How much does it cost to run Hermes Agent each month?

Hermes Agent is free and open source. What you pay each month is the computer it runs on plus the model it uses. On Vavio, $14.99 a month gives your Hermes its own managed computer, with the same price at renewal and no setup fee. The model provider you choose for Hermes bills its usage separately. If you also connect an AI you already pay for, such as ChatGPT or Claude, to help manage your Hermes, that plan stays as it is.

Your monthly Hermes budget in three lines

Most of a Hermes budget is decided by two choices: where Hermes runs and which model it uses. The third line is optional.

Cost	Who bills you	What changes it	New cost or existing one?
The computer that runs Hermes	Vavio: $14.99 a month, billed monthly in advance	Nothing in normal use. The price is the same at renewal, with no setup fee and no annual commitment.	New: this is what hosting adds.
The model Hermes uses	The model provider you connect to Hermes	Your plan’s price and limits, or how much work Hermes does on a pay-per-use key	Depends on the provider. Some people use a plan they already have.
The AI you use to manage Hermes (optional)	That AI’s own provider	Its own plan and limits	Usually existing. You can also manage everything on the Vavio website.

The hosting line is fixed. The model line is the one that moves, so it is the one to watch.

A worked example

Suppose your model provider bills you $5.00 for a month. The $5.00 is only there to show the arithmetic. It is not a model price or a usage forecast.

$14.99 for hosting + $5.00 of model usage = $19.99 for the month, before any applicable taxes and before any assistant plan you pay for separately.

To work out your own total, take $14.99 and add the month’s figure from your model provider’s usage or billing page. Hosting fees exclude taxes unless stated otherwise, as set out in the Vavio Terms of Service.

What decides the model bill

The model bill depends on how your provider charges. Hermes needs at least one model provider. Nous Research’s provider guide describes three broad ways to pay:

• Sign in with a subscription. The guide lists sign-ins for plans such as Nous Portal, a ChatGPT or Codex subscription, Claude Max and SuperGrok. You pay the plan’s monthly price, and Hermes’s work counts against that plan’s limits. Check your plan’s terms for using it with Hermes.
• Use a pay-per-use API key. Providers such as OpenRouter, the OpenAI API, the Anthropic API, Google Gemini and DeepSeek bill for what Hermes actually sends and receives. Larger models, longer tasks and scheduled jobs cost more.
• Point Hermes at a model you run yourself. A self-hosted endpoint such as Ollama or vLLM has no per-use bill from a provider. Instead, you supply and pay for hardware that can run the model.

A hosted Hermes keeps running when your laptop is closed. That is the point of hosting it, but it also means scheduled jobs and messages can keep using the model while you are away. If your provider offers a spending limit or prepaid credit, set one before you leave Hermes working unattended. Rates change, so check your provider’s current pricing page on the day you choose.

What the hosting price covers

The $14.99 covers the computer and its management. Model usage is not included.

Included in Hermes hosting:

• Your own Hermes computer in Europe, with 8 GB memory and 100 GB SSD storage.
• Hermes Agent set up for you, on a server Vavio looks after.
• Vavio’s MCP server and CLI, so your own AI can check your setup, guide the next step and help manage your Hermes.

Not included:

• Model usage, which the provider you choose bills.
• The plan of the AI you connect to manage Vavio.
• Backups. They aren’t included yet, so keep your own copies of anything important.
• An uptime or recovery-time promise. Model limits, approvals, maintenance and errors can still interrupt a task.

You can cancel in Billing at any time. Your hosting then runs to the end of the month you’ve paid for.

When running Hermes yourself makes more sense

Install Hermes yourself if you already have a computer that stays on, or you want to try Hermes before paying for hosting. Nous Research publishes desktop packages and a one-line installer for Linux, macOS and WSL2 in its installation guide. On your own machine the monthly cost is the model plus the machine’s own running costs. You also take on installing, updating and securing it, and Hermes only runs while that machine does.

Hosting changes who does that work. Your Hermes gets its own computer that doesn’t depend on your laptop being open. Vavio sets Hermes up and looks after the server. You can ask the AI you already use to check on your Hermes through Vavio’s MCP server or CLI. In Vavio’s own production test on 7 November 2026, run with a test discount, Codex bought the hosting and the computer was ready in about 15 minutes. A model was then connected in a separate step, and Hermes replied to a message.
