Prism Provider for Hermes Agent
Use Prism models in Hermes Agent through Prism's OpenAI-compatible Chat Completions API.
Install
hermes plugins install prismhq/hermes-prism-provider
The installer prompts for PRISM_API_KEY and stores it in the active Hermes
profile. Create a key at
prisminference.com/app/settings/api-keys.
Select Prism and its recommended model:
hermes config set model.provider prism
hermes config set model.default deepseek-v4.1-flash
You can also select Prism interactively with hermes model.
