Voidleap Code is a desktop agentic IDE from Voidleap that runs on your own machine, with every agent, skill, hook, and security rule left editable. You can change model in the middle of a thread, planning on one, implementing on another, and reviewing on a third without starting over, then read back the tokens, cost, latency, and cache hit rate for each. Opper ships inside the app as a provider rather than a base URL override, so you add your key once in settings and pick Opper models per turn.
Voidleap CodeoninIn Voidleap Code, go to Settings → Providers → Add Provider, choose Opper, and paste your API key. Then pick GPT-6 Luna.
GPT-6 Luna 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.

GPT-6 Luna, OpenAI's fastest and most efficient GPT-6 model for focused, high-volume work like extraction, summarization, and classification, with a 1.05M-token context and six reasoning effort levels.
Step-by-step setup for running Voidleap Code 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.
