Frequently Asked Questions about Hermes Agent

Can I run Hermes Agent on a cheap VPS, or does it need expensive infrastructure?

Hermes Agent runs on a $5 VPS without issue, since it's designed for minimal resource consumption. It also supports serverless deployment, so you only pay for compute when the agent is actually working and costs nearly nothing while idle.

How does the persistent memory work across sessions?

Hermes Agent uses FTS5 full-text search combined with LLM summarization to recall information from past conversations and projects. This means it learns your preferences and context over time and never forces you to repeat yourself, unlike stateless chatbots.

What happens when Hermes Agent creates a new skill?

Skills are portable and can be shared on agentskills.io, the community hub for agent skills. This means improvements the agent makes to its own capabilities are not locked to your instance and can benefit other Hermes users.

Can I connect Hermes Agent to my Slack workspace?

Yes, Hermes Agent integrates with Slack, Discord, Telegram, and WhatsApp through a single messaging gateway. This lets your team collaborate with the agent directly in your existing chat platforms, or gives you personal access from any device.
