Cursor

Cursor is an AI code editor built on VS Code. Its Override OpenAI Base URL setting sends requests from Cursor’s OpenAI slot to Flow AI instead of OpenAI.

1

Create a key

Create a key for Cursor on API keys. Give it a spending limit; see Limits.

2

Point Cursor at Flow AI

  1. Open Cursor Settings (Cmd/Ctrl + ,) and go to Models.
  2. Expand API Keys and turn on OpenAI API Key.
  3. Paste your Flow AI key into OpenAI API Key.
  4. Turn on Override OpenAI Base URL and set it to:
https://ai.hyperflow.fun/v1
3

Add models

Under Models, choose + Add model and enter a Flow AI model id, such as openai/gpt-6-luna. Copy ids from the Models page.

4

Pick the model

Open the model picker in chat or agent and choose the model you added. Its requests now go through Flow AI.

Limits

  • Tab completions always use Cursor’s own models; they don’t go through your key.
  • Auto mode may not use your key. See Cursor’s docs for its current behaviour.
  • Cursor sends the requests from its own servers, so Flow AI sees Cursor’s addresses, not yours.

Troubleshooting

  • Invalid API key: make sure you pasted the Flow AI key (sk-...) and that it’s turned on in the console.
  • Model not found: the id must match the Models page exactly, including the lab, such as openai/gpt-6-luna.
  • Base URL: it must end in /v1.
  • 402: your balance is too low.
