When to use it

Hermes image v2026.7.1 or later and credentials for each referenced provider are required.

Install

helm upgrade --install hermes-agent ./charts/hermes-agent \
  --namespace hermes-agent --create-namespace \
  -f charts/hermes-agent/values-moa.yaml \
  --set-string env.OPENROUTER_API_KEY='<real-value>' --wait

When an example requires more than one credential, pass every listed value with --set-string or use extraEnvFrom to reference an existing Secret.

Adapt before deploying

Replace the preset reference and aggregator models for your workload.

# values-moa.yaml
#
# Hermes Agent using Mixture-of-Agents (MoA): reference models run in
# parallel and an aggregator model synthesizes their output, instead of a
# single model answering directly. MoA is a virtual provider (image
# v2026.7.1+): `config.model.provider: moa` + `config.model.default: <preset
# name>` selects a named preset defined under `config.moa.presets`.
#
# The example preset below fans out to two OpenRouter reference models and
# aggregates with a third: swap provider/model ids for whichever you use,
# and supply each provider's own API key under `env` (a preset can mix
# providers freely).
#
#   helm upgrade --install hermes-agent ./charts/hermes-agent \
#     --namespace hermes-agent --create-namespace \
#     -f charts/hermes-agent/values-moa.yaml \
#     --set-string env.OPENROUTER_API_KEY='sk-or-<real>' --wait
