Use g0i in Cursor

A fork of VSCode built around AI pair-programming. Custom models work via Cursor's OpenAI-compatible custom endpoint.

Why pair Cursor with g0i

Use Claude Opus 5.5 and Sonnet 5 in Cursor without paying Cursor Pro
Same key works across Cmd-K, Cmd-L, and the agent panel
GPT-6 family + Gemini 3.1 + Kimi + Qwen — pick best-for-task
No vendor lock-in — same key works in Cline, claude-code, codex

Setup — 2 minutes

Cursor settings → Models → "Add custom model". Then point base URL at g0i. Works on macOS and Windows.

Custom Base URL

https://api.g0i.ai/v1

Troubleshooting

Cursor "Verify" button fails

g0i's /v1/models endpoint is fully open. If verify fails, double-check there's no trailing slash and the key has no extra whitespace.

Custom models don't show in picker

Cursor caches the model list — restart Cursor after adding new model names.

Tab autocomplete still uses Cursor's own model

Tab completion uses Cursor-tuned models and isn't affected by custom OpenAI provider settings. Cmd-K and Cmd-L use g0i.
