Configure Hermes Agent with AnRouter

Add AnRouter as a custom endpoint through Hermes Desktop or the CLI, then verify it works.

The recommended setup uses hermes model to add a custom endpoint. Current Hermes documentation uses the top-level custom_providers list for named custom endpoints; the manual example below follows that documented schema.

1. Hermes Desktop visual setup

Open model/provider setup during first launch, or reopen it later from the model settings.
Choose Local / custom endpoint, set Endpoint to https://api.anrouter.com/v1, and enter the AnRouter API key.
Use an exact model ID such as glm-5.3. If API mode appears, choose chat_completions.
Save, start a new session, and send a short test message.

2. Install the CLI

# macOS / Linux / WSL2
curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash

hermes --version
hermes doctor

Windows PowerShell: iex (irm https://hermes-agent.nousresearch.com/install.ps1)

3. CLI recommended: interactive setup

hermes model

Provider	Custom endpoint
API Base URL	https://api.anrouter.com/v1
API Key	AnRouter API key
Model	glm-5.3
API Mode	chat_completions
Context length	Leave blank for endpoint discovery when possible; otherwise use the model catalog

4. Optional: named provider configuration

# ~/.hermes/config.yaml
custom_providers:
  - name: anrouter
    base_url: https://api.anrouter.com/v1
    key_env: ANROUTER_API_KEY
    api_mode: chat_completions

model:
  provider: custom:anrouter
  default: glm-5.3

# ~/.hermes/.env
ANROUTER_API_KEY=your_anrouter_api_key

5. Verify

Run hermes doctor to check the installation and configuration.
Start hermes and send a short prompt first.
Use /model custom:anrouter:glm-5.3 in a session. Exit and run hermes model to add or change a provider.

Context requirement: Hermes requires at least 64,000 tokens for agent tool workflows. Leave the wizard field blank when endpoint discovery is available; only add context_length manually when it matches the current AnRouter model catalog and actual endpoint behavior.
