Kilo Code is an open-source AI coding agent for VS Code. It combines autonomous editing, planning and architect modes, and a provider catalogue built from the open models.dev listing, where Opper is one of the providers. Pick Opper, paste your key, and you can run it on any of 700+ models on one gateway, with a choice of region.
In Kilo Code, open Settings → Providers → Show more providers, search for Opper and paste your Opper key. Then pick Gemini 4 Argon.
Gemini 4 Argon runs on the routes below. Route only to EU providers when your data has to stay in Europe. Some routes also sell flex and priority processing: the same model at another price, picked per request with service_tier. How service tiers work.
