Run Goose on o3
Goose is an open-source AI agent that goes beyond code suggestions: it installs dependencies, runs and tests code, and automates whole engineering workflows from the terminal or its desktop app. Created by Block and now part of the Linux Foundation's Agentic AI Foundation alongside MCP, it is built to be model-agnostic. Opper ships in its provider list, so you pick Opper, paste your key, and Goose runs on any of 700+ models with a live model list.

Add Opper in Goose
In Goose (v1.49 or later), run goose configure → Configure Providers → Opper, or in the desktop app open Settings → Models → Configure providers → Opper, then paste your Opper key (stored as OPPER_API_KEY). Then pick o3.
Where you can run it
o3 runs on the routes below. Route only to EU providers when your data has to stay in Europe. Its route also sells flex and priority processing: the same model at another price, picked per request with service_tier. How service tiers work.
| Provider | Region | Zero data retention | Training | Input | Output | Cache read | ||
|---|---|---|---|---|---|---|---|---|
| US | No | $2.00 | $8.00 | $0.50 |
