Will AI agents replace human workers?
AI agents automate repetitive tasks, but they still need human oversight for judgment calls, creative decisions, and edge cases. Think of them as tireless teammates, not replacements.
How much do AI agents cost to run?
Costs depend on the LLM and usage. A lightweight agent on DeepSeek can cost ~$0.02 per session, while heavier enterprise setups run higher. See our [AI agent cost breakdown](/blog/ai-agent-cost/).
