Hermes

Add opengateway as a named custom provider in ~/.hermes/config.yaml and switch with /model in any Hermes session — your default model stays untouched.

Copy this to your agent

Paste it into any AI agent. It sets up everything and saves it as the opengateway-hermes skill.

Set it up by hand#

1. Get an API key#

opengateway.ai → API Keys → Create Key. Export it in your shell profile (~/.zshrc or ~/.bashrc):

export OPENGATEWAY_API_KEY="YOUR_OPENGATEWAY_API_KEY"

2. Add the provider#

Add to ~/.hermes/config.yaml:

custom_providers:
  - name: opengateway
    base_url: https://apis.opengateway.ai/v1
    key_env: OPENGATEWAY_API_KEY

3. Switch and verify#

Inside a session, /model opens the picker — choose opengateway, then a model. Or switch directly (any catalog model ID works):

/model custom:opengateway:z-ai/glm-5.2-ultrafast

Send "Reply with OK". A response means it works — the call is already on the dashboard with tokens, cost, and latency.
