Run OmniRoute on Qwen3.5 4B

by Diego SouzaCoding agentomniroute.online

OmniRoute is an open-source gateway you run yourself: one endpoint in front of 350 providers, with quota-aware fallback, token compression, and MCP support, built for Claude Code, Codex, Cursor, OpenCode, Cline and Copilot. Opper is listed in its provider catalogue, so you paste your Opper key once under Providers and every agent you point at OmniRoute can pick from Opper's 700+ models, EU-hosted routes included, alongside whatever else you have configured.
