Key Takeaways
- A $10/month VPS is sufficient to run a persistent, capable personal AI — the cost barrier to 24/7 agent availability is lower than most people assume.
- OpenRouter as a provider router means you can access Claude Opus without maintaining a direct Anthropic subscription.
- Persistent memory across sessions means the agent remembers preferences and solutions without being re-briefed.
The Setup
Hetzner VPS at $10/month. Claude Opus 4.7 accessed via OpenRouter for model flexibility without direct provider lock-in. Hermes running as a persistent process, accessible via Telegram, Discord, Slack, and WhatsApp simultaneously.
“lives on a server with persistent memory”
Why VPS Over Local
Running locally means the agent is only available when your machine is on. A VPS means 24/7 availability — the agent can run scheduled tasks, answer messages at midnight, and maintain session state without depending on a laptop being open.
The $10/month cost is less than most people spend on a single SaaS tool that does far less.
What Persistent Memory Changes
Without persistent memory, every session starts cold — you re-explain preferences, re-establish context, re-describe how you like outputs formatted. With Hermes's MEMORY.md and USER.md, these preferences persist indefinitely. The agent remembers your preferred models, your working style, solutions to past problems, and project context.
- Preferred models and providers
- Working style and output format preferences
- Solutions to recurring problems
- Project context across multiple active workstreams
