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.
OmniRouteoninIn OmniRoute (v3.8.51 or later), open Providers → API key providers, pick Opper and paste your key; on older builds add a custom OpenAI-compatible provider with base URL https://api.opper.ai/v3/compat. Then pick GLM-5.3-Flash.
GLM-5.3-Flash runs on the routes below. Route only to EU providers when your data has to stay in Europe.

GLM-5.3-Flash by Z.ai is a natively multimodal 320B MoE with 18B active parameters, hybrid sparse and linear attention, a 1M-token context, and MIT open weights for coding and agent work.
Step-by-step setup for running OmniRoute on each of these models through Opper.
Anthropic's terminal coding agent. Run it on any model on Opper, not just Claude.
opper launch claude
OpenAI's open-source coding CLI. Run it on any model on Opper.
opper launch codex
DeepSeek's open-source coding agent. Add Opper as a custom provider to run it on any model, not just DeepSeek's.
