Run Claude Code on GPT-5
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.

Set up with agents
Paste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
Where you can run it
GPT-5 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.
