Claude Code is Anthropic's agentic coding tool for the terminal. It reads your whole repository, plans and applies changes across files, runs commands and tests, and iterates on failures from natural-language prompts — all without leaving the shell, on macOS, Linux, and Windows. On Opper it runs on any of 700+ models, not just Claude: pin one with a single --model flag, switch mid-task without losing context, and choose EU or US hosting on one key.
Claude CodeoninPaste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
GPT-6 Luna Decisions runs on the routes below. Route only to EU providers when your data has to stay in Europe.
| Provider | Region | Zero data retention | Training | Input | Output | Cache read |
|---|---|---|---|---|---|---|
| US | No | $0.10 | $0 | Input price |
OpenAI Decisions model: typed predicate, choice and score answers with probabilities and confidence. Text and inline base64 image input. Use POST /v3/compat/decisions (OpenAI Decisions format; a bare gpt-6-luna resolves here) or POST /v3/compat/v1/systemone with model openai/gpt-6-luna-decisions (System One format, text only).
Step-by-step setup for running Claude Code on each of these models through Opper.
