Hermes Agent

API: Anthropic API · OpenAI API

Open or create ~/.hermes/config.yaml and add Imbutus as a custom provider. Anthropic Messages API is recommended (native format), with api_mode "anthropic_messages":

model:
  default: huihui-ai/Huihui-Qwythos-9B-Claude-Mythos-5-1M-abliterated
  provider: custom
  base_url: https://imbutus.com
  api_key: <your-api-key>
  api_mode: anthropic_messages
  context_length: 246416

To use the OpenAI-compatible API instead, set api_mode to "chat_completions" and point base_url at the /v1 endpoint:

model:
  default: huihui-ai/Huihui-Qwythos-9B-Claude-Mythos-5-1M-abliterated
  provider: custom
  base_url: https://imbutus.com/v1
  api_key: <your-api-key>
  api_mode: chat_completions
  context_length: 246416

To switch model for a single session, use the --model flag:

hermes chat --model <model-id>
