Run Hermes on Grok 4.5

Name: Hermes
Author: Nous Research

Hermes is an open agent from Nous Research, the team behind the Hermes family of open-weight models. It runs as a terminal agent for general assistant and tool-use workflows, designed in the open and built to be steerable and unopinionated rather than locked down. On Opper it runs on a single key across 300+ models with full observability and a choice of region.
