Настройка Cursor

1. What Cursor is and what to prepare

Cursor is an AI IDE based on VS Code. It supports chat, code generation, edits, and explanations directly in the editor.

Before connecting Cursor through RouteAPI, prepare:

Install the desktop app from the Cursor website and sign in with your Cursor account.

Open Settings in Cursor, then go to Models.

Find the OpenAI settings on the Models page. Field names may vary by Cursor version, but the required information is:

After entering the values, click Verify.

After verification succeeds, open Cursor’s model picker and select an available OpenAI-compatible model returned by RouteAPI.

A safer approach is:

Prefer a standard chat or coding model marked as OpenAI protocol in the RouteAPI console
Do not prioritize reasoning models, because Cursor’s official docs state that custom OpenAI API keys only support standard, non-reasoning chat models

After configuration, you can use RouteAPI models directly in Cursor Chat or Composer.

The custom API key path mainly affects Chat / Composer standard chat capabilities and does not replace every built-in Cursor capability
Tab Completion, some Agent capabilities, or features that require dedicated models may still use Cursor’s built-in models
According to Cursor’s official FAQ, API keys are not stored, but each request is still sent to Cursor’s servers for final prompt assembly

If Verify fails, check the API key and ensure the address is https://www.routeapi.ai/v1
If the expected model is missing, confirm that it supports the OpenAI protocol and is a standard chat model rather than a reasoning model
If you updated the key or address but Cursor still shows the old state, close and reopen Cursor, then run Verify again
