Continue is an open-source AI code assistant that lives inside VS Code and JetBrains, giving you chat, inline edits, autocomplete and custom assistants against whichever models you configure. Add an Opper entry to ~/.continue/config.yaml with the openai provider and our base URL, and every role you assign it runs on any of 700+ models, with a choice of EU or US inference on one key.
Paste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
GPT OSS 120b runs on the routes below. Route only to EU providers when your data has to stay in Europe. One route also sells flex and priority processing: the same model at another price, picked per request with service_tier. How service tiers work.
