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 700+ models with full observability and a choice of region.
HermesoninPaste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
Kimi K3 runs on the routes below. Route only to EU providers when your data has to stay in Europe. One route also sells priority processing: the same model at another price, picked per request with service_tier. How service tiers work.
