Cursor

Configure

1. Open Cursor Settings → Models.
2. In OpenAI API Key, paste your sk-orynx-... key.
3. Turn on Override OpenAI Base URL and enter https://api.orynx.dev/v1.
4. Add the model ids you want as custom models, for example kimi-k3, glm-5.3 or claude-sonnet-5, and turn them on.

Notes

• Cursor sends every request through its own servers, not from your computer. Do not set an IP allowlist on a key you use in Cursor.
• Cursor Tab (autocomplete) always uses Cursor's own models and is not billed to ORYNX.
• Cursor calls custom models over Chat Completions, Claude included. ORYNX serves Gemini models only in the Gemini format, so they do not work in Cursor.
• With a custom base URL, Cursor can send GPT models a Responses-format request on /chat/completions, which fails. This is a known Cursor bug. Use GPT models from Codex CLI instead, or pick another model in Cursor.
