faq:
  - question: "How much does Hermes Agent cost?"
    answer: "Hermes Agent is open source and free to install. Your cost is entirely the model API behind it. A developer using Hermes as a daily assistant with MiniMax M2.5 spends roughly $5–$15/month. The same usage on Claude Sonnet 4.6 runs $50–$200/month. Heavy autonomous workloads on GPT-5.4 or Opus 4.6 can reach $500–$1,500/month."
  - question: "Is Hermes Agent free?"
    answer: "Yes — the Hermes Agent software from Nous Research is free and open source. There's no subscription, seat fee, or per-run charge from Hermes itself. You only pay the underlying model provider for the tokens your agent runs use."
  - question: "What's the cheapest way to run Hermes Agent?"
    answer: "The cheapest paid path is MiniMax M2.5 at about $0.12/M input and $1/M output, or DeepSeek V3.2 at roughly $0.27/M. The cheapest path overall is a local model via Ollama (Gemma 4, Qwen3.5), which costs $0 per token once you own the hardware. Routing most traffic to a budget model and only escalating to a flagship when needed cuts a typical bill by 60–90%."
  - question: "Can I use a Claude Max or ChatGPT Plus subscription with Hermes Agent?"
    answer: "No. Hermes connects over API endpoints, not consumer chat subscriptions. A Claude Max or ChatGPT Plus plan does not include API access, so you need a separate API key from Anthropic, OpenAI, or an aggregator like haimaker.ai. The upside: API billing is pay-as-you-go, so a light Hermes user often pays less than a $20/month chat subscription."

Hermes Agent from Nous Research is free. It's open source, there's no seat fee, and nobody charges you per run. So when people ask what Hermes "costs," they're really asking about the model behind it — and that bill ranges from a few dollars a month to four figures, depending on which model you point it at and how hard you work it.

## Hermes is free — you pay for the model

Install Hermes, configure a model endpoint, done. The bill that shows up is from whatever provider serves that endpoint — Anthropic, OpenAI, Google, MiniMax, DeepSeek, Z.ai, Moonshot, or an aggregator. Hermes itself takes no cut.

That also means there's no "Hermes plan" to choose. Your pricing decision is a model decision.

## Typical monthly bills by use case

Real ballparks, assuming normal usage patterns:

| Use case | What it looks like | Budget model (MiniMax M2.5) | Mid-tier (Claude Sonnet 4.6) | Flagship (GPT-5.4 / Opus 4.6) |
|---|---|---|---|---|
| **Light assistant** | A few message-driven tasks a day, some reminders and lookups | $2–$8 / mo | $20–$60 / mo | $80–$250 / mo |
| **Daily coding agent** | Regular multi-file edits, debugging, code review through the day | $8–$25 / mo | $50–$200 / mo | $300–$900 / mo |
| **Heavy autonomous** | Long overnight runs, monitoring, multi-step automations across platforms | $25–$80 / mo | $150–$500 / mo | $500–$1,500+ / mo |

The spread between columns is the whole story: the model you choose moves your bill by 10–50x for roughly the same work. That's why the rest of this guide is mostly about picking models, not about Hermes.

## Per-provider model pricing

Approximate API pricing per million tokens (input / output). Providers change these regularly — check current rates before you commit.

| Model | Input / Output | Notes |
|---|---|---|
| **MiniMax M2.5** | ~$0.12 / $1 | Cheapest model that still holds up in Hermes' tool loops |
| **DeepSeek V3.2** | ~$0.27 / M | Low-cost coding and reasoning fallback |
| **GLM-4.7 / GLM-5** | sub-dollar | Cheap general-purpose agent work |
| **Kimi K2.5** | cheap | Large context, good for long chats |
| **Gemini 3 Flash** | ~$0.075 / $0.30 | Very cheap, fast, fine for simple high-volume tasks |
| **Gemini 3.1 Pro** | ~$1.25 / $10 | 1M+ context for research and codebase Q&A |
| **Claude Sonnet 4.6** | $3 / $15 | The reliable default for autonomous loops |
| **Claude Opus 4.6** | ~$5 / $25 | Mission-critical work where errors are expensive |
| **GPT-5.4 Codex** | premium tier | Heavy multi-file coding |
| **Gemma 4 8B / Qwen3.5 (Ollama)** | $0 per token | Local — you pay for hardware and electricity, not tokens |

Through [haimaker.ai](https://haimaker.ai) the same models run about 5% below market rate on one API key, which also saves you from holding a separate billing account with each provider.

## Where the savings actually come from

Three levers, in order of impact:

1. **Route most traffic to a budget model.** Run MiniMax M2.5 or DeepSeek V3.2 as your Hermes default and only override to Sonnet, Opus, or a Codex model for tasks that genuinely need it. This one change is where 60–90% of a typical bill goes.
2. **Trim the context.** Hermes keeps tool outputs and file contents in the prompt. Don't load files the agent doesn't need, and prune long histories — every token in the window is a token you pay for on the next turn.
3. **Avoid output-heavy flagships for routine work.** Output tokens cost 5x input on Claude and more on the pro tiers. A chatty Opus run gets expensive fast; the same task on a cheaper model with similar quality on simple work costs a fraction.

## A note on subscriptions

Hermes does not work with a Claude Max, ChatGPT Plus, or Gemini Advanced consumer subscription — those are chat-app plans and don't include API access. You need an API key. The good news is API billing is pay-as-you-go: a light Hermes user often spends less per month than a $20 chat subscription would cost, because you only pay for the tokens you actually run.

## Set up haimaker.ai with Hermes Agent

If you'd rather not open billing accounts with five different model providers — and you want the cheapest routing per token — point Hermes at haimaker.ai once and switch models by changing a single string.

1. Create an account and get an API key at [app.haimaker.ai](https://app.haimaker.ai/sign-up). New accounts start with free credits, so you can test costs before committing.
2. In your terminal, run:

   ```bash
   hermes model
   ```

3. Choose **Custom endpoint**.
4. Enter the connection details:
   - **Base URL:** `https://api.haimaker.ai/v1`
   - **API key:** your haimaker.ai key
   - **Model:** start cheap with `minimax/minimax-m2-5` or `deepseek/deepseek-v3-2`; switch to `anthropic/claude-sonnet-4-6` or `openai/gpt-5-4-codex` for heavier work
5. Run `hermes`. To change models later — say, to drop your bill — run `hermes model` again and swap the model string; the key and base URL stay put.
