Hermes Agent runs on whatever model you point it at, and several of those cost nothing. One of them does not even need an account. Here are the genuinely free routes in 2026, what each is good for, and where the catch is.
1. OpenCode Free — Keyless, No Account
This is the one most people miss. Hermes ships an opencode-free provider that talks to OpenCode's Zen relay, and it is keyless by design — the relay serves free-tier models anonymously, so the provider deliberately sends no credential at all. No signup, no API key, no billing page.
Setting it up is one command:
hermes model
# or, from inside a chat
/model freeThe default lightweight model here is laguna-s-2.1-free, chosen because it is the fastest free model on the relay that is not user-agent gated. Other free models on the relay are rate-limited more aggressively, so expect occasional 429s if you push hard.
Best for: trying Hermes in the first five minutes, or a low-volume personal bot where an occasional retry is fine.
2. Ollama or llama.cpp — Free Forever, On Your Hardware
Running the model yourself is the only option with no quota, no rate limit and no third party seeing your prompts. Hermes treats both as a custom OpenAI-compatible endpoint, and declares convenient aliases — ollama, llamacpp, llama.cpp, vllm and local all resolve to it.
# config.yaml
model:
provider: llamacpp
default: qwen2.5-7b-instruct
base_url: http://localhost:8080/v1A 7B model quantized to Q4_K_M needs roughly 6 GB of RAM and runs on a laptop CPU or Apple Silicon. The tradeoff is real: small local models are noticeably weaker at multi-step tool calling than a frontier model, and agent work leans on exactly that.
Best for: privacy-sensitive work, offline use, and high-volume tasks where per-token pricing would hurt.
3. OpenRouter Free Models
OpenRouter aggregates dozens of providers behind one API, and a rotating set of models carry a :free suffix. Hermes has a first-class openrouter provider, so this is a config change rather than an integration.
The free pool changes regularly and free requests are rate-limited and deprioritized against paid traffic. Treat any specific free model as temporary — check the current list rather than pinning one and expecting it to last.
Best for: sampling many models cheaply before committing to one.
4. Google Gemini Free Tier
Google offers a free tier on the Gemini API, and Hermes ships a gemini provider. You need a Google account and an API key, but no card for the free tier. Quotas and eligible models change often enough that the only reliable source is Google's current pricing page.
Best for: multimodal work — image understanding in particular — where local models struggle.
5. Hugging Face and NVIDIA NIM
Hermes ships providers for both huggingface and nvidia. Each offers a free allowance for open-weight models, both need a free account and an API key, and both are metered. They are worth knowing about mainly because they widen the range of open models you can try without running the weights yourself.
Best for: testing a specific open-weight model you cannot fit locally.
6. A Free Trial on Managed Hosting
If the point is to see whether an always-on agent is useful before investing a weekend in setup, OpenClaw Launch runs Hermes Agent with inference included and a free trial to start. No model configuration, no server, and the messaging channels are already wired up.

Which Should You Pick?
- Just trying Hermes today: OpenCode Free. It is the only option with nothing to sign up for.
- Privacy or offline: llama.cpp or Ollama locally.
- Want to compare models: OpenRouter's free pool.
- Images or documents: Gemini's free tier.
- Want it running 24/7 without a server: a managed trial.
The Honest Caveat
Free model tiers are the first thing providers cut when capacity gets tight, and an agent is a heavier consumer than a chat window — it can fire many calls per turn. Free routes are excellent for learning, prototyping and personal bots. For anything you would be annoyed to see break, budget for a paid model or hosted inference.
