The problem
Claude Projects and ChatGPT Projects are useful, but they have a ceiling. Every session starts fresh unless you manually reload context. Claude Projects with a loaded .md file works, but you maintain that file manually. Hermes maintains its own memory autonomously. For a single question that is fine. For an assistant that handles recurring operational tasks across days and weeks, it means you spend time re-explaining the same things instead of just getting work done.
The other issue is availability. Managed tools run on someone else's schedule. Rate limits, outages, and interface changes are outside your control. If the assistant is part of your daily operations, that dependency matters.
Hermes Agent is open source, MIT licensed, and runs on any VPS from about $5 per month.
What Hermes actually is
Hermes Agent is an open-source autonomous AI agent built by Nous Research. It is not a chatbot wrapper and not a simple Telegram bot. It is a long-running process that lives on your server, remembers what it learns, runs tasks on a schedule, and gets more capable the longer you use it.
The key difference from Claude Projects or ChatGPT Projects: Hermes maintains its own memory autonomously. After you give it your business context once, it carries that forward across every session. You do not re-explain who you are, what you build, or what your stack looks like every time you open a chat.
Hermes writes structured memories after each session. Next time you start, it already knows your business, your tools, your clients, and your preferences.
After completing a complex task, Hermes writes a reusable skill so it can handle the same task faster next time. The longer it runs, the more capable it becomes at your specific workflows.
Cron-based task runner built in. Set a morning digest, a weekly report, or a daily status check. It runs without any trigger from you.
Web search, browser automation, file operations, code execution, image generation, and cross-platform messaging can be enabled during setup. Keep the Telegram toolset as small as the actual job allows.
Hermes supports Anthropic, OpenAI, Google Gemini, DeepSeek, OpenRouter, Nous Portal, local endpoints, and other compatible providers. The model can change without reinstalling the agent.
Hermes stores its sessions, memory, and skills on your server and does not add its own telemetry. Prompts and relevant tool context still go to the LLM provider you configure unless you use a local model.
The setup
Installation runs through a single curl command. The installer auto-detects dependencies, installs Python 3.11 and supporting tools if they are missing, and walks through provider selection, platform configuration, and tool enablement via interactive menus.
Lock Telegram down before enabling server tools
The setup wizard asks for a numeric Telegram user ID. That value is the sender allowlist, and it is different from a chat or group allowlist. In current Hermes configuration, the important setting for a private bot is TELEGRAM_ALLOWED_USERS or its allow_from equivalent in the active profile.
TELEGRAM_ALLOWED_USERS=123456789
Use your own numeric ID from /whoami or @userinfobot, never the placeholder above. An empty allowed_chats field by itself does not prove that the bot is open because it controls a different scope. Verify the effective sender allowlist instead: it should contain your ID, no wildcard, and no group IDs unless group access is intentional.
TELEGRAM_ALLOWED_USERS, with no wildcard, guest mode, group allowlist, profile override, or systemd override. Its empty allowed_chats value therefore does not let other Telegram users control Hermes. It only means the approved sender can reach the bot from any chat the bot has joined. Keep sensitive commands in the private DM because replies sent in a group remain visible to that group.
- Back up
~/.hermes/.envandconfig.yamlbefore changing gateway access. - Keep the bot token and API keys out of screenshots, logs, shell history, and Git.
- Restart the gateway after an allowlist change, then confirm the active profile and effective authorization mode.
- Review gateway logs for unexpected sender or chat IDs. Rotate the bot token through BotFather if exposure is suspected.
NOPASSWD: ALL sudo. Hermes documentation recommends passwordless sudo only for specific commands when messaging access genuinely needs it. A safer production layout runs the Telegram gateway as a dedicated non-root user or uses a sandboxed terminal backend, while full administration stays in an authenticated SSH or local CLI session.
The live setup in this case was rechecked on Hermes Agent v0.18.2 on July 18, 2026. The official Telegram configuration guide documents TELEGRAM_ALLOWED_USERS, and the Hermes security and troubleshooting guide explains the safer sudo pattern.
What it does in practice
After setup, Hermes is reachable on Telegram. The first interaction is straightforward: send it your business context and it saves it to persistent memory.
What did not work
DeepSeek was the first provider selected because of the low cost. It failed immediately with a provider error on every message. The gateway logs showed the API was returning empty responses. The actual reason turned out to be simple: the DeepSeek account balance was below $0.01, not enough to process even a test request.
The current deployment now uses deepseek-v4-pro through the direct DeepSeek API. With provider deepseek, the clean model identifier is deepseek-v4-pro; repeating the provider prefix as deepseek/deepseek-v4-pro can trigger a configuration warning even when requests still work.
Two other things worth knowing before setup:
- The full setup wizard can loop back to the beginning if you navigate past the last step. There is no need to run through it again. Ctrl+C after the first pass exits cleanly and the configuration is already saved.
- A
uv.lockwarning appears during installation on some Ubuntu versions. It is not critical. The installer falls back automatically and everything continues.
Cost
Free. MIT license, no subscription, no per-seat fee.
About $5-7 per month on Contabo or a comparable provider. The same server can run n8n alongside Hermes without conflict.
DeepSeek V4 Pro is usage-based. On July 18, 2026, the official direct API price was $0.003625 per million cached input tokens, $0.435 per million uncached input tokens, and $0.87 per million output tokens. Actual monthly cost depends on context size, tool output, and usage. Prices may change.
If you are still deciding whether an AI agent is the right fit for your situation, the AI agents for business guide covers the difference between chatbots, automation workflows, and agents, and when each one makes sense.
When this makes sense vs Claude Projects
You want the assistant to remember your business context permanently, run scheduled tasks automatically, stay available 24/7 on your own infrastructure, and work through Telegram without opening a browser.
You need a capable reasoning assistant for occasional deep work, research, or writing tasks. Claude Projects is faster to start, requires no server, and is better suited for tasks where raw model quality matters more than persistence.
Hermes handles daily operations and scheduled tasks through Telegram. Claude Projects handles heavier analysis and writing work in the browser. They cover different parts of the workflow and do not overlap.
