Cursor Settings → Models.
2
Paste the key
Turn on OpenAI API Key and paste fetch_....
3
Set the address
Turn on Override OpenAI Base URL:
text
https://api.zukko.pro/v1
4
Add a model
Use a name from the table below, for example cursor-sonnet-5.
5
Check
Press Verify, pick the model in chat and type "Hi".

Model names

Cursor sends standard names like claude-sonnet-5 past Zukko. Use these instead:

Name for Cursor	Model
`cursor-opus-55`	Claude Opus 5.5
`cursor-opus-5`	Claude Opus 5
`cursor-opus-48`	Claude Opus 4.8
`cursor-opus-47`	Claude Opus 4.7
`cursor-opus-46`	Claude Opus 4.6
`cursor-sonnet-5`	Claude Sonnet 5
`cursor-gpt-sol`	GPT-5.6 Sol
`cursor-gpt-terra`	GPT-5.6 Terra
`cursor-gpt-luna`	GPT-5.6 Luna
`cursor-qwen`	Qwen 3.8 Max

For models not in the table, use the standard name if Cursor accepts it: gpt-6.1-sol, gemini-3.8-flash, deepseek-v4.1-flash, glm-5.3. Old names (cursor47, cursor46, cursor46s, cursorgpt54, cursorgpt55) still work.

If it doesn't work
