+Install the [Codex extension](https://marketplace.visualstudio.com/items?itemName=openai.chatgpt). The extension shares the same user-level Codex config as the CLI (`~/.codex/config.toml` on macOS/Linux, `%USERPROFILE%\.codex\config.toml` on Windows).

+Create or edit that file with the `fcc` provider pointing at your local proxy:
+
+```toml
+model_provider = "fcc"
+model = "nvidia_nim/nvidia/nemotron-3-super-120b-a12b"
+
+[model_providers.fcc]
+name = "Free Claude Code"
+base_url = "http://127.0.0.1:8082/v1"
+env_key = "FCC_CODEX_API_KEY"
+wire_api = "responses"
+```
+
+Set `model` to your Admin UI `MODEL` value. Replace `8082` if your proxy uses a different `PORT`.
+
+Store the proxy auth token in `~/.codex/auth.json` (or the Windows equivalent):
+
+```json
+{
+  "FCC_CODEX_API_KEY": "freecc"
+}
+```
+
+Use the same value as `ANTHROPIC_AUTH_TOKEN` in the Admin UI. Restart VS Code after changing these files. On Windows with WSL-backed Codex, edit the WSL `~/.codex/` files instead and enable `chatgpt.runCodexInWindowsSubsystemForLinux` in VS Code settings when needed.
