Wondering what the best model for Hermes agent is? Here's the honest answer up front: Hermes runs on almost any model — Grok, Claude, GPT, Gemini, free APIs, even a local model — so the "best" one really depends on what you want your agent to do. Below I'll break down the best model for Hermes agent for each job (speed, building, free, and quality), and show you how to switch models in a couple of commands.
Hermes itself is lightweight — it runs locally, even on a phone — and you just plug a "brain" into it. That's the whole trick.

The Best Model For Hermes Agent Depends On The Job
Most agent tools lock you into one model. Hermes doesn't care which AI you bring — as long as it has vision for computer-use tasks, you can run whatever you like and swap any time. So instead of one "best" model, think in terms of the best model for Hermes agent for each job:
Best Model For Hermes Agent Overall: Grok (xAI)
Right now my favourite pick is Grok. A recent update lets you plug Grok straight into Hermes with a single login, and it unlocks a stack of features in one go: real-time X (Twitter) search, image generation, video generation, and text-to-speech — all through one model. It's also genuinely fast to reply. And here's the kicker: if you already pay for X, there's no extra cost — you're just using the subscription you already have. Connecting Grok to Hermes is like giving your agent eyes, ears, a voice and a live feed at once.
Best For Building: Claude (and Claude Code)
When you need your agent to build something — a dashboard, a workflow, an SEO blog, real code — Claude is the one. It's the deep-thinking, building engine: full tool access, it writes and implements code, and it slots straight into the Agent OS. Tell it "build me an SEO blog" and it goes off and does it. For heavy creation tasks, Claude is the best model for Hermes agent.

Best Free Model For Hermes Agent
You do not need to pay anything to run Hermes well. In the Hermes model menu there's a free provider built in, and you can also use free models via OpenRouter — so you can run a capable agent for $0. If you'd rather keep everything on your own machine, Hermes also runs local models (including Ollama models), which is the best route if privacy or zero API cost matters most. For most beginners, starting on a free model is the smart move.
Best For Maximum Quality
If you want the highest-quality output and don't mind the cost, point Hermes at a frontier model like Opus 4.8. A great pattern is to mix them: a cheap or free model does the bulk work, and a frontier model handles the parts that need to be flawless. Hermes lets you switch per task, so you're never stuck paying frontier prices for simple jobs.

How To Change The Model In Hermes
Switching models is genuinely a few commands — no code, no manual API wiring:
- Update Hermes first — run the Hermes update so it understands the newest models and tools.
- Run
hermes modelin your terminal, pick your model (e.g. the Grok/xAI option) and log in on the page it opens. - Enable the tools you want with
hermes tools(for example, X search, image and video generation, text-to-speech).
That's it — and anything you set up in the terminal automatically syncs into the Agent OS, so the change shows up across your whole setup.
Get The Best Models Wired Into The Agent OS
Picking a model is step one. The real power comes when Hermes, Grok, Claude and OpenClaw all sit in one mission-control dashboard with shared memory — that's the Agent Operating System inside the AI Profit Boardroom. Every model you plug in already knows your business (via the Obsidian memory setup), and you get a studio for images, video and voice, an SEO agent, goal mode, the loop engine, four weekly coaching calls, and a 30-day roadmap. → Join the AI Profit Boardroom.
